Abstract
An injector for forming films respectively on a stack of wafers is provided. The injector includes a plurality of hole structures. Every adjacent two of the wafers have therebetween a wafer spacing, and each of the wafers has a working surface. The hole structures respectively correspond to the respective wafer spacings. The working surface and a respective hole structure have therebetween a parallel distance. The parallel distance is larger than a half of the wafer spacing. A wafer processing apparatus and a method for forming films respectively on a stack of wafers are also provided.
