ABSTRACT:
An assembly substrate includes a substrate (11, 31, 41), a composite layer (12, 32, 42) overlying the substrate (11, 31, 41), and an electrically conductive layer (13, 33, 43) overlying the composite layer (12, 32, 42). The composite layer (12, 32, 42) includes a first material having an as-deposited tetragonal crystal structure and a second material. The second material in the composite layer (12, 32, 42) reduces the susceptibility of the composite layer (12, 32, 42) to fracture under stress.
