    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 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 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.

    摘要: An ink refill device includes a body having a chamber with ink therein. The chamber has one wall formed of a frangible material. The body has a needle communicating the chamber with a reservoir, which has a foam of a controlled porosity therein, in a print cartridge when the needle is inserted in a vent of the reservoir to fill the reservoir. Breaking of the frangible wall of the chamber with the needle extending downwardly enables ink to flow from the chamber at a controlled flow rate to the reservoir in the cartridge. In the preferred embodiment, the needle has one or more notched openings adjacent its distal end to increase its surface area through which ink flows to increase flow of ink to the reservoir.
