Two-Stage Exposure Machine - Manual CCD Alignment System

Fully automatic single-sided exposure machine

Auto Exposurer 3", 4", 5", 6" 300-CC This equipment is a photomask alignment exposure machine used in semiconductor lithography process.

Function: Use UV parallel light source to make 1:1 copy of the pattern of the photomask to the photoresist film on the wafer surface.

Using variable magnification lens to facilitate alignment operation, standard total magnification 50X-300X

■ Equipment Specifications:

• Exposure light source , mask line width reproduction capability , I-line positive photoresist 1um thickness, hard contact, 1um~2um,proximity 3um~5um.

■ Align the imaging system:

• Automatic alignment ability, the align key with clear geometric shape can be identified within 5um.

■ Production   can:

• For the alignment process , the exposure time is 3 seconds, and the mechanical capacity is 250 to 300 pieces per hour (without considering the material variability).
• No alignment, only exposure process, exposure time of 3 seconds, mechanical capacity of 280~360 pieces per hour (without considering material variability and unloading).
