Abstract
The present invention provides a semiconductor device wherein a semiconductor chip is fixed on a mount body without a short circuit. A positive electrode (42) is provided above a conductive substrate through an insulating layer (38). The electrode (42) have a concavity (43). A bonding connector consists a first bonding connector (70) on the electrode (42) and a second bonding connector (71) around the first bonding connector (70), the first bonding connector being more fluid than the second bonding connector at a certain temperature. A LASER chip (30) is fixed on the second bonding connector (71).
