Publication number: 20240059712Abstract: The disclosure relates to bifunctional KRAS-G12D-modulating compounds having the structure W-L-T, where W is a targeting group that binds specifically to KRAS-G12D protein, T is an E3-ligase binding group, and L is absent or is a bivalent linking group that connects W and T together via a covalent linkage. Compounds and pharmaceutical compositions thereof can promote degradation of the KRAS-G12D protein in a cell and are thus useful for treating, inhibiting, and preventing KRAS-G12D-associated diseases, disorders and conditions, including cancers.Type: ApplicationFiled: September 13, 2023Publication date: February 22, 2024Inventors: Jiasheng LV, Xiang JI, Gang WU, Bin ZONG, Qiguo ZHANG, Yanpeng WU, Xiangyang LI, Yuhui CHEN, Yongyue CHEN, Chuanhao HUANG, Xingwu ZHU, Xiaolin HE, Yao LIU, Yuhua ZHANG, Jian GE, Tianlun ZHOU, Xiangsheng YE, Xianqi KONG, Dawei CHEN

Patent number: 10276450Abstract: One aspect of the present disclosure is a method of fabricating metal gate by forming special layers in place of traditional TiN hard mask over the ILD0 layer to avoid ILD0 losses due to conventional ILD0 CMP. The method can comprise: after the ILD0 CMP, forming a first thin ashable film layer over the ILD0 layer; then forming a second thin dielectric layer over the first layer; during the aluminum CMP process for a first region (PMOS or NMOS), removing the second layer through polishing until the top surface of the first ashable film layer; and then removing first ashable film layer through an ashing method such as burning. In this way, ILD0 loss can be reduced during the first aluminum CMP step and thus can reduce initial height of ILD0, which in turn can reduce the height of initial dummy gate filled in the cavity.Type: GrantFiled: February 10, 2017Date of Patent: April 30, 2019Assignee: Shanghai Huali Microelectronics CorporationInventors: Tong Lei, Yongyue Chen, Haifeng Zhou

Patent number: 10038078Abstract: A novel plasma process is introduced as an improvement over conventional plasma processes during formation of spacers for FinFET devices. Under this novel plasma process, an oxide layer is grown over sidewall materials and low energy plasma gas is used for the over-etching of the corner areas of the sidewalls. The oxide layer can effectively protect the sidewall materials during the over-etching by the low energy plasma gas and thus to reduce the aforementioned CD losses introduced by the low energy plasma gas. This improved low energy plasma etching technique can protect the fin structure from CD losses as compared to the conventional low energy plasma process, and also avoid damaging fin silicon structure with reduced Si losses as compared to the conventional high energy plasma process.Type: GrantFiled: February 10, 2017Date of Patent: July 31, 2018Assignee: Shanghai Huali Microelectronics CorporationInventors: Hailan Yi, Tong Lei, Yongyue Chen
