Abstract:
A semiconductor device, comprising:a semiconductor material having a first region doped to be a semiconductive material of a first type, and a second region doped to be a semiconductive material of a second type opposite to the first type; a first alloy making ohmic contact to the first region, the first alloy comprising at least a portion of a first dopant and eutectic proportions of silver and the semiconductor material first region which have been heated above the eutectic point of the first alloy and then cooled below the eutectic point of the first alloy to form a first solid ohmic contact region; and a second alloy making ohmic contact to the second region, the second alloy comprising at least a portion of a second dopant and eutectic proportions of silver and the semiconductor material second region which have been heated above the eutectic point of the second alloy and then cooled below the eutectic point of the second alloy to form a second solid ohmic contact region.
