Patent ID: 7820462

Claim:
A screen-printing method of encapsulating an optoelectronic chip on a substrate, the method comprising: providing a substrate having an upper surface; securing an optoelectronic chip on said upper surface; on said upper surface, providing borders with a height that surround at least a portion of said optoelectronic chip, said height being determined in accordance with a desired thickness for an optical window; applying a light transmissible coating over at least a portion of the optoelectronic chip; squeegeing said coating to create said optical window having said desired thickness, said squeegeing comprising abutting a flat edge tool against top ends of the borders and dragging the flat edge tool on top of the light transmissible coating while maintaining contact with the borders; and allowing said coating to harden, to thereby provide an encapsulated optoelectronic chip on said substrate.
