Latest Patents

One of his latest patents is a method for making a semiconductor device with reduced spacing. This invention involves forming floating gates in two separate polysilicon deposition steps, resulting in distinct portions that enhance the device's performance. The first formed portions are strategically placed between isolation regions, and a thick insulator is created over these regions. The insulator is then patterned to leave fences, which are thinned through an isotropic etch process. This innovative approach allows for the formation of polysilicon sidewall spacers that become the second portion of the floating gate, significantly increasing capacitance and reducing the gate voltage required for programming and erasing.

Another significant patent by Singh is related to a semiconductor device structure and method for forming it. This invention features trenches of varying widths to maximize density while ensuring high-quality isolation. The wider trenches are lined with a high-quality grown oxide, which is crucial for achieving the desired isolation quality. Singh's method addresses potential issues with voids that can occur during the deposition of insulating material, ensuring that the aspect ratio remains within acceptable levels.
