Latest Patents

Gadepally holds two patents that showcase his innovative approach. The first patent focuses on a method for enhancing the breakdown behavior of DMOST devices. This invention addresses the body to drain junction breakdown, which can be controlled to lower electric field gradients near the PN junction. The structure employed is specifically applied to a vertical DMOST, utilizing a tailored N type doping profile. By constructing a P-nu-N-N.sup.+ type diode structure, the avalanche breakdown voltage can be increased by up to 40% compared to conventional PN junction diodes.

The second patent involves a semiconductor memory device featuring a CMOS memory cell with a floating gate. This device incorporates an exponentially-profiled doping concentration across the source, drain, and channel regions. The design allows for significantly reduced write times compared to traditional devices, thanks to a tunnel 'window' created by reducing gate oxidation thickness over the channel near the drain.
