To provide a stencil mask that contamination generating because a material layer set in the surface of a stencil mask is sputtered by a charged particle beam can be-prevented and a method of producing the same. A stencil mask has a thin film having an aperture pattern and a method of producing the same, and a stencil mask and the method of producing the same has an aspect that a material layer having heat conductance higher than that of a thin film is set in the region except for a portion of outer edge of the aperture pattern in the side of a principal surface of a thin film.

To provide a stencil mask that the heat generated in the surface of the stencil mask can be radiated to a supporting substrate supporting a portion around the edge of a thin film quickly and a method of producing the same. A stencil mask has a thin film having an aperture pattern and a supporting substrate supporting a portion around the edge of a thin film and a method of producing the same, and a stencil mask and the method of producing the same has an aspect that a plug that having heat conductance higher than that of a thin film and a supporting substrate is embedded in a state of contacting a thin film and reaches inside of a supporting substrate.

An alloy consisting predominantly of lead and containing 0.1 to 3.0% by weight of tin, 0.1 to 0.3% by weight of arsenic and 0.01 to 0.1% by weight of aluminum or copper. The alloy may further contain 0.002 to 1.0% by weight of cadmium. The alloy is useful for grids, inter-cell connectors and poles to provide lead-acid batteries less prone to self-discharge and capable of withstanding over discharge.

In a semiconductor integrated circuit in which an element isolating insulation film is provided on a substrate, an isolated Si region in the substrate is a shape composed of straight lines which form four sides and circular arcs which form four corners. Further, the adjacent Si regions share element isolating insulation films, and the adjacent Si regions are separated by one element isolating insulation film. Furthermore, widths of the element isolating insulation films are the same in a chip pattern. When the width of the element isolating insulation film is set to a, and a curvature radius of curved lines at four corners of the Si region is set to r; the width a and the curvature radius r are determined so as to satisfy conditions of r>0.7a in the case where the element isolating insulation films are intersected only in a cross shape, and r>1.5a in the case where the element isolating insulation films include a portion intersected in a T shape.

In a transistor of a structure where a bonding pad formed on the surface of a chip and an end portion of a lead terminal are connected by a bonding wire, by forming the bonding pad to be long and narrow so that its length is parallel to a straight line between the bonding pad and the terminal end. The bonding pad and the terminal end are connected along the shortest line The width of the bonding pad is reduced to a minimum.

摘要:
A semiconductor device includes a semiconductor substrate having an active layer in which an element region and a contact region are formed, a support substrate supporting the active layer, and a buried insulation layer interposed between the active layer and the support substrate. A transistor element is formed in the element region, the transistor element having a transistor buried impurity layer formed within the active layer. The semiconductor device further includes a substrate contact having a contact buried impurity layer formed within the contact region and a through contact extending from the surface of the active layer to the support substrate through the contact buried impurity and the buried insulation layer, the contact buried impurity layer being in the same layer as the transistor buried impurity layer.
