Patent number: 7153725Abstract: A method for fabricating a semiconductor package with a substrate in a strip format is provided. Semiconductor devices are attached in a strip format to the substrate, and a thermal interface material is applied to the semiconductor devices. A flat panel heat spreader is attached to each semiconductor device. The semiconductor devices are encapsulated with open encapsulation, leaving the surface of the flat panel heat spreader opposite the substrate externally exposed. Individual semiconductor packages are then singulated from the strip format.Type: GrantFiled: January 27, 2004Date of Patent: December 26, 2006Assignee: ST Assembly Test Services Ltd.Inventors: Tie Wang, Virgil Cotoco Ararao, Il Kwon Shim, Sheila Marie L.

Patent number: 7087458Abstract: A method for joining a semiconductor integrated circuit (IC) chip in a flip chip configuration, via pillar bump, to solderable metal contact pads, leads or circuit lines on the ciruitized surface of a chip carrier, as well as the resulting chip package, are disclosed. The semiconductor device is attached to the substrate via no flow underfill under thermal compression bonding. Integration of this structure and assembly method enables to incorporate low coefficient of thermal expansion (CTE) no flow underfill and achieve high assembly yield, especially for lead free bumps. The present invention provides a solution for a flip chip package with fine pitch, high pin count and lead free requirements.Type: GrantFiled: October 30, 2002Date of Patent: August 8, 2006Assignee: AdvanPack Solutions Pte. Ltd.Inventors: Tie Wang, Ping Miao, Chun Sing Colin Lum, Yixin Chew

Patent number: 6467676Abstract: An improved underfill adhesive encapsulant with fluxing activities containing an epoxy resin or a mixture of epoxy resin. An anhydride is used as the curing agent to harden the epoxy resin. A hydroxyl-containing fluxing precursor compound is added to the encapsulant composition to react with the anhydride curing agent to produce an active fluxing agent under typical reflow conditions. The use of a fluxing precursor gives improved reliability compared to conventional fluxing agents used in existing no-flow underfill encapsulants. A suitable catalyst such as imidazole, imidazole derivative or metal acetylacetonate is provided in the present encapsulant at concentrations that give good curing kinetics. A thermoplastic is optionally included to allow the cured encapsulant to be reworked.Type: GrantFiled: September 21, 2000Date of Patent: October 22, 2002Assignee: Advanpack Solutions PTE Ltd.Inventor: Tie Wang

Patent number: 6365435Abstract: In a no-flow underfill process 400, a substrate 10 is heated to an elevated temperature prior to dispensing underfill 5 thereon. The underfill 5 flows more readily over mask portions 20 and conductors 25 on the substrate 10, filling in spaces between the conductors 25 and the masking portions 20, thereby preventing air from being trapped thereabout. In addition, when a bumped die 40 is heated during placement on the substrate 10 with the underfill 5 therebetween, the underfill 5 flows around bumps 45 more readily thereby preventing air from being trapped thereabout. The result is a flip chip semiconductor package having a lower void density.Type: GrantFiled: March 22, 2001Date of Patent: April 2, 2002Assignee: Advanpack Solutions PTE LTDInventors: Tie Wang, Colin Chun Sing Lum

Patent number: 6360583Abstract: A gas sensor deterioration monitor, particularly suited for use in an exhaust stream from an internal combustion engine. Under certain engine operating conditions, the output signal from the sensor is transformed through a Fourier Transformation into a frequency domain signal. Ratios of the magnitudes of certain odd and even harmonics are compared to corresponding reference values for a new sensor. Deviations beyond certain limits indicate a sensor that has deteriorated substantially.Type: GrantFiled: November 30, 1998Date of Patent: March 26, 2002Assignee: Ford Global Technologies, Inc.Inventors: Richard E. Soltis, Tie Wang
