Laser-Induced Forming and Transfer of Shaped Metallic Interconnects
A method of forming and transferring shaped metallic interconnects, comprising providing a donor substrate comprising an array of metallic interconnects, using a laser system to prepare the metallic interconnects, forming shaped metallic interconnects, and transferring the shaped metallic interconnect to an electrical device. An electronic device made from the method of providing a donor ribbon, wherein the donor ribbon comprises an array of metal structures and a release layer on a donor substrate, providing a stencil to the metal structures on the donor substrate, applying a laser pulse through the donor substrate to the metal structures, and directing the metal structures to an electronic device.
SEMICONDUCTOR APPARATUS AND METHOD FOR MANUFACTURING THE SAME, AND POWER CONVERSION APPARATUS
A semiconductor apparatus includes a semiconductor device, a lower wire member, and an upper wire member. The semiconductor device includes a semiconductor device body having a main surface, and a metal layer. The lower wire member includes an end surface and an end surface. In a plan view of the main surface, the end surface and the end surface are located inside a periphery of the semiconductor device. The upper wire member is stacked on the lower wire member. In the plan view of the main surface, a portion of the upper wire member is located outside the periphery of the semiconductor device. The upper wire member is joined to the metal layer with the lower wire member being interposed therebetween.
