Abstract:
The described embodiments relate generally to aluminum films and pretreatments for improving the adhesion of aluminum films on substrate surfaces. Methods involve providing three-dimensional adhesion surfaces on the substrate that promote adhesion to a subsequently deposited aluminum film. The methods can avoid the use of strike materials, such as nickel and copper, used in conventional adhesion-promoting treatments. According to some embodiments, methods involve providing an aluminum oxide adhesion layer on the substrate prior to depositing aluminum. According to some embodiments, methods involve providing a zincating layer on the substrate prior to depositing aluminum. According some embodiments, methods involve roughening the surface of the substrate prior to depositing aluminum. Some embodiments involve a combination of two or more substrate pretreatments. Described methods can be used to provide more flexibility in subsequent anodizing processes. In some embodiments, methods involve anodizing the aluminum film and a portion of the substrate.

Claim (Index 15):
A method for forming an aluminum layer on a substrate, the method comprising:\n forming an aluminum oxide adhesion layer on the substrate, the aluminum oxide adhesion layer having a plurality of pores defined by a plurality of corresponding pore walls; during the forming, controlling an average pore size of the aluminum oxide adhesion layer by simultaneously allowing growth of the pore walls and dissolving the pore walls and dissolving that the average pore size is sufficiently large to allow aluminum material to form therein during a subsequent aluminum layer depositing process; and depositing the aluminum layer on the aluminum oxide adhesion layer, wherein during the depositing, anchoring portions of the aluminum layer form within at least a portion of corresponding pores, wherein the anchor portions engage with the pore walls resisting a shearing force applied to the aluminum layer and securing the aluminum layer to the aluminum oxide layer.
