Abstract:
Electrical properties of a semiconductor device are reproducibly and stably measured in a testing step of the semiconductor device. A probe pin includes a first plunger, a second plunger, a cleaning shaft, a first coil spring, and a second coil spring. The cleaning shaft accommodated in the inside of the first plunger is allowed to enter and exit through a tip of a contact of the first plunger by the second coil spring, thereby solder shavings attached to the tip of the contact are removed. The first plunger is electrically coupled to the second plunger by the first coil spring wound on an outer side face of the first plunger and on an outer side face of the second plunger.

Claim (Index 16):
A method of manufacturing a semiconductor device, comprising:\n (a) providing a semiconductor wafer having a main surface divided into a plurality of chip regions, each of the chip regions having a semiconductor integrated circuit; and (b) bringing a probe pin into contact with each of a plurality of electrode pads provided on the respective chip regions to measure electrical properties of the respective semiconductor integrated circuit, the probe pin including: (i) a hollow-structured first plunger that configures an upper part of the probe pin and has a contact that comes into contact with the electrode pad; (ii) a hollow-structured second plunger that configures a lower part of the probe pin separately from the first plunger, and has a bottom at an end on a side opposite to the first plunger; (iii) a cleaning shaft that is accommodated inside the first plunger, and partially projects from a tip of the contact; (iv) a first coil spring that is wound on an outer side face of the first plunger and on an outer side face of the second plunger, and electrically couples the first plunger to the second plunger; and (v) a second coil spring that is accommodated inside the first plunger and inside the second plunger while being held between the cleaning shaft and the bottom of the second plunger, wherein when part of the cleaning shaft enters and exits through the tip of the contact, a foreign substance attached to the tip of the contact is removed.
