Latest Patents

Jae Bum Yu holds a patent for a process titled "Process for etching tungsten silicide overlying polysilicon particularly in a flash memory." This method involves plasma etching tungsten silicide over polysilicon, which is especially useful in creating flash memory that requires both densely packed areas and open (iso) areas. The technique addresses the challenges of microloading by decreasing wafer biasing during the over etch process. The principal etchants used in this method include NF and Cl, with argon added to prevent undercutting at the dense/iso interface. Additionally, oxygen and nitrogen are utilized to oxidize any exposed silicon, enhancing etch selectivity and straightening the etch profile. SiCl may also be incorporated for further selectivity.
