Latest Patents

One of his latest patents is a method of fabricating a high density, low power, merged vertical fuse programmable ROM. This invention includes a wafer for a CMOS-type structure that features an emitter, which is overlain by a fuse pad made of undoped polysilicon and a conductive layer. The design incorporates a layer of barrier oxide on the conductive top layer of the fuse pad, along with a sidewall oxide surrounding the periphery of the fuse pad, both of which are covered by a metallic electrical connection. The process for producing this fuse programmable ROM utilizes standard CMOS fabrication techniques, including steps for depositing fuse material and forming electrical connections.

Another significant patent involves the use of selectively deposited tungsten for contact formation and shunting. This process is designed for creating ohmic contacts and contact/interconnect metallization patterns. It allows for the interconnection of fully formed field effect devices using contacts through a dielectric layer. The method includes conformally depositing a thin layer of intrinsic polysilicon or amorphous silicon, which is then patterned and covered by selectively deposited tungsten. An anneal operation forms self-aligned contacts or shunts, enhancing the efficiency of the devices.
