Patent number: 11955379Abstract: A metal adhesion layer may be formed on a bottom and a sidewall of a trench prior to formation of a metal plug in the trench. A plasma may be used to modify the phase composition of the metal adhesion layer to increase adhesion between the metal adhesion layer and the metal plug. In particular, the plasma may cause a shift or transformation of the phase composition of the metal adhesion layer to cause the metal adhesion layer to be composed of a (111) dominant phase. The (111) dominant phase of the metal adhesion layer increases adhesion between the metal adhesion layer.Type: GrantFiled: September 15, 2020Date of Patent: April 9, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Pei-Wen Wu, Chun-I Tsai, Chi-Cheng Hung, Jyh-Cherng Sheu, Yu-Sheng Wang, Ming-Hsing Tsai

Patent number: 10064484Abstract: A lift table includes a base unit having a supporting beam connected between two legs. An elongated member is connected to a first linking rod, a second linking rod and a third linking rod and is pivotably connected to the legs. The first linking rod, the second linking rod and the third linking rod are pivotable together with the elongated member relative to the legs and are, thus, pivotable relative to the base unit. A telescopic actuator includes two ends pivotably connected to the supporting beam and the second linking rod, respectively. A top board unit is pivotably connected to the first and third linking rods and includes a switch operable to actuate the actuator to proceed with a telescope movement, causing the first and third linking rods to pivot relative to the legs, thereby lifting or lowering the top board unit.Type: GrantFiled: August 22, 2017Date of Patent: September 4, 2018Assignee: Sing Bee Enterprise Co., Ltd.Inventor: Chi-Cheng Tsai
