Patent number: 12278172Abstract: In order to relieve the stress on the substrates in a 3D stacked electronic assembly, a substrate frame is divided into a plurality of frame sections that are separated by spaces between the frame sections. These separations allow the substrates to expand/contract in response to temperature variations and other environmental conditions, and generally allow the substrates to move in one or more axial directions. The separations between the substrate portions are design-specific for each substrate design. The placement of IC packages on either side of the substrate is analyzed to identify areas of maximal warpage through physical measurements, physical model simulations, or using a trained neural network. The spaces in the substrate frame are then be placed next to or aligned with the areas of maximal warpage to reduce the stress on the substrate.Type: GrantFiled: June 28, 2022Date of Patent: April 15, 2025Assignee: Applied Materials, Inc.Inventors: Akash Agrawal, Prashanth Ganeshbaabu

Structural features and stack configurations are provided for memory modules and 3DICs to reduce defects in vertically stacked dies. Example processes alleviate warpage stresses between a thicker top die and direct bonded dies beneath it, for example. An etched surface on the top die may relieve warpage stresses.

An array of cavities on a bonding surface can alleviate stress forces. One or more stress balancing layers may also be created on a side of the top die or between other dies to alleviate or counter warpage. Rounding of edges can prevent stresses and pressure forces from being destructively transmitted through die and substrate layers. These measures may be applied together or in combinations in a single package.Type: GrantFiled: February 27, 2024Date of Patent: April 8, 2025Assignee: ADEIA SEMICONDUCTOR BONDING TECHNOLOGIES INC.Inventors: Cyprian Emeka Uzoh, Rajesh Katkar, Thomas Workman, Guilian Gao, Gaius Gillman Fountain, Jr., Laura Wills Mirkarimi, Belgacem Haba, Gabriel Z.
