Latest Patents

One of Yu-Shu Cheng's latest patents is a manufacturing method of a semiconductor device that includes a floating gate and a control gate. This method provides a unique approach by forming a tunneling dielectric layer, floating gates on the tunneling dielectric layer, an ONO layer on the floating gates, and control gates on the ONO layer. Notably, this method avoids the use of reactive-ion etching (R.I.E.), which prevents damage to the floating and control gates from high-density plasma. This innovation significantly reduces charge trapping in the floating gates, thereby improving data storage reliability.

Another significant patent by Cheng is for a semiconductor device and its manufacturing method. This device comprises a substrate, multiple floating gates, a tunneling dielectric layer, several control gates, and an ONO layer. The design ensures that the floating gates are positioned on the substrate, with the tunneling dielectric layer situated between the substrate and each floating gate. The control gates are placed on the floating gates, while the ONO layer is located on the sidewalls of each control gate and between the control gates and floating gates.
