Patent number: 11742253Abstract: An integrated circuit (IC) package that is to be incorporated into a computing device may include a metallization structure with circuits and/or other elements such as capacitors or inductors thereon. Pads for input/output (I/O) (or other) purposes may also be present at different locations on the metallization structure. Exemplary aspects of the present disclosure allow mold material to be placed over the circuits and/or other elements in readily-customizable configurations so as to allow placement of the I/O pads in any desired location on the metallization structure. Specifically, before the mold material is applied to the metallization structure, a mask material such as tape may be applied to portions of the metallization structure that contain I/O pads or otherwise have reasons to not have mold material thereon. The mold material is applied, and the mask material is removed, taking unwanted mold material with the mask material.Type: GrantFiled: December 3, 2020Date of Patent: August 29, 2023Assignee: QUALCOMM INCORPORATEDInventors: Sayok Chattopadhyay, Rajneesh Kumar, Srikanth Kulkarni

Patent number: 10056294Abstract: Semiconductor devices are described that employ techniques configured to control adhesive application between a substrate and a die. In an implementation, a sacrificial layer is provided on a top surface of the die to protect the surface, and bonds pads thereon, from spill-over of the adhesive. The sacrificial layer and spill-over adhesive are subsequently removed from the die and/or chip carrier. In an implementation, the die includes a die attach film (DAF) on a bottom surface of the die for adhering the die to the cavity of the substrate. The die is applied to the cavity with heat and pressure to cause a portion of the die attach film (DAF) to flow from the bottom surface of the die to a sloped surface of the substrate cavity.Type: GrantFiled: July 8, 2014Date of Patent: August 21, 2018Assignee: MAXIM INTEGRATED PRODUCTS, INC.Inventors: Vivek S.
