Latest Patents

Song’s recent patent work includes methods for forming and operating semiconductor devices. One disclosed device uses active pillars arranged on a semiconductor substrate, upper interconnections connecting the pillars, and lower interconnections crossing the upper interconnections. Word lines and data-storage patterns are also positioned among the pillars, forming an architecture for semiconductor memory.

Another patent describes a selective disposable spacer technique for manufacturing semiconductor integrated circuits. The method forms gate patterns with spaces of different widths, creates impurity regions beneath those spaces, and uses insulation spacers to control which regions are exposed. A wet-etching step enlarges the opening over one impurity region before an interlayer insulating layer is formed.
