  • Patent number: 7692234
    Abstract: A semiconductor device, which ensures device reliability especially in fine regions and enables great capacitance and high-speed operations, has memory cells including, in a first region of a main surface of a semiconductor substrate, a gate insulating film, a floating gate electrode, an interlayer insulating film, a control gate electrode, and source and drain regions of the second conduction type arranged in a matrix, with a shallow isolation structure for isolating the memory cells. When using a shallow structure buried with an insulating film for element isolation, the isolation withstand voltage in fine regions can be prevented from lowering and the variation in threshold level of selective transistors can be reduced. When the memory cells in a memory mat are divided by means of selective transistors, the disturb resistance of the memory cells can be improved.

    Abstract: In order to form a more homogenous heat generating resistive layer, the present invention provides a method of manufacturing a substrate for an ink jet recording head having a support which has an insulative layer on its surface, a pair of electrode layers disposed on the surface of the support, and a heat generating resistive layer which continuously covers the pair of electrode layers and a section between the pair of electrode layers. The method includes the step of forming an electrode layer on the support and the step of forming the pair of electrode layers by etching the electrode layer. In the step of forming the pair of electrode layers by etching the electrode layer, by etching a surface portion of the insulative layer positioned between the pair of insulative layers, a recess is formed in the surface portion of the insulative layer.

  • Publication number: 20080277379
    Abstract: A filter capable of separating or filtering micro foreign particles in a flow passage is provided. A first mask and a second mask are formed on a silicon substrate by dry etching. Before performing the dry etching, a resist of the first mask is subjected to a heat treatment performed at a temperature equal to or higher than a glass transition point. A resist of the second mask is not subjected to such a heat treatment. This processing simultaneously forms in the substrate a groove portion and a wall having a hole that is located in the groove portion. A silicon material located beneath a wide portion of the first mask remains as a wall portion separating the holes.
