SiO2 thin film creation in Diffusion furnace - Process Functional Modeling

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.

Flash heating of a wafer is widely used in microchip manufacturing. The purpose of the process is to prevent the diffusion of ions and atoms. During the flash process, a wafer breakage occurs. The project's purpose is to learn and understand the mechanism of the wafer breakage and propose the solutions to prevent the wafer breakage

The number of particles is a critical parameter for microchip manufacturing. Each, even a very small particle, can potentially destroy a die. Therefore filters are widely used. Water is always filtered through fine filters to reduce the number of particles. Nevertheless, if the filter is too fine, it could cause a problem. This issue was investigated with the help of Functional Modeling. Possible solutions were generated using 40 Inventive Principles.
