It sensitizes semiconductor wafers or subtrates with a mask and exposes them to ultraviolet radiation to transfer the pattern of the mask to substrate for further processing on the way to producing a semiconductor or other microelectronic device.
Ultra Violet Light - The Quintel uses broadband ultraviolet light (UV) to expose photoresist.
Light Source - It uses 350 W Hg short ARC lamp with broadband UV light.
Wafer Diameter Length - 4 in. diameter
operations - 1. Pressure contact mode
2. Contact exposure mode
