What will AGI do for Thermal Yield Scrap Loss?
Semiconductor fabs and advanced materials manufacturers routinely discard perfectly processed batches due to micro-fractures, warpage, and dopant diffusion caused by uneven cooling. Thermal yield scrap loss occurs when minute spatial temperature variations across a substrate exceed the material tolerance limits during high-heat processes like annealing or curing. Process engineers lack visibility into localized thermal dynamics, forcing them to rely on post-process metrology to discover that an entire wafer or batch is unusable.
