Korean maker of photoresist-strip (ashing) and thermal-processing equipment for semiconductor wafer fabs.
Korean maker of photoresist-strip (ashing) and thermal-processing equipment for semiconductor wafer fabs.
Sells tools to chipmakers in lumpy orders tied to when they build or upgrade fabrication lines, then earns repeat revenue from parts and servicing of the installed machines.
