Abstract

PURPOSE:To enhance the imprinting performance and durability of a mark by a method wherein, before a semiconductor device is marked, the surface to be marked is irradiated with the focused light so that release agents and oily and fatty substance are removed completely. CONSTITUTION:A laser L2 which has passed through a flexible slit 4 is focused by using a lens 5 and then irradiates a marking plane 8a. A diameter H of a spot 13 is adjusted in such a way that a marking region 14 can be irradiated. Then, a semiconductor device 8 which has reached a marking part 9 is stopped at a marking position; after that, an upward and downward movable axis 10 is lowered from the upper part and a marking stamp 12 is pressed onto the marking plane; a mark is printed. By this setup, the imprinting performance and durability of the mark can be enhanced.

Next, the operation of this embodiment will be explained. Laser oscillator 1
The beam expander 3 expands the light diameter of the laser L generated from the slit 4, and the expanded laser L is sent into the flexible slit 4 in order to control the size and shape of the light irradiated to the semiconductor device 8. . The laser L that has passed through this flexible slit 4 is focused by a lens 5,
The mark surface 8a is irradiated. Spot 13 at this time (
The diameter H of the laser beam at the mark surface can be defined by the aperture diameter of the flexible slit 4 and the distance between the lens 5 and the mark surface. The diameter (I) of this spot 13 is made larger than the size of the characters, and by simply moving the mark surface once, it is possible to irradiate the minimum marking area 14 that requires removal of the release agent and oil. The semiconductor device 8 is moved on the transport chute 7 by a transport claw (not shown) and undergoes mark preprocessing using the laser L. Next, the semiconductor device 8 that has reached the marking portion 9VC stops at the marking position, and then the vertical movement shaft 10 descends from above to press the mark mark 12 onto the mark surface to form a mark.
