The advancements in AI technology have indeed driven improvements in processing units, and these improvements often extend to the overall fabrication process of semiconductor devices. The demand for more powerful and efficient hardware to support AI workloads has led to the development of specialized accelerators. Graphics Processing Units (GPUs), Tensor Processing Units (TPUs), High Bandwidth Memory (HBM) and other custom-designed chips are being used to accelerate specific AI computations. The fabrication of these specialized chips involves advanced semiconductor manufacturing processes.
Further, AI applications often require a mix of processing units optimized for different tasks. Heterogeneous integration involves combining different types of processing units, such as CPUs, GPUs, and accelerators, on a single chip or package. 3D chip stacking technologies have paved the path for improved performance, reduced latency, and increased overall system efficiency. Chips are stacked using various advanced packaging technologies, allowing multiple semiconductor dies to be vertically integrated. Stacking chips in this manner offers important advantages. Some common methods for stacking chips: Chip-on-Wafer-on-Substrate, Fan-Out Wafer-Level Packaging, and System-on-Integrated Chip.
