Hi! I am Ray from Taipei. I graduated with master’s degree in electrophysics from National Chiao Tung University, and I have bachelor’s degree in physics form National Chung Hsing University. Presently, I am a optical engineer in camera department of Hon Hai Precision Industry Co., Ltd.

Since majoring in physics and electrophysics, I am well-trained in the fields of physic, optics, electronics, semiconductor and thin films analysis. The training also have established me logical thinking afterward helped me to face challenge. 

My master’s thesis is “A study of MoS2 thin films deposited and annealed by femtosecond laser”. I had an in-deep studying of pulse laser deposition, laser annealing, ultrafast pump-probe system and 2D materials. Also, I am familiar with setup of optical experiment and various kinds of measure instruments such as Raman, XRD, SEM and EDS. By this period, I have learned how to design an experiment and improve it.

I am proactive to every opportunity. I joined TSMC to be an intern in first year of my master’s degree. I have learned about department work and corporation with other teams. Additionally, during postgraduate, I used to be a teaching assistant responsible with preparing the course content and providing tutor to students, and this experience has trained me with communicating to different people as well as improving my expression skill. 

My hobby is basketball. I used to be the leader of basketball team of department in college. To be a good leader, I needed to lead the way of my team and I like to get to the better performance with my team. In basketball team, I have learned the responsible attitude and the importance of cooperation. 

Besides, Python is my another hobby. I am familiar with establishing mathematical model with Python to analyze my experimental data. In current job, I also coded the graphical tool and analyzing datum by Python. 

Presently, I am an optical engineer, my main duty is camera module test and product management. In company, I have realized the assembly of products and function test of camera modules such as auto-focus and OIS system. Also, I take responsibility of communicate with client, analyzing datum to failure analysis report and suggesting solution. 

In the eyes of my family and friends, I am an affirmative person who can face things optimistically. Also, I am willing to face challenges and rise myself to be a better person. I believed my experience and enthusiasm can help me to excel in my role in company. Thank you!
