Latest Patents

One of his latest patents is titled "In situ hardmask pullback using an in situ plasma resist trim process." This invention provides a process for manufacturing an isolation structure for use in semiconductor devices. The process involves forming an opening in a substrate through a patterned photoresist layer and a hardmask layer located over the substrate with plasma. It also includes trimming the photoresist layer with plasma to create an exposed portion of the hardmask layer, removing the exposed portion with plasma to create a trench guide opening, and creating a trench through the trench guide opening with plasma.

Another significant patent is the "Method for patterning sub-lithographic features in semiconductor manufacturing." This method describes the formation of a gate electrode for a metal-oxide-semiconductor (MOS) integrated circuit. It involves depositing a hardmask layer over a polysilicon layer, forming an anti-reflective coating layer, and photolithographically patterning the photoresist to define the gate electrode pattern. The pattern is then transferred to the hardmask layer, allowing for the definition of gate electrodes with widths narrower than the minimum dimension available through photolithography.
