Functional Modeling of a Vacuum Cleaner: A Pathway to Innovation

Projects dedicated to mechanical engineering

Vacuum cleaner Functional modeling

Anything related to the cubic measure of space occupied by an object or the space around it.   'Moving' includes any situations where there is any degree of relative motion or mobility between two or more parts related to the problem.  This relative motion may be a few microns or a considerable distance.

Volume of moving object

Taking Out (Extraction)

Universality

Preliminary action

Discarding and recovering

The number of useful (value-adding) functions or operations performed by a system per unit time.  The time per unit function or operation.  Useful output per unit of time.  Cost per unit output, or amount of useful output.  (See 'Speed' –  #14 – which is more focused on issues of dynamics rather than the output of product.)

Productivity

The extent to which a user is able to learn how to operate, operate or control a system or object.  The convenience of use.

Ease of operation

The battery charges and supplies electricity for the DC motor

The Other way around

Periodic action

Loss or waste of energy that does not contribute to any of the useful functions being performed.  Inefficiency.  Can be partial or complete, permanent or temporary.

Loss of energy

Any interaction that is intended to change an object's condition.  Can be linear or rotational; the term applies equally well to torque.

Force

Mechanical vibration

Copying

Parameter changes

System' Complexity – The number and diversity of elements and element interrelationships within and across the boundaries of a system.  The user may be an element of the system that increases the complexity.  Includes issues like the number of functions, number of interfaces and connections, excessive number of components.    'Control' Complexity – complexity of the control system – either physical components or the algorithms that it contains- used to control a system in delivering useful functions.

Device complexity

Battery consumes energy even without usage

The measure of an object's capacity for doing work.  This parameter focuses on the actual amount of energy (rather than the efficiency of its use, see 27).  'Moving' includes any situation where there is any degree of relative motion between two or more parts related to the problem.  The relative motion may be a few microns or larger amounts.

Use of energy by moving object

Equipotentiality

Mechanics substitution

The measure of an object's capacity for doing work.  This parameter focuses on the actual amount of energy (rather than the efficiency of its use, see 27).  'Stationary' includes any situation where there is no form of relative motion between two or more parts related to the problem.

Use of energy by stationary object

Local quality

Porous materials

The amount, quantity, or a number of a system's materials, substances, parts, fields or sub-systems.  'Substance' is used in its most generic form in the TRIZ context to include any physical or temporal 'thing'.

Quantity of substance/the matter

Any linear or angular dimension relating to a stationary object.   'Stationary' includes any situations where there is no form of relative motion between two or more parts related to the problem.

Length of stationary object

Define the more contaminated areas and spend more time/chemical to clean the specific areas

Increase the temperature of the solution to make the process more effective

Principle #15 – Dynamism – change an object from rigid to movable or adaptiveThe idea that is generated is as follows:Replace the constant flow of the chemistry with variable flow, especially in the and of the process, to ensure defects removal from the disc.So, the idea is to change (even make pulses) flow while the cleaning process.

לטבול את הצלחת במים במקום לשטוף אותה בכל פעם

מערכת כיווון אוטמיטת למסוע

The wafer is contaminated not equally. Use special cleaning on the areas that are more contaminated

The general conclusion is to eliminate the system of the air supply and exhaust. Let air enter the chamber and convert exhaust to drain with very little under-pressure. The will stabilize the performance, reduce the cost and make the system more simple.

Principle #16 – Partial or accessive action – do slightly more or slightly lessIf 100 percent of an object is hard to achieve using a given solution method then, by using 'slightly less' or 'slightly more' of the same method, the problem may be considerably easier to solve.A wafer is not contaminated equally: there are some areas with more defects and some areas with fewer amount of defectsThe idea is to use the shower with a graduated flow - the more the defects the higher the flow

Principle #13 – The other way around – Turn the object “upside-down”This is a great tip. Indeed, why the disk is kept “face-up” during the washing process?It would be much better to keep the disc “face down” to improve the removal of the defects from the surface.So, the idea is to keep the wafer “face down” during the washing process﻿<img

Improve the rinsing process to ensure the defects removal

Improve the process to enhance the effectiveness of the cleaning with the chemistry

Wet cleaning is widely used in microchip manufacturing. Single wafer equipment is working as follows. A wafer rotates, and chemistry is poured from a movable nozzle. Water rinsing is performed at the end of the process.
Loading of a new batch of the chemistry resulted in excursion - a strongly increased amount of defects was observed on the wafer after the processing.
The project is dedicated to the failure analysis and creation of innovative solutions.

