Abstract:
1. A semiconductor diode comprising: a semiconductor die including a substrate, a first semiconductor film formed on said substrate, a second semiconductor film formed on said first semiconductor film, a first metal contact formed on said first semiconductor film, and a second metal contact formed on said second semiconductor film, one of said first and second semiconductor films being made of an n-type semiconductor material, the other one of said first and second semiconductor films being made of a p-type semiconductor material, said semiconductor die having two opposing first side edges a and b and two opposing second side edges c and d which cooperate with said first side edges a and b to define two diagonally opposite first corners a and b and two diagonally opposite second corners c and d, said first semiconductor film having an exposed area that is exposed from said second semiconductor film adjacent to first side edge a and that extends between said first corner a and said second corner c, said first metal contact having a first strip portion that is formed on said exposed area, and a first bonding portion that extends from and that has a width greater than that of said first strip portion and a length less than that of said first strip portion, said second metal contact having a second strip portion that is disposed adjacent to said first side edge b and that extends between said first corner b and said second corner d, and a second bonding portion that extends from and that has a width greater than that of said second strip portion and a length less than that of said second strip portion, said first bonding portion being formed on said one of said first corners a and b, said first strip portion extending from said first bonding portion to said one of said second corners c and d, said second bonding portion being formed on the other side of said first corners a and b, said second strip portion extending from said second bonding portion to the other one of said second corners c and d.
