Floating gate having enhanced charge retention

Abstract:

A semiconductor device includes a source and a drain formed in a substrate, a tunneling dielectric formed on the substrate between the source and the drain, and a floating gate disposed over the tunneling dielectric having a band-gap energy less than the energy band-gap of silicon.

Abstract(Chinese):

半导体器件包括形成在衬底中的源极和漏极，形成在源极和漏极之间的衬底上的隧道电介质，以及设置在隧道电介质上的浮置栅极，其带隙能量小于能带隙能量的硅。
