PURPOSE:To make possible a stable stamping to be carried out by arranging the laser stamping heads which stamp the obverse and reverse of a semiconductor apparatus by a laser facing to each other. CONSTITUTION:The laser stamping heads 4 and 5 which stamp the obverse 6a and reverse 6b of a semiconductor 6 by a laser are arranged on the both sides of a conveying passage of a semiconductor apparatus 6 formed in a stamping station 2. The semiconductor apparatus is sent out from supply station 1 and transferred to the stamping station 2. A simultaneous stamping is carried out by the sealing head 4, 5 on the obverse and reverse of the semiconductor apparatus 6 transferred to the sealing station 2. thereby, a printing having a stable quality can be carried out without an ink dripping or the like. |
