UV Lithography Refers To A Series Of Process Steps Such As Uniform Coating, Exposure, And Development To Remove Specific Parts Of The Wafer Surface And Leave A Thin Film With Micro Patterned Structures. Through The Photolithography Process Steps, The Final Feature Patterned Parts Are Retained On The Wafer. Lithography Technology Is The Center Of The Semiconductor Manufacturing Process, And The Wafer Needs To Undergo Multiple Photolithography Processes During The Manufacturing Process. The Quality Of The Photolithography Process Largely Determines The Graphic Resolution, Yield, And Quality Of Semiconductor Devices. Therefore, Photolithography Is Considered The Most Critical Step In The Semiconductor Manufacturing Industry.
