Patent number: 12046536Abstract: An integrated circuit package includes a first die and second die above a substrate, and a vapor chamber above at least one of the first and second die. A vapor space within the vapor chamber is separated into at least a first section and a second section. The first section may be over the first die, and the second section may be over the second die, for example. The structure separating the first and second sections at least partly restricts flow of vapor between the first and second sections, thereby preventing or reducing thermal cross talk between the first and second dies. In some cases, an anisotropic thermal material is above one of the first or second die, wherein the anisotropic thermal material has substantially higher thermal conductivity in a direction of a heat sink than a thermal conductivity in a direction of a section of the vapor chamber.Type: GrantFiled: April 30, 2019Date of Patent: July 23, 2024Assignee: Intel CorporationInventors: Je-Young Chang, James C.

Patent number: 10586779Abstract: Embodiments describe high aspect ratio and fine pitch interconnects for a semiconductor package, such as a package-on-package structure. In an embodiment, the interconnects are formed with a no-slump solder paste. In an embodiment, the no-slump solder paste is printed in an uncured state, and is then cured with a liquid phase sintering process. After being cured, the no-slump solder paste will not reflow at typical processing temperatures, such as those below approximately 400° C. According to embodiments, the no-slump solder paste includes Cu particles or spheres, a solder matrix component, a polymeric delivery vehicle, and a solvent. In an embodiment, the liquid phase sintering produces a shell of intermetallic compounds around the Cu spheres. In an embodiment, the sintering process builds a conductive metallic network through the no-slump solder paste.Type: GrantFiled: October 24, 2017Date of Patent: March 10, 2020Assignee: Intel CorporationInventors: Nachiket R.

Publication number: 20180286704Abstract: A process for applying an underfill material to a die is disclosed. A wafer is diced into a plurality of dies (without having any underfill film thereon) such that the dies have exposed bumps prior to an underfill process. Thus, the dies can be tested about their bump-sides because the bumps are entirely exposed for testing. The dies are then reconstituted bump-side up on a carrier panel in an array such that the dies are separated from each other by a gap. Underfill material (e.g., epoxy flux film) is then vacuum laminated to the carrier panel and the plurality of dies to encapsulate the dies. The underfill material is then cut between adjacent dies such that a portion of the underfill material covers at least one side edge of each die. The encapsulated dies are then removed from the carrier panel, thereby being prepared for a thermal bonding process to a substrate. Associated devices are provided.Type: ApplicationFiled: April 1, 2017Publication date: October 4, 2018Applicant: Intel CorporationInventors: Elizabeth M. Nofen, Arjun Krishnan, James C.
