Title: Laser annealer
Inventor: SAWAI YOSHIKI
IPC: H01L21/20
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To enable improvement in quality by reducing fluctuation of annealing, and prevent generation of energy loss of laser beams. SOLUTION: A laser beam L is selectively transferred to a first irradiation position P1, where a substrate 15 is irradiated with the laser beam. During this process, a moving table 17 on which the substrate 15 irradiated with the laser beam is set is moved from a second irradiation position P2, and a moving table on which an unprocessed substrate is set is moved to the second irradiation position P2. On completion of irradiation at the first irradiation position P1, the laser beam L is transferred to the second irradiation position P2 where the substrate is irradiated with the laser beam. During this process, the moving table 17 on which the substrate irradiated with the laser beam is set is moved from P1, and the moving table on which an unprocessed substrate is set is moved to P1.  Let n be the minimum integer not smaller than (S/A+1), where S denotes the time for transporting the unprocessed substrate to the irradiation position and transporting the processed substrate from the irradiation position while A denotes the irradiation time, the laser oscillation is stabilized, thus stabilizing annealing process and improving the quality.

Abstract: PURPOSE:To prevent performance degradation even with a gold plating layer by forming and Ni-Fe alloy layer on the surface of a chip mount part as a base material for a gold plating layer. CONSTITUTION:A silicon semiconductor chip is, through an Au-Si eutectic reaction, mounted on a chip amount part, and the chip mount part has a gold plating layer on its surface, a semiconductor package thus configured.
