Latest Patents

Choonghyun Lee holds a patent for "Vertical transport field effect transistors having different threshold voltages along the channel." This invention involves embodiments for vertical field effect transistors that feature varying threshold voltages along the channel. A vertical fin with a vertical channel is formed, where one end of the channel includes a doped layer. This doped layer causes the threshold voltage at that end to differ from the remainder of the vertical channel. Additionally, a source and a drain are formed, each coupled to opposite ends of the vertical fin, with gate material applied to the vertical channel.
