Publication number: 20240128216Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.Type: ApplicationFiled: January 4, 2023Publication date: April 18, 2024Inventors: Hao-Lin Yang, Kuan-Chieh Huang, Wei-Cheng Hsu, Tzu-Jui Wang, Ching-Chun Wang, Hsiao-Hui Tseng, Chen-Jong Wang, Dun-Nian Yaung

Publication number: 20210339338Abstract: A laser cutting method for a wafer is provided. First, an active side of a wafer is cut by a laser to form multiple cutting grooves so that the thicker and harder layer of the integrated circuit on the active side is cut. Then the stealth laser is used to cut the backside of the wafer by aligning the beams of the stealth laser with the cutting grooves. Therefore, the cutting grooves easily extend to the backside of the wafer and penetrate through the wafer to dice the wafer into multiple independent chips.Type: ApplicationFiled: August 19, 2020Publication date: November 4, 2021Applicant: Powertech Technology Inc.Inventors: Chui-Liang CHIU, Kun-Chi HSU, Chin-Ta WU, Ching-Lin TSENG, Chia-Wei LIN, Jentung Tseng

Patent number: 7081645Abstract: A SMD-type LED with high heat dissipation efficiency and high power includes a base with a post arranged and integrated on the center thereof and a slot on top of the post. At least one contact hole is arranged on bottom of the base for connecting with an external heat sink so as to achieve better heat dissipation. The slot is used for accommodating a LED chip that is electrically connected with a circuitry extension device through two electrical contacts. The LED chip is electrically connected with the circuitry extension device directly while it also connects with the base for heat dissipation, thus the structure for electricity conduction is separated from the structure for heat dissipation.Type: GrantFiled: March 14, 2005Date of Patent: July 25, 2006Assignee: Bright Led Electronics Corp.Inventors: Yen Cheng Chen, Ching Lin Tseng, Sher Chain Wei, Ming Li Chang
