ELECTROFORMED STENCILS FOR SOLAR CELL FRONT SIDE METALLIZATION

摘要

A method for providing metallization upon a semiconductor substrate utilizing a stencil having at least one aperture extending from the contact side to the fill side, the contact side of the stencil being substantially flat and forming a sharp edge with a wall of the at least one aperture, 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. A method of forming a stencil for depositing metallization lines on a semiconductor substrate is also disclosed.
