Publication number: 20250391705Abstract: High dielectric constant (high-k) passivation layers are omitted from a back side surface of a device layer of a semiconductor die in a semiconductor die package. Instead, a hard mask layer is formed directly on the back side surface of the device layer, and the hard mask layer is patterned and used to form one or more elongated conductive structures (e.g., one or more through substrate vias (TSVs)) through the device layer. The high-k passivation layers may be omitted for particular types of device layers and/or for particular types of integrated circuit devices, thereby reducing the complexity, time, and cost for forming the semiconductor die package.Type: ApplicationFiled: June 20, 2024Publication date: December 25, 2025Inventors: Harry-HakLay CHUANG, Wen-Tuo HUANG, Wei-Cheng WU, Yu-Ling HSU, Yu-Chun CHANG, ShihKuang YANG, Pai Chi CHOU, Che-Wei CHEN

Patent number: 9590105Abstract: A semiconductor device and methods of formation are provided. The semiconductor device includes a first metal alloy over a first active region of a fin and a second metal alloy over a second active region of the fin. A conductive layer is over a channel region of the fin. A semiconductive layer is over the conductive layer. The conductive layer over the channel region suppresses current leakage and the semiconductive layer over the conductive layer reduces electro flux from a source to a drain, as compared to a channel region that does not have such a conductive layer or a semiconductive layer over a conductive layer. The semiconductor device having the first metal alloy as at least one of the source or drain requires a lower activation temperature than a semiconductor device that does not have a metal alloy as a source or a drain.Type: GrantFiled: April 7, 2014Date of Patent: March 7, 2017Assignees: National Chiao-Tung University, Taiwan Semiconductor Manufacturing Company LimitedInventors: Chao-Hsin Chien, Cheng-Ting Chung, Che-Wei Chen
