Abstract:
A method of adhering a silicate layer to dielectric layer, comprising the steps of:providing a structure having an overlying layer formed thereover; forming an adhesion promoter layer upon the layer; the adhesion promoter layer including adhesion promotion molecules; treating the layer and the adhesion promoter layer to a low-temperature treatment to bind at least some of the adhesion promotion molecules to the layer through a first Siâ€”O group; forming a silicate layer upon the low-temperature treated adhesion promoter layer; and treating the silicate layer and the low-temperature treated adhesion promoter layer to a high-temperature treatment to bind at least some of the adhesion promotion molecules to the silicate layer through a second Siâ€”O group or an Râ€”O group; whereby the silicate layer is adhered to the dielectric layer.
