Title: Pattern exposure device
Inventor: ITO TETSUO
IPC: H01L21/30
Filed: 1989-09-01
Abstract: PURPOSE:To increase effective focal depth, and to improve yield of the manufacture of an integrated circuit element by similarly imaging the image of a photo- mask on a plurality of imaging faces in the direction of an optical axis. CONSTITUTION:When each wavelength is represented by lambda1-lambda5, the images of a photo-mask 7 are formed in a multiple shape in the vertical direction by imaging faces 9-13 for respective wavelength. Angular difference DELTAtheta14 is generated in the angles of refraction of the loci of rays for each wavelength. When a refractive index to the wavelength lambda3 is represented by (n) and the difference between the refractive index for the wavelength lambda1 and the refractive index for the wavelength lambda5 is DELTAn, formula ¦DELTAf¦=fo¦DELTA¦=fo¦DELTAn/(n-1)¦ holds. Since the difference DELTAn of the refractive indices is increased generally over the wide wavelength distribution range of a light source after passage through an interference filter, dispersive power DELTA is improved. Accordingly, the half-value width DELTAlambda of the interference filter is widened, thus spreading the range ¦DELTAf4k of the change of focal length, then deepening effective focal depth.

Title: Structure of semiconductor
Inventor: YAMAZAKI ATSUSHI
IPC: H01L21/316
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To absorb the impact caused by the pressure and the protruding material from the outside by breaking its own film by providing grid-shaped or many grooves in the structure of an insulating covered film. SOLUTION: For insulating film 6, silicon dioxide, phosphorus added silicon dioxide, silicon nitride and polymide, which are not specially specified, are used. The uppermost film layer, i.e., the insulating film 6, are independent to each other. The tension in the lateral direction and the compression are very minute. The insulating covered film is patterned after the film forming by using photo-lithography. The intended structure is obtained by wet or dry etching. As the structure of the insulating covered film, the case wherein many grooves are provided randomly can be used in addition to the grid shape. By providing the grid shape or many grooves, the impact caused by the pressure and the protruding material from the outside can be absorbed by breaking its own film.  Furthermore, since the stress of the film itself can be ignored, the effect of the lower layer to a metal wiring 4 does not occur. Thus, the cost is reduced, and the reliability can be improved.

Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide superior adhesion to an oxide such as a transparent electrode, while improving the oxidation resistance by depositing a transition metal element or an alloy, which is not solid soluble nor fused into a matrix. SOLUTION: A transition metal element or an alloy, which is not solid soluble nor fused in a matrix, is deposited in a surface of an electrode which is composed mainly of Cu so as to improve the electrode surface without increasing the electrical resistance. For example, in the case of depositing the surface transition element with heating, in an electrode formed of a glass substrate 1, an ITO film 2, a deposited metal layer 3 and Cu 4, the transition metal is deposited from Cu 4 so as to coat the surface of the Cu 4 with the transition metal, and a film for protecting a side surface of the electrode is thereby formed. As a metallic element or an alloy to be deposited, one or two kinds or more to be selected from among Cr, Mo, W, V, Nb, Fe, Co are used preferably. An electrode film having superior anticorrosion and low resistivity can be thereby obtained.
