Latest Patents
Walsh's latest patents include the Vertical Internally-Connected Trench Cell (V-ICTC) and a formation method for semiconductor memory devices. This dynamic random access memory (DRAM) device features a vertical transistor and an internally-connected strap (ICS) that connects the transistor to the capacitor. Notably, the ICS does not make direct contact with the substrate. The DRAM cell operates at a substantially lower cell capacitance than that required for a conventional buried strap trench (BEST) cell, without negatively impacting device performance. This lower cell capacitance extends the feasibility of deep trench capacitor manufacturing technology without necessitating new materials or processing methods. Additionally, the method of manufacturing the DRAM involves forming a very thin silicon layer on top of a deep trench cell while simultaneously creating an isolated layer that replaces a conventional collar. The formation of the silicon-on-insulator (SOI) by internal thermal oxidation (ITO) allows the device to be fully depleted.
Another significant patent is for a semiconductor device with a silicon-germanium (Si-Ge) layer containing a low resistance, tunable contact. This invention provides a semiconductor device where a low resistance, tunable contact is formed using a Si Ge (0 Career Highlights John Walsh is currently employed at Promos Technologies, Inc., where he continues to innovate in the semiconductor field.
