Publication number: 20140061895Abstract: A multi-chip module and a method for manufacturing the multi-chip module that mitigates wire breakage. A first semiconductor chip is mounted and wirebonded to a support substrate. A spacer is coupled to the first semiconductor chip. A support material is disposed on the spacer and a second semiconductor chip is positioned on the support material. The second semiconductor chip is pressed into the support material squeezing it into a region adjacent the spacer and between the first and second semiconductor chips. Alternatively, the support material is disposed on the first semiconductor chip and a die attach material is disposed on the spacer. The second semiconductor chip is pressed into the die attach material and the support material, squeezing a portion of the support material over the spacer edges. Wirebonds are formed between the support substrate and the first and second semiconductor chips.Type: ApplicationFiled: November 11, 2013Publication date: March 6, 2014Applicant: Spansion LLCInventors: Yin Lye FOONG, Cheng Sim Kee, Lay Hong Lee, Mohamed Suhaizal Bin Abu-Hassan

Publication number: 20090051043Abstract: Systems, methods, and devices that facilitate stacking dies in a multi-die stack using die support mechanisms (DSMs) are presented. DSMs are employed to place a smaller die and attached wires underneath a larger die. DSMs can be placed on each side of the smaller die where the larger die overhangs when placed above the smaller die. The DSMs can be optimally sized to provide support to the larger die to reduce overhang and sagging, while providing a buffer region to protect the smaller die and associated wires. DSMs are employed to facilitate stacking dies that are the same or similar in size by placing a DSM between the dies. The DSM can be optimally sized to provide a buffer region to protect the wires bonded to the top side of the lower die from the upper die, while minimizing overhang to provide support to the upper die.Type: ApplicationFiled: August 21, 2007Publication date: February 26, 2009Applicant: SPANSION LLCInventors: Wai Loon Wong, Cheng Sim Kee, Nguk Chin Lai, Poh Huat Teh, Kwet Nam Wong, Nutcha Tapamnuay, Bharatwaj Ramakrishnan

Publication number: 20090001599Abstract: Systems, methods, and/or devices that facilitate stacking dies in a multi-die stack using film over wire and attaching a die to a substrate are presented. Film over wire (FOW) techniques can be employed to facilitate stacking dies that are the same or similar in size such that the wires bonded onto the lower die can be embedded in film used to attach the two dies. FOW techniques can also be employed to embed a smaller die and wires attached thereto in film underneath a larger die stacked on top of the lower die such that the larger die can be supported by the film in areas where the larger die would otherwise overhang. Die attach film can be utilized to facilitate attaching a die to a substrate such that all areas between the die and substrate are filled thereby reducing or eliminating delamination.Type: ApplicationFiled: June 28, 2007Publication date: January 1, 2009Applicant: SPANSION LLCInventors: Sally Foong, Tan Kiah Ling, Cheng Sim Kee, Seshasayee Gaddamraja, Yue Ho Foong

Publication number: 20080318364Abstract: Methods and systems of applying a plurality of pieces of die attach film to a plurality of singulated dice are provided. The method can involve making intervals between rows and columns of a plurality of pieces of die attach film. The interval can be made by expanding an underlaid expandable film on which the plurality of pieces of die attach film are placed or by removing portions of the die attach film between rows and columns of the plurality of pieces of die attach film. The method can further involve placing a plurality of singulated dice back side down on the plurality of pieces of die attach film.Type: ApplicationFiled: June 25, 2007Publication date: December 25, 2008Applicant: SPANSION LLCInventors: Sally Foong, Kiah Ling Tan, Cheng Sim Kee, Kwet Nam Wong, Yue Ho Foong
