Abstract:
1. A method for providing adhesion between a plurality of layers in a semiconductor device, comprising: forming a first layer comprising organo-silicate glass, the first layer overlying a base layer having a conductive portion; forming a trench in the first layer, the trench at least partly overlying the conductive portion; lining the trench with a second layer comprising titanium silicon nitride approximately 10 Angstroms thick, the second layer in direct contact with and overlying the first layer; after lining the trench with the second layer, directly exposing the second layer to plasma at a first power level between approximately 500 to 1500 watts, the first power level sufficient for plasma to reach the first layer through the second layer; and after directly exposing the second layer, forming a third layer in the trench, the third layer in direct contact with and overlying the second layer.
