In past decades, polymeric micropillar devices have gained a great deal of attention in micro and nano technology research as the result of their potential and practical usage in many applications. This project is going to deal with the process of how to fabricate the magnetic micropillars, from the beginning â the planning and design, improving the existing process, lithography to create the base silicon mold and then creating the PDMS pillars that contains nano magnetic particles of Fe_3 O_4, the process today is not efficient enough in terms of cost and time and we are wishing to improve it, in the end we will have a device with micro-pillars that can move correspondingly to external magnetic field which will help us to do many advanced experiments in the biology field like using the device for cell stimulation.
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.
To reduce high turnover at the plant the managers propose different ideas, but it does not help. All proposed solutions are good, but there are some of them that are blocking the effectiveness of the rest of the solutions. The purpose of the project is to analyze the proposed solutions (perceptions) and define the blocked. The solutions with high blocking rank should be completed first to ensure the effectiveness of the rest of the ideas. The Perception Mapping (PMap) creative thinking tool was used for the blockers definition.

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.
