Considered the most expensive machine in the world, lithography equipment is full of new discoveries and excitement every day. I get pleasure in gaining experience not only in optics, but also in statistics, chemistry, metrology, and many other areas!

Not only me, but my fab as a whole has achieved very high yields on new DRAM products in a very short period of time. I was involved in the product launch team, mainly in the photolithography department. I actually improved the yield by a few tenths of a percent through better overlay accuracy and defect improvement.
