Claim:
1. A slip layer substrate, comprising: a base material; a first metallization layer formed on the base material; a first diffusion barrier layer formed on the first metallization layer that the first metallization layer is sandwiched between the base material and the first diffusion barrier layer; a slip layer formed on the first diffusion barrier layer that the first diffusion barrier layer is sandwiched between the slip layer and the first metallization layer, wherein the slip layer is made of malleable and ductile material and has a low mechanical strength; a second diffusion barrier layer formed on the slip layer that the slip layer is sandwiched between the second diffusion barrier layer and the first diffusion barrier layer, wherein the first diffusion barrier layer and the second diffusion barrier layer are made of cobalt; and a second metallization layer formed on the second diffusion barrier layer that the second diffusion barrier layer is sandwiched between the second metallization layer and the slip layer.
