Postdoctoral Researcher Architecture and Circuit Exploration for 3D Monolithic Logic Integration
What you will do
- The goal is to have a 1 process step/mask-set based flow which can generate a wide N-bit digital programmable microprocessor, similar like 3D NAND Flash implementation achieves now. But it is highly non-obvious to generalize the NAND solution to a programmable logic core because this requires a pure planar metal, active and gate material layout without any crossings. No solution has been found for that yet in literature.
- In order to achieve a large enough market volume to motivate the huge NRE costs, the application domain where such a programmable microprocessor is focused on should be very broad. That creates even more challenges for the process step/integration flow and no-crossing layout scheme. It also requires to support advanced microprocessor features such as support for subword parallelism/SIMD and more complex ALU instructions.
- We need to pass instruction bits through the vertical monolithic stack to program the ALU bit slices and that is again highly non-obvious. Several innovative technology solutions have to be explored to create such a "vertical delay line".
- We should not only have a solution for the logic core, but we have to add foreground memory, background data memory, instruction storage and an I/O interface. The standard/conventional circuit and architecture techniques for these crucial components have to be adapted to fit into the monolithic 3D integration flow. That is again highly non-obvious.
