Latest Patents

Boo-sup Lee holds a patent for a thinner composition used in the washing process for manufacturing semiconductor devices. This composition includes at least ethyl lactate (EL) and ethyl-3-ethoxy propionate (EEP), and preferably, it also contains Gamma-butyrolactone. The thinner composition is characterized by high volatility and low viscosity, which allows for a sufficient solubility rate when rinsing photoresist on the wafer. This innovation effectively removes photoresist from the edge or backside of a wafer at a rapid rate, thereby enhancing the yield of semiconductor devices. Additionally, any remaining photoresist can be completely removed, enabling the reuse of the wafer and resulting in economic benefits.
