Project Poster | Optimizing IC Interconnection: A Functional Approach to Innovation

Semiconductor devices are becoming more complex and expensive. But what exactly are we paying for when we buy a computer, cellphone, or any device containing a microchip? It’s not for radically new functions—the core components remain the same: transistors and interconnections. According to Moore’s law, transistors are getting smaller, with more interconnection layers added, making the manufacturing process longer and more costly. In reality, we’re paying for the inability of engineers to efficiently solve engineering challenges. This project leverages System Functional Modeling (SFM) to analyze the IC interconnection layer and Process Functional Modeling (PFM) to evaluate its manufacturing process. These analyses aim to deepen our understanding of both the device and the production process, generating innovative solutions for cost reduction and improved efficiency.

Project Poster | Wafer cleaning issues in the wet process

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.

Project Poster | Diffusion furnace - Process Functional Modeling (PFM)

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)

Project Poster | BGR CFRP Monocoque challenge

The integration of CFRP materials into automotive designs presents challenges related to compatibility, performance, and safety, necessitating a careful transition from a Chromolly tubular space frame to a CFRP monocoque. Key considerations include determining the optimal geometry for suspension, aerodynamic features, and the placement of components like the battery pack and sensors, all while adhering to FSAE safety protocols. Additionally, decisions regarding the production method—whether to use preimpregnated carbon fibers or an injection method—must be made early to facilitate timely production. The development process involves creating molds and plugs from suitable materials, ensuring that all assemblies can be connected without compromising structural integrity, and maintaining strict adherence to budget constraints and sourcing of materials.

Project Poster | Abdelrahman Nashed - Strategic Problem Evaluation

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.
