Publication number: 20240071981Abstract: A method of fabricating a semiconductor structure includes the following steps. A semiconductor wafer is provided. A plurality of first surface mount components and a plurality of second surface mount components are bonded onto the semiconductor wafer, wherein a first portion of each of the second surface mount components is overhanging a periphery of the semiconductor wafer. A first barrier structure is formed in between the second surface mount components and the semiconductor wafer. An underfill structure is formed under a second portion of each of the second surface mount components, wherein the first barrier structure blocks the spreading of the underfill structure from the second portion to the first portion.Type: ApplicationFiled: November 1, 2023Publication date: February 29, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Mao-Yen Chang, Chih-Wei Lin, Hao-Yi Tsai, Kuo-Lung Pan, Chun-Cheng Lin, Tin-Hao Kuo, Yu-Chia Lai, Chih-Hsuan Tai

Publication number: 20130147870Abstract: A printing method for three-dimensional painting by UV digital printing device has acts of: First, preparing a printing device having a white print set and a color print set. Second, moving the printing device transversely from one side to the other side of an object for multiple times, wherein the two print sets respectively print on two adjacent zones. Third, moving the printing device longitudinally to next zone on the object. Fourth, repeating the second and third acts until the printing device moves over a last zone on the object. The printing device moves longitudinally after the printing device moves transversely to and fro to finish the height of a zone. Thus, the printing device completes all the heights and the colors in one time of longitudinal moving. Then printing consumes less time and the printing device therefore does not have to be orientated again.Type: ApplicationFiled: December 13, 2011Publication date: June 13, 2013Applicants: DIGITAL PHOTONICS CORPORATION, ANDERSON INDUSTRIAL CORP.Inventors: Awen YEH, Kai LIU, Jim LIU, Chen-Ying CHENG, Chih-Yi LAI, Mao-Feng TU

Patent number: 7731318Abstract: A pneumatic ink-jet system is applied in an inkjet printer and uses a negative pressure generator, which is designed according to the Bernoulli's Theory, with a stable airflow in a certain speed to generated stable pressure inside at least one inkpot and at least one print head. Therefore, the at least one print head is kept in an appropriate wet state and the quality of printing is enhanced. Moreover, a top surface of the ink inside the at least one inkpot can be controlled to be higher than the at least one print head, so the pneumatic ink-jet system can be applied in a large format inkjet printer.Type: GrantFiled: February 28, 2008Date of Patent: June 8, 2010Assignee: Digital Photonics CorporationInventors: Chi-Shi Liu, Chih-Yi Lai, Chun-Ying Cheng

Publication number: 20060036337Abstract: A cutting tool adjustment method is disclosed to lower a cutting tool on a transparent Mylar to produce an indentation before actual scribing operation, and then to pick up the image of the indentation, and then to use a numerical analysis method and the set formula to automatically calculate the correction angle and position and to adjust the angle and position of the cutting tool subject to the calculation result, and then to repeat the calculation and adjustment procedure if necessary. Thus, the cutting tool and its cutting edge can be accurately adjusted to the correct angle and position to obtain a precise indentation. Further, by means of the automatic adjustment procedure, the present invention saves much adjusting time, thereby improving the productivity.Type: ApplicationFiled: December 14, 2004Publication date: February 16, 2006Inventors: Kuei-Jung Chen, Sin-Len Tan, Chih-Yi Lai, Meng-Chun Chen

Patent number: 6871115Abstract: The integrity of control signals used to control a wafer handling robot is monitored by a monitor connected to various points of the robotic control system. The monitor includes a memory for storing data sets representing correct, reference characteristics of the control signals. The monitor samples control signals at various points in the control system and compares these sampled signals with the stored reference characteristics in order to determine whether a signal disparity exists. If a disparity exists, the monitor generates an error.Type: GrantFiled: October 11, 2002Date of Patent: March 22, 2005Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Kuo-Liang Huang, Enzo Kuo, Patrick Chen, Yuan-Chich Lin, Chih-Yi Lai, Chun-Hung Liu
