Latest Patents

One of Chao-Hu Liang's latest patents is a method of reducing charging damage to integrated circuits during semiconductor manufacturing. This patent describes an integrated circuit die that includes a first device region, a second device region, and a non-active region. A first implant mask is formed over the semiconductor substrate, covering the second device region and the non-active region while exposing the first device region. Dopant species are implanted into the exposed semiconductor substrate within the first device region to create first doping regions. Additionally, a second implant mask is formed, covering the first device region while exposing the second device region and a portion of the non-active region, allowing for the implantation of dopant species into the second active device region.

Another patent by Liang also focuses on reducing charging damage during semiconductor manufacturing. This patent involves a semiconductor substrate with an integrated circuit die area surrounded by a scribe lane. Within this area, a first trench isolation region and a second trench isolation region are formed. The first trench isolation region isolates a first active device region from a second active device region, while the second trench isolation region includes trench dummy features to reduce loading effects. A first gate electrode is formed on the first active device region, and a second gate electrode is formed on the second active device region, followed by an ion implantation process to implant dopant species into the second active device region.
