Latest Patents

Barbara's latest patents encompass methods that enhance the manufacturing processes of semiconductor structures. One noteworthy invention is the "Method for filling trench and relief geometries in semiconductor structures." This method teaches how to effectively fill trench structures formed in a semiconductor substrate, where a first deposition process is used to create a primary filling layer with high conformity and minimal roughness. Following this, a V-etching process is performed to produce a V-profile within the trench structure, thereby improving the efficiency of semiconductor fabrication.

Another patent focuses on the "Method of forming an isolation layer and method of manufacturing a trench capacitor." This innovation introduces a two-step etch process to create a vertical collar oxide within the upper portion of a trench capacitor. The initial step employs CF/SiF/O chemistry, concluding when the bottom of the collar within the trench is exposed while preserving a thin oxide layer on the PAD-nitride surface. The subsequent step utilizes CF chemistry to eliminate the remaining silicon oxide layer. This meticulous process guarantees uniform thickness of the PAD-nitride layer and adequate collar oxide thickness, proving essential for deep trench capacitors used in DRAM devices.
