Latest Patents

One of Jun-Sik Hong's latest patents is focused on methods for forming DRAM devices that include protective patterns. This patent describes a process where a first interlayer dielectric is formed on a semiconductor substrate, followed by the creation of a contact pad that connects to the substrate. A bitline is then formed on the first interlayer dielectric, ensuring it does not contact the contact pad. The process continues with the formation and planarization of a second interlayer dielectric, which exposes the top of the bitline. A protective layer is applied to the entire surface of the resultant structure, and a sacrificial layer is formed on top of the protective layer. This layer, along with the protective layer and the second interlayer dielectric, is patterned to create a bottom electrode contact hole that exposes the contact pad. Finally, a conductive layer is formed and planarized to create a bottom electrode contact plug that fills the hole.

Another significant patent involves the method of fabricating a recess channel array transistor using a mask layer with high etch selectivity concerning a silicon substrate. This method allows for the etching of the silicon substrate and an isolation insulating layer to form a recess channel trench. After forming a gate insulating layer and a recess gate stack on the trench, a source and drain are created in the silicon substrate adjacent to the recess gate stack. This innovative approach enables better control over the depth of the recess channel trench while maintaining good etching uniformity.
