JUMPER CHIP FOR SEMICONDUCTOR DEVICES

摘要

In the manufacture of semiconductor device packages, a jumper chip, comprising a substrate (11) and a gold alloy (13) attached thereto, with improved bonding characteristics is provided. By applying a coating (14, 15) of gold on both sides of the gold alloy (13) prior to attaching the gold alloy to the substrate (11), the bonding of the gold alloy (13) to the substrate (11) and to the gold coating of the cavity in a device package is improved. Scrubbing of the jumper chip on the gold coating of the cavity is obviated. The additional gold layers applied to the gold alloy are distinct and visible on a photograph of a cross-section of the jumper chip.
