Latest Patents

One of Hung Chih Tsai's latest patents is a method for removing hard masks on gates in the semiconductor manufacturing process. This method involves forming a first gate and a second gate with hard masks on a semiconductor substrate, where the second gate is larger than the first. The gates are associated with silicon-germanium (SiGe) source and drain regions to form p-type transistors. A photoresist layer is then deposited, and an opening is formed on the hard mask of the second gate. The photoresist layer on both gates is completely removed by etching back, ensuring that there is no residue left. This allows for the complete removal of the hard masks on both gates.
