Today we creating silicon mold with holes - creating this kind of pattern takes a lot of time.
in the end we need to create some mold of holes, abut what if we will create in the clean room silicon pillars instead of holes the pillars have less area that need to be exposed so the lithography should be faster. after that we can take this pillar mold and create negative mold of holes from PDMS, as many as we like because creating the molds will take now half an hour for each mold and there will be no need to go to the clean room any more.

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.
