Latest Patents

Yongseok Cho's latest patents include an integrated circuit device and a method of manufacturing the same. This integrated circuit device features a channel layer within a channel hole that penetrates a conductive line and an insulating layer. It also includes a charge trap pattern situated between the conductive line and the channel layer, as well as a dummy charge trap pattern located between the insulating layer and the channel layer. The manufacturing process involves forming a channel hole that penetrates both an insulating layer and a mold layer, followed by creating a mold indent connected to the channel hole. A preliminary dielectric pattern is formed in the mold indent, which is then oxidized to create a first blocking dielectric pattern. A charge trap layer is subsequently formed in the channel hole, and the mold layer is removed to create a conductive space. Portions of the charge trap layer are then removed to establish charge trap patterns and dummy charge trap patterns.

Another notable patent is for a semiconductor device that incorporates a sacrificial layer pattern with concave sidewalls. This method of fabrication involves leaving portions of sacrificial layers intact, rather than completely removing them. This innovative approach enhances the reliability of the semiconductor device and simplifies the manufacturing process.
