    摘要: A vertical type semiconductor device can include a vertical pillar structure that includes a channel pattern with an outer wall. Horizontal insulating structures can be vertically spaced apart from one another along the vertical pillar structure to define first vertical gaps therebetween at first locations away from the outer wall and to define second vertical gaps therebetween at the outer wall, where the second vertical gaps are wider than the first vertical gaps. Horizontal wordline structures can be conformally located in the first and second vertical gaps between the vertically spaced apart horizontal insulating structures, so that the horizontal wordline structures can be vertically thinner across the first vertical gaps than across the second vertical gaps.

    摘要: The device includes: a tunnel insulating layer, a charge trap layer; a blocking insulating layer; and a gate electrode sequentially formed on a substrate. The charge trap layer includes: plural trap layers comprising a first material having a first band gap energy level; spaced apart nanodots, each nanodot being at least partially surrounded by at least one of the trap layers, wherein the nanodots comprise a second material having a second band gap energy level that is lower than the first band gap energy level; and an intermediate blocking layer comprising a third material having a third band gap energy level that is higher than the first band gap energy level, formed between at least two of the trap layers. This structure prevents loss of charges from the charge trap layer and improves charge storage capacity.

    摘要: Manufacturing of a charge trap type memory device can include forming a tunnel insulating layer on a substrate. A charge-trapping layer can be formed on the tunnel insulating layer. A blocking layer can be formed on the charge-trapping layer. Gate electrodes can be formed on the blocking layer and divided by a trench. A portion of the charge-trapping layer aligned with the trench may be converted into a charge-blocking pattern with a vertical side profile by an anisotropic oxidation process.
