Core Advantages of Semiconductor Lithography Machine Granite Bases I. Ultimate Thermal Stability, Eliminating Nan-Scale Thermal Drift (Core Requirement for Lithography)The dedicated semiconductor granite has an extremely low coefficient of thermal expansion, only 1/4 of steel and 1/ of aluminum alloy. Under minute temperature fluctuations, its deformation is minimal, preventing lithography overlay offset and pattern misalignment,…
