Latest Patents

Chiu-Te Lee holds a patent for a method of fabricating deep trench capacitors for DRAM cells. This patent outlines a detailed process that begins with the formation of deep trenches on a silicon substrate using oxide and nitride as etching masks. The process continues with the deposition of an ONO capacitor dielectric layer inside the trench, followed by the filling of the trench with a first polysilicon layer as the storage node. The method includes the formation of dielectric collars on the trench sidewalls, the creation of a sacrificial stud, and the subsequent removal of the stud through wet etching. Finally, a second polysilicon layer is deposited and etched back to complete the trench capacitor formation.
