Latest Patents

S K Lee's latest patents include innovative designs for gate structures and insulation systems. One of his patents, titled "Gate structures having sidewall spacers using selective deposition and method of forming the same," discloses gate stacks with sidewall spacers that have improved profiles to suppress or eliminate void formation during gap-filling. This invention involves forming a gate dielectric layer on a semiconductor substrate, followed by the creation of a gate stack with a sidewall. The process includes selectively depositing a liner over the gate stack, resulting in a thinner liner on the capping nitride layer compared to the conductive layer. A nitride spacer is then formed over the liner, and a PMD layer is created to fill gaps between adjacent gate stacks, ensuring a structure that is substantially free of voids.

Another notable patent is "Semiconductor integrated circuit with an insulation structure having reduced permittivity." This invention features a first insulating layer overlying a semiconductor substrate, with multiple conductive paths disposed thereon. Each conductive path is partially overlapped by a second insulating layer, while a third insulating layer with air gap ports forms air gaps between adjacent conductive paths. A passivation layer seals the air gap ports, creating an effective insulation structure for semiconductor integrated circuits.
