摘要: A method of etching a semiconductor substrate. The method includes the steps of applying a photoresist etch mask layer to a device surface of the substrate. A select first area of the photoresist etch mask is masked, imaged and developed. A select second area of the photoresist etch mask layer is irradiated to assist in post etch stripping of the etch mask layer from the select second area. The substrate is etched to form fluid supply slots through a thickness of the substrate. At least the select second area of the etch mask layer is removed from the substrate, whereby mask layer residue formed from the select second area of the etch mask layer is significantly reduced.

摘要: A method for improving fluidic flow for a microfluidic device having a through hole or slot therein. The method includes the steps of forming one or more openings through at least part of a thickness of a substrate from a first surface to an opposite second surface using a reactive ion etching process whereby an etch stop layer is applied to side wall surfaces in the one or more openings during alternating etching and passivating steps as the openings are etched through at least a portion of the substrate. Substantially all of the etch stop layer coating is removed from the side wall surfaces by treating the side wall surfaces using a method selected from chemical treatment and mechanical treatment, whereby a surface energy of the treated side wall surfaces is increased relative to a surface energy of the side wall surfaces containing the etch stop layer coating.

摘要: A process for etching semiconductor substrates using a deep reactive ion etching process to produce through holes or slots (referred to collectively as “slots”) in the substrates. The process includes applying a first layer to a first surface of substrate to provide an etch mask material layer on the first surface of the substrate. A second layer is applied to a second surface of the substrate to provide an etch stop material layer on the second surface of the substrate. The first layer and the second layer have similar solubilities in one or more organic solvents. The substrate is etched from the first surface of the wafers to provide a slot in the substrate. After etching the substrate, the etch mask material layer and the etch stop material layer are removed by contacting the first surface and the second surface of the substrate with a single organic solvent.

摘要: A method of substantially simultaneously forming at least two fluid supply slots through a thickness of semiconductor substrate from a first surface to a second surface thereof. The method includes the steps of applying a photoresist layer to the first surface of the semiconductor substrate. The photoresist layer is patterned and developed using a gray scale mask for a first fluid supply slot. The semiconductor substrate is then reactive ion etched, to form the at least two fluid supply slots through the thickness of the substrate. The first fluid supply slot is substantially wider than the second fluid supply slot, and the first and second fluid supply slots are etched through the substrate at substantially the same rate.
