Abstract: A gas supply assembly for a substrate processing apparatus includes a gas introduction part, a gas distribution plate connected to the gas introduction part, the gas distribution plate including a plurality of through holes, and a shower head disposed under the gas distribution plate, the shower head including a plurality of distribution holes in fluid communication with the plurality of through holes. One through hole is in fluid communication with at least two distribution holes, and each of the plurality of distribution holes has a first diameter and a second diameter differing from each other in the shower head.

Abstract: A gas injection module includes a showerhead having first injection holes on a first region of the showerhead and second injection holes on a second region of the showerhead, the second region being outside the first region, a first distribution plate on the showerhead and having first and second upper passages respectively connected to the first and second injection holes, and a flow rate controller on the first and second upper passages of the first distribution plate. The flow rate controller reduces a difference in pressure within the first and second upper passages so that the gas may have similar flow rates within the first and second injection holes.
