Latest Patents

Ki-Hyung Lee's latest patents include a method of manufacturing a semiconductor device that features a one-time programmable (OTP) erasable and programmable read-only memory (EPROM) cell. This innovative device incorporates a plasma enhanced oxide (PEOX) film that covers the upper surface of a floating gate in a single poly OTP cell. The semiconductor device consists of a substrate with an OTP cell region, where a floating gate is formed to create an OTP cell transistor, and a main chip region, where a transistor gate is established. The PEOX film is strategically formed on both the OTP cell region and the main chip region, ensuring that it covers the floating gate in a closed state while maintaining a predetermined distance from the gate. Additionally, a silicon oxy nitride (SiON) film is interposed between the gate and the PEOX film in the main chip region.
