Latest Patents

Among his latest patents is a method of fabricating a semiconductor device that includes a porous dielectric layer. This method involves sequentially stacking an interlayer insulating layer, a porous dielectric layer, a first mask layer, and a second mask layer on a substrate. The process includes etching the second mask layer to form preliminary mask patterns, followed by etching to create second mask patterns. The first mask layer is then etched using the second mask patterns as an etch mask to form first mask patterns. The porous dielectric layer is etched using the first mask patterns to create grooves, where interconnection patterns are formed. Notably, the porous dielectric layer comprises SiOCH, while the first mask layer consists of carbon-free silicon oxide (SiO).

Another significant patent involves a semiconductor device that includes a device isolation layer with multiple patterns. This device features a substrate with trenches that define an active pattern, including a first trench and a second trench of varying widths. The device isolation layer partially fills these trenches and includes multiple isolation patterns. The design ensures that the top surface of the second isolation pattern is elevated compared to the filling pattern beneath the word line.
