With a total of 2 patents, his work has advanced the understanding and implementation of innovative manufacturing processes.

Latest Patents

Nadeem S Alvi's latest patents include two groundbreaking inventions. The first is titled "Grown side-wall silicided source/drain self-align CMOS fabrication." This process involves the outdiffusion of implanted ions in a patterned refractory silicidable layer to form the source and drain regions of CMOS devices. The oxidation of the sidewalls of openings formed in the layer serves to isolate it from the polysilicon gate electrode, which is later formed in these openings.

The second patent is "Method of fabricating silicon-on-insulator like devices." This process focuses on forming MOS transistors where the source and drain regions interface only with the channel portion of the silicon substrate, thereby minimizing parasitic capacitances. The method involves covering a monocrystalline silicon substrate with a layer of silicon oxide, creating a hole for the transistor channel, and epitaxially growing silicon to fill the hole. The laterally grown regions serve as the source and drain, while a polysilicon gate region is formed over the gate oxide.
