Patent number: 12131946Abstract: The present invention relates to a method of forming contact holes of a CMOS device and a method of making a CMOS device. Because a carbon cap layer or a carbon rich layer is formed on a etching stop layer, when etching reaches the etching stop layer with less depth, great polymer protecting the etching stop layer from etching will be formed in the etching stop layer. As such, when etching reaches the contact holes with more depth, the contact holes with less depth may be protected from over-etching until etching the contact holes with more depth is finished. Over-etching may be avoided, and meanwhile the contact holes with more depth may be fully etched to avoid from under-etching.Type: GrantFiled: January 25, 2022Date of Patent: October 29, 2024Assignee: SiEn (QingDao) Integrated Circuits Co., Ltd.Inventors: Min-Hwa Chi, Zhaosheng Meng, Xian Zhang

Patent number: 9997617Abstract: Embodiments disclosed in the detailed description include metal oxide semiconductor (MOS) isolation schemes with continuous active areas separated by dummy gates. A MOS device includes an active area formed from a material with a work function that is described as either an n-metal or a p-metal. Active components are formed on this active area using materials having a similar work function. Isolation is effectuated by positioning a dummy gate between the active components. The dummy gate is made from a material having an opposite work function relative to the material of the active area. For example, if the active area was a p-metal material, the dummy gate would be made from an n-metal, and vice versa.Type: GrantFiled: March 13, 2013Date of Patent: June 12, 2018Assignee: QUALCOMM IncorporatedInventors: Bin Yang, Xia Li, Periannan Chidambaram
