Latest Patents

One of his latest patents involves a semiconductor device that features a gate trench across an active region of a semiconductor substrate. This device includes a gate structure that fills the gate trench and source/drain regions formed in the active region at respective sides of the gate structure. The gate structure consists of a sequentially stacked gate electrode and insulating capping pattern, along with a gate dielectric layer positioned between the gate electrode and the active region. Notably, the gate electrode is situated at a lower level than the upper surface of the active region and incorporates a barrier conductive pattern and a gate conductive pattern. The gate conductive pattern is designed with a first part having a first width and a second part with a greater width.

Another significant patent pertains to an ohmic layer and methods for its formation. This patent describes a gate structure that includes the ohmic layer and metal wiring. The ohmic layer is created using tungsten silicide, which consists of tungsten and silicon in a specific atomic ratio. The tungsten silicide is produced in a chamber using a reaction gas that includes both tungsten and silicon source gases. This innovative approach aims to reduce resistance in conductive structures, enhancing their overall performance.
