This project have few problems we need to solve, the first problem is how to make multiple devices at the same time and reduce clean room time
today in the literature we are fabricating holes mold in the silicon as can be seen in the picture bellow:
we can see here that the area that need to exposed is very large and it leads to long process in the clean room
the solution is to produce the negative picture of this and create silicon pillars instead:
so we get:
after the pillars are ready we can start creating PDMS holes mold from it, first of all we will apply anti adhesive coating so we can reuse the pillars and then we will cast the pdms on it to create the mold, this will allow us to create multiple molds outside the clean room - simple and fast!
now we have multiple molds and we can create multiple devices at the same time.

This is a great project. You made excellent analysis and got to the best solution. Your project confirms again the powerful of the Functional Modeling and 40 Inventive Principles. Continue to use the platform.
The project addresses instability in the dissolution of tantalum (Ta) anodes in hydrofluoric acid (HF), where hydrogen gas generated during the reaction becomes trapped in the solution, forming foam that disrupts the process and creates safety risks. Using the PRIZ Platform, a Functional Model of the system was developed. The model revealed that the HF solution is both the most functional and the most problematic component, leading to a physical contradiction: HF must interact with Ta anodes to enable dissolution, but must not retain the hydrogen gas produced during the reaction. Applying the PRIZ principle of Separation in Space, two reactor concepts were proposed: a spray interaction reactor, where HF is pumped to spray onto anodes placed above the solution, and a surface wetting reactor, where anodes are positioned at the top of the solution, allowing natural circulation and easy hydrogen release. Both designs eliminate foam formation and provide a stable, controllable, and safer dissolution process.
Chilled water is used for production equipment cooling. Suddenly pH of the water started to drop. The aim of the project is to analyze the issue, understand the root cause, and propose solutions to the problem.
