Publication number: 20210391281Abstract: Techniques for reducing warpage for microelectronic packages are provided. A warpage control layer or stiffener can be attached to a bottom surface of a substrate or layer that is used to attach the microelectronics package to a motherboard. The warpage control layer can have a thickness approximately equal to a thickness of a die of the microelectronics package. A coefficient of thermal expansion of the warpage control layer can be selected to approximately match a CTE of the die. The warpage control layer can be formed from an insulating material or a metallic material. The warpage control layer can comprise multiple materials and can include copper pillar segments to adjust the effective CTE of the warpage control layer. The warpage control layer can be positioned between the microelectronics package and the motherboard, thereby providing warpage control without contributing to the z-height of the microelectronics package.Type: ApplicationFiled: August 26, 2021Publication date: December 16, 2021Applicant: INTEL CORPORATIONInventors: ERIC J. LI, GUOTAO WANG, HUIYANG FEI, SAIRAM AGRAHARAM, OMKAR G. KARHADE, NITIN A. DESHPANDE

Patent number: 9633937Abstract: The electronic package includes a substrate and an electronic component mounted to a surface of the substrate. An interposer is mounted to the surface of the substrate such that the interposer surrounds the electronic component and is electrically connected to the substrate. An over-mold covers the electronic component. In other forms, the example electronic package may be incorporated into an electronic assembly. The electronic assembly further includes a second electronic component mounted to the interposer. As an example, the second electronic component may be mounted to the interposer using solder bumps. It should be noted that any technique that is known now, or discovered in the future, may be used to mount the second electronic component to the interposer.Type: GrantFiled: December 16, 2014Date of Patent: April 25, 2017Assignee: Intel CorporationInventors: Huiyang Fei, Prasanna Raghavan
