Silicon Ingot Processing in Semiconductor Industry
Key Takeaways In semiconductor wafer preparation, single-crystal silicon ingots are processed into bare wafers with high surface accuracy for lithography. The ingot processing flow includes cropping, 研磨, 切片, 倒角, lapping and polishing, with slicing quality setting downstream workload. 在单晶硅晶圆制备阶段, 硅锭需要加工成具有高表面精度和表面质量的原始硅片或裸硅片，为IC工艺前半段的光刻等工艺的平坦化做准备.
