Latest Patents

Sang S Kim's latest patents showcase his innovative approaches to semiconductor fabrication. The first patent is a Method and Structure for Isolating Integrated Circuit Components and/or Semiconductor Active Devices. This method details the formation of a field oxide or isolation region in a semiconductor die. This involves a nitride layer patterned over an oxide layer, which is subsequently etched to create nearly vertical sidewalls. The process results in a unique substrate recess with a sloped surface that significantly reduces oxide encroachment, showcasing a substantial improvement over non-sloped techniques. The ideal slope for the substrate sidewall is approximately 50°-80°.

His second patent, Method for Forming Dielectrically Isolated Semiconductor Devices, revolves around creating dielectrically isolated devices on a semiconductor substrate. In this method, an epitaxial layer is cultivated on a wafer with a thin buried oxide layer. Trench regions are then etched down to the oxide layer, where a dielectric isolation layer is introduced. The semiconductors are selectively regrown within the trenches, allowing for efficient formation of semiconductor devices with effective isolation.
