A method of forming a contact on a semiconductor device is provided. First, a substrate is provided. A plurality of gate structures defined by a plurality of word lines in a first direction, and a plurality of diffusion regions covered by a first dielectric layer in a second direction are provided over the substrate. The gate structures located underneath the word lines and isolated by the diffusion regions. Then, an etching stop layer is formed. The etching stop layer and the first dielectric layer have different etching selectivity. A second dielectric layer is formed over the substrate. Furthermore, a plurality of contact holes to the diffusion regions between the word lines are formed by using the etching stop layer as a self-aligned mask.

A non-volatile memory structure including a substrate, stacked patterns and stress patterns is provided. The stacked patterns are disposed on the substrate. Each of the stacked patterns includes a charge storage structure and a gate from bottom to top. Here, the charge storage structure at least includes a charge storage layer. The stress patterns are disposed on the substrate between the two adjacent stacked patterns, respectively.

A system, method, and layout for a semiconductor integrated circuit device allows for improved scaling down of various back-end structures, which can include contacts and other metal interconnection structures. The resulting structures can include a semiconductor substrate, a buried diffusion region formed on the semiconductor substrate, and at least one of a silicide film, for example tungsten silicide (WSix), and a self-aligned silicide (salicide) film, for example cobalt silicide (CoSi) and/or nickel silicide (NiSi), above the buried diffusion (BD) layer. The semiconductor integrated circuit can also include a memory gate structure formed over at least a portion of the contact layer.
