300 Series Stepper —— LED/ MEMS/ Power Devices


SSB300

SSB320

SSB380

SSB300/30 stepper is designed for substrates of 2-6 inches applied in PSS and electrode lithography process. It has high resolution and CD uniformity. SSB320/10 is specially designed for LED Chip lithography process. Ultra-large exposure field is adopted. With optimized reticle design, the exposure field is smaller, so that the loss of repeated chips is reduced and the throughput is improved greatly.
   Product Features

● Resolution up to 0.8μm

● Fast online mapping tech

● Precise stitching

● Self-adaption switching between different substrates

● High throughput

● Precise overlay

● Perfectly match with aligner
