Having 2.5 years of experience in the semiconductor industry, I have learned to be a good team player and analyzed issues comprehensively and thoroughly through discussions. And the most important thing is I like solving problems through teamwork. Besides, the reason that motivated me to apply for the job position was that I would like to reach further and deeper in the semiconductor industry not only from the aspect of manufacturing but also from that of designing and testing.
