Title: Dry etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1991-06-28
Abstract: PURPOSE:To eliminate the need of using a special material for forming a multilayered resist or intermediate layer so as to prevent the occurrence of re-adhesion resulting from the sputtering of a substrate material by performing dry etching with an etching gas to which SxFx is added after etching the layer of an organic high polymer material formed on the layer of a material containing a high melting point metallic material. CONSTITUTION:After the layer 15 of an organic high polymer material formed on the layer 14 of a material containing a high melting point metallic material, such as W, Ti, Mo, Ni, their compounds, etc., is etched with a mixed gas of O2 and Cl2 dry etching is performed by using a gas prepared by mixing at least SxFy such as S2F2, SF2, SF4, S2F1O etc., for example, SxFy with O2. Therefore, no re-adhesion takes place, since the WSi of base wiring 14 is etched.

IPC: H03H9/145
Filed: 1981-11-18
Abstract: PURPOSE:To execute an electrode design of a metallic strip reflector, by deciding (alpha) and d/lambda so that the product of an electrode width duty factor (alpha) of said reflector, and d/lambda which has devided electrode width (d) by surface acousitc wave wavelength (lambda) enters within a range of specified numerical value. CONSTITUTION:In a surface acoustic wave device using a piezoelectric substrate 1 whose electromechanical coupling coefficient is comparatively small, among electrode width duty factor alpha (alpha=w/p, (w) and (p) denote electrode finger width and an electrode pitch, respectively) of a metallic strip reflector 4, electrode film thickness (d), reflected surface acoustic wave waveldngth lambda, stopping band width DELTAf, and its center frequency fO, there is relation of DELTAf/f0=C.alpha.d/lambda, and C=0.6- 0.8. Therefore, in order to satisfy request specifications of DELTAf/f0=0.5-1.2% (alpha) and d/lambda are decided so that an expression 1 holds good. That is to say, since the wavelength (lambda) is decided by the center frequency f0 of the reflector, an optimum value can be selected from among a lot of combinations of (alpha) and (d) for satisfying the expression 1, and the number of degrees of freedom of an electrode design becomes large. Accordingly, it is possible to execute a design which has taken reduction of a cost into consideration.

Title: Image forming device
Inventor: MURANO SHUNJI
IPC: H04N1/06
Filed: 1992-06-17
Abstract: PURPOSE:To always make a distance between the inner peripheral surface of a base substance and a substrate constant, and to improve focusing performance between an image forming device and a photosensitive film by positioning the substrate at two points or three points by a roller, etc., with reference to the inner peripheral surface of the base substance. CONSTITUTION:The substrate 2 is positioned at about two or three points by the space roller 12 with reference to the inner peripheral surface of the glass base substance 20. The waviness roundness of the base substance 20 or the variation from a complete roundness is absorbed by a spring part 18. When the base substance 20 is deformed, the spring 18 is elongated/contracted in accordance with the deformation and absorbs it. Therefore, the roller 12 always abuts on the inner peripheral surface of the base substance 20, and the distance between the substrate 2 and the photosensitive film 22 is made constant at the points where they are positioned by the roller 12. When the base substance 20 is deformed between two positions where they are positioned by the roller 12, the image forming device is deformed because the substrate 2 and a lens array 7 have flexibility. As a result, the distance between the substrate 2 and the photosensitive film 22 is always kept constant regardless of the positions.
