Latest Patents

Among his latest contributions to the field are two significant patents. The first is for a **Semiconductor Device Having First and Second Separation Trenches**. This invention features a silicon-on-insulator (SOI) substrate that includes a SOI layer, a buried oxide layer, and a support substrate. The design incorporates multiple first separation trenches, where each metal-oxide-semiconductor (MOS) transistor is surrounded by a first separation trench. Additionally, a second separation trench is formed, enclosing n-ply field trenches and multiple field regions, enhancing the connectivity of MOS transistors arranged in series for improved electrical performance.

His second notable patent is for an **EEPROM and EEPROM Manufacturing Method**. This patent involves a memory transistor with a uniquely shaped floating gate electrode that entirely encases the tunnel film and channel region while leaving a gap between the channel region and embedded layer. Furthermore, a control gate electrode is constructed on an interlayer insulating film above the floating gate, which is designed wider than the floating gate over the tunnel film but narrower above the channel region, thus optimizing memory operation.
