Latest Patents

Fu-Ying Chiu holds a patent for a method that improves polysilicon FET gate electrodes. This method involves creating composite sidewall spacers that enhance the structural integrity of the gate electrodes. The process begins with the formation of polysilicon gate electrodes on a substrate, followed by the deposition of a trapezoidal-shaped SiO₂ stress-release layer. A Si₃N₄ layer is then deposited and plasma etched back, utilizing the SiO₂ layer as an etch-endpoint-detect layer. This innovative approach protects the source and drain areas from plasma etch damage, which can lead to high leakage currents. The method ensures that the SiO₂ layer is preserved during the etching process, resulting in more reliable contacts without degrading the FET performance.
