摘要:
A non-volatile memory device includes a semiconductor layer including source and drain regions and a channel region between the source and drain regions; a tunneling insulating layer on the channel region of the semiconductor layer; a charge storage layer on the tunneling insulating layer; a blocking insulating layer on the charge storage layer and including a first oxide layer with a first thickness, a high-k dielectric layer, and a second oxide layer with a second thickness different from the first thickness that are stacked sequentially on the charge storage layer; and a control gate on the blocking insulating layer.
摘要:
A method of forming a flash memory device can include forming a tunneling oxide film on a semiconductor substrate, forming a charge storing layer on the tunneling oxide film, forming a first blocking oxide film on the charge storing layer at a first temperature, forming a second blocking oxide film on the first blocking oxide film at a second temperature higher than the first temperature, and forming a gate electrode on the second blocking oxide film.