The time that an object or system takes to perform an action.  The action may take place over a few milliseconds, or over several years or more.  The parameter is different from 'reliability' (Parameter 35) which is connected to the idea of the time to failure of a system – where it is specifically only the time duration aspect that is at issue.  'Moving' includes any situation where there is any degree of relative motion between two or more parts related to the problem.  The relative motion may be a few microns or considerable distances.

Duration of action by a moving object

Because the chemistry contaminates the wafer due to impurities or some other properties

The chemistry is removed from the wafer before it removes the defects

Defects remain on the wafer till the very end of the process.

Because the wet process does not remove the defects

Defects remain on the wafer surface after the wet cleaning process step

Try to eliminate the washing. Do we really need this?

To increase the density of the chemistry by temperature reduction.

Ensure that the chemistry remains on the wafer as long as possible (reduce rotation of the wafer)

Reduce evaporation rate of the chemistry, reduce rotation of the wafer

5+ WHYS Analysis

Increase the temperature of rinsing water

Defects remain on the wafer surface. The wet cleaning process suddenly becomes ineffective.Let's apply the Effective Brainstorming (EBS) tool to generate ideas and prioritize them.

To analyze why the defects remain on the wafer while cleaning with chemistry.The process is as follows:<ul><li>a wafer is kept in the special chuck in 4 points</li><li>chemistry pores from the nozzle on the wafer</li><li>the wafer rotates allows removing the chemistry from the wafer together with the defects</li><li>parameters of the process - chemistry flow, temperature, process time, wafer rotation rate and so on can be adjusted</li></ul>

Set up process containing wet operations only. 1 operation - Cu removal with H2SO4 + H2O2 (Chem 1) 2 operation - Ti removal with diluted HF (Chem 2)

Eliminate the dry etch operation and replace it with the wet etch with the diluted-HF solution.

Since CuF2 is water-soluble stuff, wash the wafers in water before running the final test

Manage the process flow to ensure the lowest dwelling time between the process end and the final test.

The project was dedicated to production yield improvement in microchip manufacturing.
The bumps are created on the top of a wafer and used for the final test of all dies. 
Only good dies are taken for the packaging. All dies that fail the test will be scrapped. The process yield depends on the amount of "good" and "bad" dies.
It was revealed that in some cases, the time between the end of the process and the final test impacts the yield. 
The longer the dwelling, the more dies fail the final test. 
If the dwelling exceeds hundreds of hours, the amount of failed dies becomes dramatically high, which results in the scrapping of the whole wafer.
The problem was analyzed and solved.

The dry etch operation is performed with the fluorine compound

The dry etch process contaminates the bump with fluorine that converts slowly to the CuF2 that covers the surface of the bump

Previous process affected the bump surface that results in the formation of dielectric stuff on the surface of the bump.

Some stuff that has high resistivity is formed on the surface of the bump.

The resistivity of the bumps increases during the dwelling

Dwelling time before the final electrical test results in the dies failing

Manage the process flow to achieve the lowest dwelling time

Eliminate the dry etch operation. Replace it with the relevant wet etch process.

The best way to eliminate high resistivity on the surface of a bump is to use a chemical etching process.

One way to eliminate this dielectric stuff on the surface of the bump is to clean the bump surface with a solvent or chemical solution. This will help to remove any residue or contaminants that may have been left behind from the previous process. Additionally, it is important to ensure that the surface of the bump is dry before any further processing takes place. If necessary, the bump can also be polished to remove any remaining dielectric material.

One way to eliminate this contamination is to use a wet etch process instead of a dry etch process. Wet etching is a chemical process that uses an aqueous solution to remove material from the surface of a substrate. This process does not involve fluorine, so it will not cause the formation of CuF2 on the surface of the bump. Additionally, wet etching can be more precise and can produce better results than dry etching.
As a temporary solution - wash the wafers with water prior to the final test.

