Latest Patents

Liang Zhao's latest patents include a semiconductor structure and a method for forming this structure. The method involves providing a substrate that includes a first region and a second region. It also includes forming an insulating layer on the substrate and etching a portion of this layer in the second region. The insulating layer in the first region is configured as a first insulating layer, while the remaining portion in the second region is configured as a second insulating layer. Additionally, a first barrier layer covers the first insulating layer, and a second barrier layer covers the second insulating layer. The process continues with etching the first barrier layer and a portion of the second barrier layer to create a through hole in the first insulating layer and a hole segment in the second barrier layer, followed by the removal of both barrier layers.

Another notable patent is for a semiconductor device that includes a substrate with a memory array region and a peripheral region. This device features a first interlayer insulation layer and a second interlayer insulation layer formed on the substrate. The columnar capacitor array, which consists of columnar capacitors arranged at intervals, is formed in these insulation layers within the memory array region. A contact structure is also established in the first and second interlayer insulation layers in the peripheral region.
