1. 切边/切槽:我们的wafer都有个Notch (6寸是平边/flat),这个是在ingot做好的时候就要切好的,切成片就没法做了。这个notch或平边不是随便切的哦,它必须沿着<110>向切,所以Wafer规格上规定Notch orientation为110+/-1deg。还有notch的深度以及平边大小都是有SEMI M1规定的,6寸用的平边一般有两种47.5mm和5...

一、Wafer边缘的处理方式 Wafer边缘的处理方式与其尺寸有关。在200mm以下的硅锭上,会切割一个平角,称为Flat(平槽)。而在200mm(含)以上的硅锭上,为了减少浪费,只裁剪一个V形小口,称为Notch(V槽)。这些切割步骤的存在意义在于帮助后续工序确定Wafer的摆放位置,为了定位,也...
