Patent number: 12113090Abstract: A method of fabricating a semiconductor device includes receiving a device substrate; forming an interconnect structure on a front side of the device substrate; and etching a recess into a backside of the device substrate until a portion of the interconnect structure is exposed. The recess has a recess depth and an edge of the recess is defined by a sidewall of the device substrate. A conductive bond pad is formed in the recess, and a first plurality of layers cover the conductive bond pad, extend along the sidewall of the device substrate, and cover the backside of the device substrate. The first plurality of layers collectively have a first total thickness that is less than the recess depth. A first chemical mechanical planarization is performed to remove portions of the first plurality of layers so remaining portions of the first plurality of layers cover the conductive bond pad.Type: GrantFiled: August 4, 2023Date of Patent: October 8, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chin-Wei Liang, Sheng-Chau Chen, Hsun-Chung Kuang, Sheng-Chan Li

Publication number: 20240316724Abstract: Some implementations herein describe a chemical-mechanical planarization tool including a polishing pad. The chemical-mechanical planarization tool including the polishing pad may perform a polishing operation to a semiconductor substrate. The polishing operation may generate, along a perimeter of the semiconductor substrate, a roll-off profile that satisfies a threshold. The polishing pad includes two or more regions, where each region includes a different pad surface pattern. Each region including a different pad surface pattern may correspond to a different polishing rate. Techniques using the polishing pad having such zone and pad surface pattern combinations allow for a focused and a controlled polishing of the semiconductor substrate, including along the perimeter of the semiconductor substrate to tightly control the roll-off profile.Type: ApplicationFiled: March 21, 2023Publication date: September 26, 2024Inventors: Hau-Yi HSIAO, Kuo-Ming WU, Sheng-Chau CHEN

Publication number: 20240312906Abstract: A sealing layer is formed around a contact structure of a resistor in a semiconductor device. The sealing layer fills in and occupies areas around the contact structure in which an overhang of a hard mask layer occurs as a result of lateral etching of the contact structure during formation of the contact structure. The sealing layer may include a material that can be selectively deposited on sidewalls of the contact structure and not on other layers and/or structures in the semiconductor device. The sealing layer may reduce the likelihood of void formation, in a dielectric layer, that might otherwise occur due to the overhang of the hard mask layer. The reduced likelihood of void formation may enable the dielectric layer to fully fill in the areas around the resistor in the semiconductor device, thereby increasing the structural integrity of the semiconductor device.Type: ApplicationFiled: March 17, 2023Publication date: September 19, 2024Inventors: Chung-Liang CHENG, Guanyu LUO, Sheng-Chan LI, Sheng-Chau CHEN
