となり、凹部28以外においてウェハ40が引っ掛かる場合のLの値(L2とする)は、
(2・Rw−Rp)2=Hp2+L22 ……………(式4)
となる。
Li<L1 ………………………(式5)
Lo>L2 ………………………(式6)
となる。
w>d・sinθ ……………(式7)
と表すことができ、上記θは、
tanθ=Hp/L1 ………(式8)
の関係式から求めることができる。
(2・Rwmin−Rp−d)2=Hp2+L12 ………(式9)
(2・Rwmax−Rp)2=Hp2+L22 ……………(式10)
と書き改めることができる。上記式9により求められるL1をL1min、式10により求められるL2をL2maxとすると、式5及び式6は、
Li<L1min ………………………(式11)
Lo>L2max ………………………(式12)
と書き改めることができる。
Li<√((2・Rwmin−Rp−d)2−Hp2) …………(式13)
Lo>√((2・Rwmax−Rp)2−Hp2) ………………(式14)
を満たすように設定すべきことが分かる。また、凹部28の開口長(Lo−Li)は、ウェハ40の裏面へのガスの回り込みを少なくする観点から、なるべく小さいほうが好ましい。具体的には、ウェハ40のOF長をLfとした場合に、以下の関係式を満たすようにすることが好ましい。
Lo−Li<Lf/4 …………………(式15)
h≧Rw/500 ………………………(式16)
10°≦α≦80° ……………………(式17)
これにより、ウェハ40の側面に加工ムラがあった場合でも、ウェハ40の段差部30における引っ掛かりを抑制することができる。また、上記αの範囲は、更に下記の関係式を満たすことがより好ましい。
30°≦α≦60° ……………………(式18)
