Latest Patents

One of Ji Hyung Yune's latest patents is a method for fabricating a semiconductor device. This method includes chemical-mechanical polishing to planarize an insulating interlayer deposited on a lower pattern. The insulating interlayer is polished using a surfactant, and the chemical-mechanical polishing involves at least two separate polishing steps with different fluxes of the surfactant. The first polishing step is performed to touch up the upper side of the insulating layer, while the second polishing step is conducted to planarize the insulating interlayer after completing the first step.

Another notable patent is for a flash memory cell and the method for manufacturing the same. In this invention, an active region and a trench region are formed on a semiconductor substrate. The trench region is filled with a dielectric material to create an isolation layer. Oxide and polysilicon layers are then formed on the substrate. A second polysilicon layer, a second oxide layer, and a first polysilicon layer are patterned to create multiple gate lines. Deep ion implantation is performed in a deep portion of the active region using a self-aligned source mask, which allows for precise exposure and implantation in the common source region.
