Imec and EVG have demonstrated 1.8µm pitch overlay accuracy for wafer-to-wafer bonding. Wafer-to-wafer bonding is a promising technique for enabling high-density integration of future ICs through 3D ...
Synopsys, Inc. (NASDAQ: SNPS) today announced a pre-wafer simulation solution to help semiconductor manufacturers reduce process node development time. The new solution provides a comprehensive ...
The testing of the semiconductor dies produced by a wafer fabrication plant involves a long series of operations requiring meticulous care. The time spent performing these tests markedly affects both ...
One of the contributors to layer-to-layer overlay in today’s chip manufacturing process is wafer distortion due to thin film deposition. Mismatch in the film specific material parameters (e.g., ...
Overlay metrology tools improve accuracy while delivering acceptable throughput, addressing competing requirements in increasingly complex devices. In a race that never ends, on-product overlay ...
