Patent ID: 8592324

Claim:
A method for forming a laminated structure including an amorphous carbon film, which is a film consisting of amorphous carbon, on an underlying layer consisting of SiO 2 on each of target objects, the method comprising: forming an initial layer of Si—C bonds, which is to improve adhesiveness between the underlying layer and the amorphous carbon film, on a surface of the underlying layer inside a process chamber with the target objects placed therein at intervals in a vertical direction, by supplying an organic silicon gas as a pretreatment gas into the process chamber while heating the target objects, the organic silicon gas being a sole source gas for Si and C of the initial layer of Si—C bonds, and the organic silicon gas being an aminated compound gas containing silicon, which is selected from the group consisting of butylamino silane, bistertialbutylamino silane, dimethylamino silane, bisdimethylamino silane, tridimethylamino silane, diethylamino silane, bisdiethylamino silane, dipropylamino silane, and diisopropylamino silane; and successively forming the amorphous carbon film by thermal film formation on the surface of the underlying layer through the initial layer of Si—C bonds inside the process chamber with the target objects kept placed therein, by supplying a hydrocarbon compound gas as a film formation gas into the process chamber while heating the target objects, the hydrocarbon compound gas being selected from the group consisting of CH 4 , C 2 H 2 , C 2 H 4 , C 2 H 6 , C 4 H 6 to thereby form the amorphous carbon film on the underlying layer through the initial layer of Si—C bonds.
