Title: Mesa type diode and its manufacturing method
Inventor: ECHIGOYA TOSHIO
IPC: H01L29/861
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To improve reliability of solder connecting of a connecting terminal to a small-diameter circular portion in a mesa type diode. SOLUTION: The connecting terminal 2 is solder connected to the small- diameter circular portion 12 of a mesa type diode chip 1. The terminal 2 has an oblique surface 22 in an opposite direction to a slope of a bevel part 11 of the chip 1 and a hole 23 at a center. A solder 4 is wetted from the circular portion 12 of the chip 1 along both a conical inner peripheral surface 22 and an outer peripheral surface 28 of the terminal 2. Since the solder 4 is drawn in an upward direction of the hole 23 and wetted along the surfaces of the terminal 2 in a molten state, possibility of generating small bubbles therein is suppressed to low, and connecting reliability can be improved by this property.
