Title:
METHOD OF LASER IMPRINTING
Document Type and Number:
Japanese Patent JPH0247856
Kind Code:
A
Abstract:

PURPOSE: To prevent the lead of a semiconductor device from bending and increase the processing speed by inclining a stick-shaped magazine, in which a plurality of semiconductor devices are contained, in the direction of the width thereof, arranging the semiconductor devices on one surface of the magazine for positioning, and performing imprinting in the magazine.

CONSTITUTION: Supplying a high pressure air to a cylinder 6 raises a cylinder rod 12 to move a stick-shaped magazine 2 arcuately upward around a fulcrum 10 as the center of rotation until it comes into contact with stoppers 4. In this time, semiconductor devices 1 in the stick-shaped magazine 2 are arranged in a row on one surface 9 of the stick-shaped magazine 2 for positioning. A laser optical system 5 moves, a laser beam is applied through a lens 13 to imprint the semiconductor devices 1. This structure improves the imprint processing ability and prevents the leads of the semiconductor devices from bending to improve the quality.
