Publication number: 20250125309Abstract: Vertically stacked semiconductor devices and methods of fabrication thereof that include a first device structure bonded to a second device structure via bonding layers having compressible metal bonding structures. The compressible metal bonding structures may be fabricated using an electroless deposition (ED) process, and may be less dense with a greater degree of compressibility than equivalent materials deposited by related processes. Accordingly, mating pairs of metal bonding structures may have a degree of compliance that enables effective metal-to-metal contact during a subsequent bonding process. Recrystallization of the metal material during an annealing process may produce shrinkage of the metal material and the formation of void areas between the metal bonds and the surrounding dielectric layers, thereby reducing stress on the surrounding dielectric-to-dielectric interface.Type: ApplicationFiled: October 11, 2023Publication date: April 17, 2025Inventors: Kai-Hsiang Yang, Chin-Fu Kao, Amram Eitan, Shu-Cheng Lin

Patent number: 10185609Abstract: Approaches, techniques, and mechanisms are disclosed for improving data retention using a virtual timer. A memory controller may use a raw bit error rate (RBER) to find an equivalent temperature-accelerated data age of a data item. The data age is computed by using the initial RBER of virtual timing data (VTD) as a virtual write in time of the data item compared to a present time using the current RBER of the VTD. When the data age is determined to exceed a data retention threshold, a data refresh is performed on the data item at the memory block on the memory device. The data age may be stored as virtual timing data on the memory block.Type: GrantFiled: December 22, 2016Date of Patent: January 22, 2019Assignee: SMART Modular Technologies, Inc.Inventor: Shu-Cheng Lin