The best way to eliminate the use of fluorine compounds is in a dry etch operation. Eliminate the dry etch operation at all.

The operation aims to remove Cu from the surface of the wafer. The process - Wet etch with H2SO4 + H2O2 solution that dissolves Cu and does not dissolve TiProduct - Dissolved Cu

1. Cu removal with H2SO4+H2O2

The operation aims to remove Ti on the open area between the bumps.The process - Dry etch (plasma) with NF3 gas. Fluorine generated from NF3 in plasma interacts with Ti and converts it to TiF4 with low melting and boiling points. At the process conditions, TiF4 presents in the form of gas that is removed by the exhaust of the dry etch chamber. Product - TiF4 - gas

2. Ti removal between bumps with NF3 plasma

The operation aims to remove the residue of Ti remains between the bumps after the dry (plasma) etch operation.The process is performed by wet cleaning using diluted HF solution (Chem 2). HF solution dissolves rare refractory metals including Ti. HF converts the Ti to soluble acid H2TiF6. Dissolved Ti is removed from the wafer with liquids Product - Dissolved Ti

3. Ti residue removal with HF solution

During the loading, the lowest thermocouple received the wrong information; therefore, the bottom part of the furnace became overheated.

The quality of the low-zone wafers is different from the mid-zone and top-zone wafers. For instance, the stoichiometry of SiO2 might change. Even small variations of stoichiometry can result in the same change in optical constants that may affect the model of ellipsometric model and result in SiO2 thickness.

Turn off the heaters of the furnace when the boat is removed. The furnace is big enough to keep the temperature for a long time. Besides, the STABILIZATION step is long enough to compensate for the temperature difference.

Use a mixture of N2 and Ar during LOADING to ensure that all residual air is moved out, even from the bottom zone of the furnace.

Disconnect the thermocouples control during the LOADING if the furnace is turned on.

Start N2 flow just before the LOADING, before the loading of the boat with wafers into the furnace. Turn on the heaters only when the boat is completely loaded into the furnace

Turn off the heaters of the furnace and N2 flow during PRE-LOADING - loading the wafers in the boat

During the PRE-LOADING - loading wafers into the boat, the furnace remains open, resulting in losing N2 gas and electricity. It would be better to cover the bottom of the furnace.

The process is related to microelectronics - microchip manufacturing.

The purpose of the process is to create a SiO2 layer on the surface of a Si wafer.
Equipment: Vertical furnace to heat the wafers in the Q2 atmosphere and perform oxidation on the wafer surface.
Process: The oxidation occurs on the front side and on the back side of the wafer
Requirements: Create a SiO2 thin layer with a certain thickness and low sigma - low standard deviation of the thickness between the wafers and within the wafer

Failure: Wafers from the lower zone have higher thickness and significantly higher within wafer sigma (standard deviation of the thickness within the wafer)

SiO2 THICKNESS MEASUREMENT

In the event of a global conflict (World War III) leading to Egypt's isolation from international markets and resources, businesses and citizens will face critical challenges in sustaining essential needs such as food, energy, communication, and financial stability. To address this, there is an urgent need for an application-based solution that ensures economic resilience, local resource optimization, and crisis management. This solution should leverage innovative strategies like the 9 Window Model, Effective Brainstorming, and Action Preventing Action to develop a sustainable business model that transforms this crisis into an opportunity.

In response to the potential outbreak of a third world war and the risk of Egypt becoming isolated from global trade and financial systems, this project aims to develop a self-sustaining, decentralized digital ecosystem. The goal is to ensure economic stability, resource accessibility, and secure communication for citizens, businesses, and the government in times of crisis.

This solution will be delivered as an application-based platform that integrates barter trade, digital currency, AI-driven supply chain management, emergency communication, and cybersecurity measures. By leveraging blockchain technology, AI-powered logistics, and decentralized networking, the platform will enable uninterrupted trade, resource distribution, and crisis coordination without reliance on external financial institutions or internet-based infrastructure.
