Semiconductor processes continue to upgrade, with significant growth in manufacturing processes and investment

Advances in semiconductor processes require the development of higher integration density processes, which continue to become more difficult to achieve. Over the past half century, the growth rate of semiconductor device performance has followed the famous Moore's Law. Advanced semiconductor processes have developed from planar structures to 3D structures, transistor areas have been shrinking, and the number of transistors that can be accommodated in integrated circuits has doubled in about 18 months.

Method of handling coated optical equipment

1. Fold the cotton wipe, soak the edge with acetone, and carefully clean the edge of the reflector in the clockwise/counterclockwise direction; 2. Shake the bottle with molybdenum liquid properly; 3. Pull out a new cotton wipe and fold it, and soak its edges with molybdenum liquid, or drip several drops of molybdenum liquid directly on the mirror surface. 4. Starting from the edge of the mirror, gently drag the cotton cloth on the mirror surface, and repeat the above process several times continuously, so that the molybdenum cleaning agent should slowly volatilize. 5. Take out another cotton wipe and dry the molybdenum solution on its surface. Pay attention to wipe should move back and forth or do circular motion. 6. Then the edge of a piece of folded cotton cloth is soaked with acetone, gently dragging on the mirror surface, starting from the edge of the mirror. The above process is repeated until the mirror is clean. 7. In order to extend the life of the mirror, you can use pure air or nitrogen to gently blow the mirror.
