Patent ID: 7923706

Claim:
An ultraviolet radiation curing system for treating a substrate having a longitudinal axis, comprising: a processing chamber having an inlet port capable of receiving the substrate for positioning in said processing chamber and an outlet port capable of permitting the substrate to exit said processing chamber; a longitudinally-extending plasma lamp mounted within said processing chamber and capable of emitting ultraviolet radiation; a microwave generator coupled to said processing chamber for exciting said plasma lamp to emit ultraviolet radiation, a first portion of said ultraviolet radiation directly irradiating the substrate without reflection; a longitudinally-extending ultraviolet-transmissive conduit positioned within said processing chamber and enclosing the substrate when the substrate is positioned within said processing chamber; a longitudinally-extending first reflector mounted within said processing chamber, said first reflector having an elliptical first reflective surface defined by a first “a” distance, a first “b” distance, a first focal line substantially collinear with said plasma lamp, and a second focal line substantially collinear with the longitudinal axis of the substrate, said first reflective surface oriented relative to said plasma lamp for reflecting a second portion of said ultraviolet radiation to irradiate the substrate; and a longitudinally-extending second reflector mounted within said processing chamber, said second reflector having an elliptical second reflective surface defined by a second “a” distance larger than said first “a” distance, a second “b” distance larger than said first “b” distance, a third focal line substantially collinear with the longitudinal axis of the substrate, and a fourth focal line substantially collinear with said plasma lamp, said second reflective surface oriented relative to said plasma lamp for reflecting a third portion of said ultraviolet radiation to irradiate the substrate.
