    Abstract: A method for forming a fluid feed via in a semiconductor substrate chip for a micro-fluid ejection head. The method includes applying a photoresist planarization and protection layer to a first surface of the chip. The photoresist planarization and protection layer is patterned and developed to define at least one fluid feed via location. A strippable layer is applied to the photoresist planarization and protection layer on the chip. The strippable layer is patterned and developed with a photomask to define the at least one fluid feed via location in the strippable layer. The chip is then dry etched to form at least one fluid feed via in the defined feed via location. Before or after etching the chip, deprotection of the strippable layer is induced so that the strippable layer can be substantially removed with a solvent without substantially affecting the photoresist planarization and protection layer.

    Abstract: A semiconductor device is disclosed which can be miniaturized and in which structures on a semiconductor substrate therein are difficult to delaminate, as well as a method of producing the same. The semiconductor device includes a semiconductor substrate main unit, and a thin portion that is thinner than the main unit and formed such that a recessed portion is formed in the semiconductor substrate and has at least one through hole formed therein. The thin portion is formed such that the etching rate of the thin portion is slower than the etching rate of the main unit. The thin portion provides a bridging structure between both sides of the recessed portion, and can mechanically and structurally strengthen the semiconductor device with respect to forces applied from the side surfaces of the main unit of the semiconductor substrate. Thus, structures such as wires, films, and semiconductor elements formed on the main unit and/or the thin portion of the semiconductor substrate or via the through holes will be difficult to detach from the semiconductor device.

    Abstract: A method for the formation of a multi-nozzle ink jet is herein disclosed. In this method a single crystal silicon plate is masked and impurities are diffused upon its surface, creating regions of echant resistance. A second single crystal silicon plate is then grown onto the first, and is masked and etched. Due to the unisotropic etching properties of single crystal silicon plates, a groove is formed in the second plate, and a plurality of nozzles is formed in the first plate. This process yields a multi-nozzle ink jet of greater overall strength and utility, while eliminating the waste due to etching run common in the manufacture of conventional ink jets.

    Abstract: The present disclosure provides a MEMS device having a movable portion. The MEMS device includes: a substrate; a recess, disposed in the substrate; the movable portion, hollowly supported in the recess; and a bump stop, hollowly supported in the recess and configured to restrict a movement of the movable portion by contacting the movable portion. The bump stop includes: a protruding portion, configured to contact the movable portion; and a shock absorbing portion, disposed between the protruding portion and the substrate and configured to absorb at least a part of an impact force applied to the protruding portion by elastic deformation.
