  • Method for producing a tin-zinc alloy film
    Patent number: 6709719
    Abstract: A tin layer and a zinc layer are stacked sequentially on a given substrate to form a multilayered film composed of the tin layer and the zinc layer. Then, a laser beam is irradiated onto the multilayered film to produce a tin-zinc alloy film through the inter-diffusion between the tin elements of the tin layer and the zinc elements of the zinc layer.
    Type: Grant
