Patent ID: 8507369

Claim:
A method for producing silicon nanowire devices including the following steps: S 101 : Growing silicon nanowire (SiNW) on a substrate; S 102 : Depositing an amorphous carbon layer to cover the SiNW, followed by depositing a dielectric anti-reflectivity coating on the amorphous carbon layer; S 103 : Removing part of the dielectric anti-reflectivity coating and the amorphous carbon layer above the SiNW through dry etching to expose the SINW device area; S 104 : Depositing an oxide film on the surface of the above structure formed by S 103 ; S 105 : Forming a metal pad connected with the SiNW in the SiNW device area; S 106 : Depositing a passivation layer on the surface of the above structure formed by S 105 ; S 107 : Applying photolithography and etching technology to form contact holes on the metal pad and to remove the passivation layer, the oxide film and the dielectric anti-reflectivity coating above the SiNW outside the SiNW device area, and stopping on the amorphous carbon layer; S 108 : Removing the amorphous carbon layer above the SiNW outside the SiNW device area through ashing process to expose the SiNW.
