Publication number: 20230326894Abstract: In a bonding process of a flip chip bonding method, a chip is bonded to contact pads of a substrate by composite bumps which each includes a raiser, a UBM layer and a bonding layer. Before the bonding process, the surface of the bonding layer facing toward the substrate is referred to as a surface to be bonded. During the bonding process, the surface to be bonded is boned to the contact pad and become a bonding surface on the contact pad. The bonding surface has an area greater than that of the surface to be bonded so as to reduce electrical impedance between the chip and the substrate.Type: ApplicationFiled: December 9, 2022Publication date: October 12, 2023Inventors: Fei-Jain Wu, Sheng-Jen Wu, Hsueh-Shun Yeh

Patent number: 9177830Abstract: A manufacturing method of a substrate with a bump structure, a copper layer is formed on a semiconductor substrate, and a nickel layer is formed on the copper layer. A bump structure is composed of the copper layer and the nickel layer, wherein the hardness of the bump structure after annealing process depends on the thickness of the nickel layer to meet the user's demand. The hardness of the bump structure meets the user's demand prevents a glass substrate from cracking when the substrate with the bump structure is bonded with the glass substrate.Type: GrantFiled: October 31, 2014Date of Patent: November 3, 2015Assignee: CHIPBOND TECHNOLOGY CORPORATIONInventors: Fei-Jain Wu, Tsang-Sheng Liao, Ching-Yi Huang, Chun-Te Lee

Publication number: 20020180064Abstract: The present invention relates to a wafer level package structure with a metal protection layer, and more particularly, to a wafer level package structure with a metal protection layer which is made of titanium, nickel, chromium or alloy thereof. The metal protection layer is adopted to prevent the substrate from being damaged by metal solder bumps. The metal protection layer also contributes to heat conduction and heat dissipation. Moreover, the metal protection layer is acid and alkali resistant and electromagnetic interference (EMI) resistant. The present invention improves the reliability of the IC component effectively.Type: ApplicationFiled: March 28, 2002Publication date: December 5, 2002Applicant: Chipbond Technology CorporationInventors: Lu-Chen Hwan, Fei-Jain Wu

Patent number: 5042688Abstract: An apparatus for optically controlling the volume of adhesive extruded from an orifice. A camera continuously monitors the adhesive discharged from the orifice; this adhesive is not applied to the target area until its volume is within preestablished limits. When the volume of adhesive is visually determined to be acceptable it is then applied to the target area. The camera is used again, to confirm the proper amount of adhesive has been applied to the target area by measuring the volume of adhesive remaining on the orifice after contacting the target area.Type: GrantFiled: November 15, 1989Date of Patent: August 27, 1991Assignee: Micro Robotics Systems Inc.Inventors: Nilendu Srivastava, Fei-Jain Wu, Michael J.
