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

Modes of operations - 1. Pressure contact mode                                  
                                2. Contact exposure mode
