Non-volatile semiconductor memory devices

Abstract:

A non-volatile memory device includes a tunneling insulating layer on a semiconductor substrate, a charge storage layer, a blocking insulating layer, and a gate electrode. The charge storage layer is on the tunnel insulating layer and has a smaller band gap than the tunnel insulating layer and has a greater band gap than the semiconductor substrate. The blocking insulating layer is on the charge storage layer and has a greater band gap than the charge storage layer and has a smaller band gap than the tunnel insulating layer. The gate electrode is on the blocking insulating layer.

Abstract(Chinese):

非易失性存储器件包括在半导体衬底上的隧道绝缘层，电荷存储层，阻挡绝缘层和栅电极。电荷存储层位于隧道绝缘层上，并且具有比隧道绝缘层更小的带隙，并且具有比半导体衬底更大的带隙。阻挡绝缘层位于电荷存储层上，并且具有比电荷存储层更大的带隙，并且具有比隧道绝缘层更小的带隙。栅电极位于阻挡绝缘层上。
