| titleOfInvention |
Hydrogen plasma photoresist strip and polymeric residue cleanup process for low dielectric constant materials |
| abstract |
A method ( 100 ) of fabricating an electronic device ( 200 ) formed on a semiconductor wafer. The method forms a layer ( 215 ) of a first material in a fixed position relative to the wafer. The first material has a dielectric constant less than 3.6. The method also forms a photoresist layer in ( 216 ) a fixed position relative to the layer of the first material. The method also forms at least one void ( 220 ) through the layer of the first material in response to the photoresist layer. Further, the method subjects ( 106 ) the semiconductor wafer to a plasma which incorporates a gas which includes hydrogen so as to remove the photoresist layer. |
