Latest Patents

Fang's notable patent, titled "Method to control critical dimension of a hard masked pattern," describes an innovative approach to reducing the critical dimension (CD) of a hard mask using a wet etch method. The process involves treating an oxide hard mask with a HSO/HO(SPM) solution, followed by an NHOH/HO/HO (APM) solution, allowing for a CD reduction of 0 to 20 nanometers. This method is meticulously designed to ensure that with the use of nitride or oxynitride hard masks, a buffered HF dip is incorporated prior to the SPM treatment to optimize the etching process. The detailed method provides cutting-edge solutions for maintaining gate lengths of less than 150 nm while controlling the CD within a tight range of 3 to 5 nm of targeted values.
