  • Publication number: 20240141553
    Abstract: A manufacturing process is described to evaluate and select raw semiconductor wafers in preparation for epitaxial layer formation. The manufacturing process first produces a single crystal ingot during which a seed pulling velocity and temperature gradient are closely controlled. The resulting ingot is vacancy-rich with relatively few self-interstitial defects. Selected wafers can advance to a high-temperature nitridation annealing operation that further reduces the number of interstitials while increasing the vacancies. Substrates characterized by a high vacancy density can then be used to optimize an epitaxial layer deposition process.

  • Publication number: 20240134645
    Abstract: In various examples, a VPU and associated components may be optimized to improve VPU performance and throughput. For example, the VPU may include a min/max collector, automatic store predication functionality, a SIMD data path organization that allows for inter-lane sharing, a transposed load/store with stride parameter functionality, a load with permute and zero insertion functionality, hardware, logic, and memory layout functionality to allow for two point and two by two point lookups, and per memory bank load caching capabilities. In addition, decoupled accelerators may be used to offload VPU processing tasks to increase throughput and performance, and a hardware sequencer may be included in a DMA system to reduce programming complexity of the VPU and the DMA system. The DMA and VPU may execute a VPU configuration mode that allows the VPU and DMA to operate without a processing controller for performing dynamic region based data movement operations.
