Patent ID: 7749883

Claim:
A method for providing metallization upon a semiconductor substrate, the method comprising: providing a semiconductor substrate having a surface suitable for printing; placing a stencil having a contact side, a fill side, and at least one aperture extending from the contact side to the fill side over the semiconductor substrate with the contact side of the stencil in contact with the semiconductor substrate, the contact side of the stencil being substantially flat and forming a sharp edge with a wall of the at least one aperture, a cross-section of the at least one aperture at the contact side having a predetermined width, and the at least one aperture being tapered such that an area of a cross-section of the at least one aperture at the fill side is larger than an area of the cross-section of the at least one aperture at the contact side; and printing conductive ink through the at least one aperture and onto the semiconductor substrate, the conductive ink being printed in direct contact with the semiconductor substrate.
