Thermal Stress-Aware CMOS–SRAM Partitioning in Sequential 3-D Technology

Abstract
This article explores the feasibility of high-temperature annealing for top-tier devices in a sequential 3-D (Seq3D) technology. Thermally stable bottom-tier device and interconnect design guidelines are provided. CMOS-SRAM partitioning is proposed to achieve performance gain from Seq3-D. The implications of thermally stable Seq3-D on system-level performance are evaluated. Seq3-D wafer and die cost of ownership are estimated.
