This thesis focuses on carrying out a parametric study of stacking memory and the logic processor on the same substrate. In present technologies, logic processor and memory packages are located side-by-side on the board or they are packaged separately and then stacked on top of each other (Package-on-package [PoP]). Mixing memory and logic processor in the same stack has advantage and challenges, but requires the integration ability of economies-of-scale. The technology needed for packaging memory and logic dice on the same substrate is completely different as compared to packaging only memory dice or logic dice, or, packaging memory and logic separately and creating a single functional package [PoP]. Geometries needed were generated by using Pro/EngineerRTM Wildfire(TM) 2.0 as a Computer-Aided-Design (CAD) tool and were transferred to ANSYSRTM Workbench(TM) 10.0, where meshed analysis was conducted. Package architectures evaluated were rotated stack, staggered stack utilizing redistributed pads, and stacking with spacers, while all other parameters were held constant. The values of these parameters were determined to give a junction temperature of 100°C, which is an unacceptable value due to wafer level electromigration. A discussion is presented as to what parameters need to be adjusted in order to meet the required thermal design specification. In that light, a list of solutions consisting of increasing the heat transfer co-efficient on top of the package, the use of underfill, improved thermal conductivity of the PCB, and the use of a copper heat spreader were evaluated. Results are evaluated in the light of market segment requirements. (Abstract shortened by UMI.).

The emerging three-dimensional (3D) chip architectures, with their intrinsic capability of reducing the wire length, promise attractive solutions to reduce the delay of interconnects in future microprocessors. 3D memory stacking enables much higher memory bandwidth for future chip-multiprocessor design, mitigating the "memory wall" problem. In addition, heterogenous integration enabled by 3D technology can also result in innovative designs for future microprocessors. This book first provides a brief introduction to this emerging technology, and then presents a variety of approaches to designing future 3D microprocessor systems, by leveraging the benefits of low latency, high bandwidth, and heterogeneous integration capability which are offered by 3D technology.

This fourth volume of the landmark handbook focuses on the design, testing, and thermal management of 3D-integrated circuits, both from a technological and materials science perspective. Edited and authored by key contributors from top research institutions and high-tech companies, the first part of the book provides an overview of the latest developments in 3D chip design, including challenges and opportunities. The second part focuses on the test methods used to assess the quality and reliability of the 3D-integrated circuits, while the third and final part deals with thermal management and advanced cooling technologies and their integration.

The large scale integration and planar scaling of individual system chips is reaching an expensive limit. If individual chips now, and later terrabyte memory blocks, memory macros, and processing cores, can be tightly linked in optimally designed and processed small footprint vertical stacks, then performance can be increased, power reduced and cost contained. This book reviews for the electronics industry engineer, professional and student the critical areas of development for 3D vertical memory chips including: gate-all-around and junction-less nanowire memories, stacked thin film and double gate memories, terrabit vertical channel and vertical gate stacked NAND flash, large scale stacking of Resistance RAM cross-point arrays, and 2.5D/3D stacking of memory and processor chips with through-silicon-via connections now and remote links later. Key features: Presents a review of the status and trends in 3-dimensional vertical memory chip technologies. Extensively reviews advanced vertical memory chip technology and development Explores technology process routes and 3D chip integration in a single reference
