Title: Semiconductor substrate and producing method thereof
Inventor: SATO NOBUHIKO
IPC: H01L21/02
Filed: 1996-10-07
Granted: 2001-05-08
Abstract: A method is provided for producing, with high reproducibility, an SOI substrate which is flat and high in quality, and simultaneously for achieving resources saving and reduction in cost through recycling of a substrate member.  For accomplishing this, a porous-forming step is performed forming a porous Si layer on at least a surface of an Si substrate and a large porosity layer forming step is performed for forming a large porosity layer in the porous Si layer.  This large porosity layer forming step is performed by implanting ions into the porous Si layer with a given projection range or by changing current density of anodization in said porous-forming step.  At this time, a non-porous single-crystal Si layer is epitaxial-grown on the porous Si layer.          Thereafter, the surface of the porous Si layer and a support substrate are bonded together, and then separation is performed at the porous Si layer with the large porosity.  Subsequently, selective etching is performed to remove the porous Si layer.

Abstract: A capacitor structure for an integrated circuit and a method of fabrication are described. The capacitor structure is defined by layers forming interconnect metallization and interlayer dielectrics. The latter are relatively thick, and provide high breakdown voltages. Multilevel metallization schemes allow for a stack of a plurality of electrodes to be provided. The electrodes may take the form of stacks of flat plates interconnected in parallel so that the capacitance is the sum of capacitances of alternate layers in the stack. Advantageously each electrode comprises a main portion (56, 60, 64, 68) and a surrounding portion (57, 61, 65, 69) having the form of a protecting ring (e.g. 57), coplanar with the main portion of the electrode. The ring prevent s thinning of the dielectric near edges of electrode during fabrication, to improve control of breakdown voltages for high voltage applications. Alternative electrode structures employing a plurality of interconnected fingers, and particularly a configuration having interdigitated fingers, are provided to increase the capacitance per unit surface area. Parallel electrode fingers are stacked in vertical alignment, or offset, and interconnected to provide vertical, horizontal or inclined stacks having different patterns of polarities, thereby formingcapa citors of various configurations. The capacitor structures have particular application for high voltage (>100V), low leakage and high frequency (MHz/GHz) applications.

Abstract: A silica glass fabrication method. The method includes the steps of adding silica and a dispersant to a premix solution obtained by dissolving a monomer for acrylic resin and a cross-linking agent in a distilled water, and dispersing themixed solution, and adjusting the pH of the mixture, to form a sol; removing airbubbles from the sol, and then aging the sol; adding a polymerization initiator to the aging-treated sol, and adjusting the pH of the reaction mixture; pouring thereaction mixture into a mold, aging the mixture in an incubator at a high temperature and then gelating the resultant; aging the obtained gel, demolding the aging-treated gel, and then drying the demolded gel; thermally-treating the dried gel to remove organic substances from the gel; and performing a hydroxy group elimination reaction and a sintering reaction on the gel from which organic substances have been removed. Therefore, a high purity silica glass tube, in which cracking after drying scarcely occurs and shrinking ratio is markedly low, can be obtained. Also, a large silica glass tube can be manufactured by this fabrication method.

Abstract: A three-layer asphalt composition shingle where the top layer is of a full width, a middle layer is less than the full width, and a bottom layer has a width shorter than the middle layer. The middle and top layers of the shingle have tabs and cutouts. The tabs of each such layer generally differ in some feature. Moreover, the corresponding tabs between the middle layer and top layer also differ with respect to some feature, such as a lengthwise size, a widthwise size, shape or in color.      Each of the three layers includes color zones, and often plural color zones. The different tab features and the different color features of the various layers provide a high degree of randomness to enhance a visual appearance to a roof shingled with such type of shingles.

Abstract: The invention relates to an assembly with a lower steering arm having a strut 1 and an attaching end 16. To achieve a cost-effective design while at the same time reducing the play between the attaching end 16 and the end of the strut 1 received therein, the attaching end 16 consists of a base member 18 and a cover 19. In the base member 18, there is supported the blocking pawl 34. The cover 19 is welded to the base member 18 and comprises a stop face 30 for the end face 10 of the strut 1, so that any tolerances in the region of the base member 18 provided in the form of a forging do not affect the position of the stop face 30. The latter can be aligned when connecting the base member 18 and the cover 19.      Because of its setting contour, the actuating lever 43 can be used for both the right-hand and the left-hand lower steering arm.
