Abstract

PURPOSE:To facilitate the detection of the junction position by attaching an electrolyte containing a cupric sulfate to the junction to yield a copper plating on a P-type layer along with a negative voltage applied to the P-type layer exposed of a multi- element semiconductor substrate as cleaved and a positive voltage to an N-type layer. CONSTITUTION:An insulating resin 3 is embedded into one end A of a pair of metal pieces 1 and 2 made of a stainless steel or the like to make such a tweezers construction with the metal pieces 1 and 2 which pinch a semiconductor substrate 4 of PbS1-xSex cleaved at the other end B thereof. At this point, a cleaved surface C is so projected to cover an N-type layer 4B sufficiently with the tip of the metal piece 2 while the metal piece 1 is shortened enough to leave a part of the layer 4A expose. In this arranement, while DC power source is applied to the metal piece 4B through the metal piece 2 on the positive side thereof and to the layer 4A through the metal piece 1 on the negative side thereof, an electrolyte containing cupric sulfate is attached to a cleaved surface C with an applicator. Thus, a copper plating is made on the layer 4A alone thereby allowing the detecting of the position of a P-N junction 6.
