IPC: H01L21/31
Filed: 1993-10-20
Abstract: PURPOSE:To provide an interlayer insulation film excellent in step coverage and planarity through which a contact hole having low contact resistance can be made. CONSTITUTION:The level difference between metallizations 14a, 14b caused by a field oxide 12 is eliminated by an interlayer insulation film of layer structure comprising interlayer insulation films 15-17. The interiayer insulation films 15, 17 of uniform thickness are formed by plasma CVD using TEOS. The, interlayer insulation film 16 is formed by plasma CVD using trifluoromethyl ethoxysilane and excellent in step coverage and planarity. Since the etching rate for the interlayer insulation film 16 is higher than that for the interlayer insulation films 15, 17, and thereby the etching time is substantially equalized for the contact holes 18a, 18b regardless of the depth. Consequently, the time interval when the wiring layer 14a on the bottom of the hole 18a is exposed to the plasma of etching gas is shortened and the amount of reaction products is reduced thus lowering the contact resistance.
