After accumulating a BPSG film layer on a silicon substrate, a first Al--Si--Cu film layer, a W film layer and a second Al--Si--Cu film layer are successively accumulated on this BPSG film layer. A resist pattern with wide-width and narrow-width pattern portions is formed on the second Al--Si--Cu film layer. The wide-width pattern portion is provided at a position corresponding to a contact for connecting a first-layer metallic wiring and a second-layer metallic wiring, while the narrow-width pattern portion is provided at a position corresponding to a wiring portion for the first-layer metallic wiring. After applying first etching on the second Al--Si--Cu film layer with a mask of the resist patter, second etching is applied on the W film layer. Thereafter, by applying third etching, the resist pattern remaining on the first-layer metallic wiring is removed and the first Al--Si--Cu film layer is transfigured into a tall metallic film portion and a short metallic film portion. After accumulating an inter-layer insulating film layer on the first Al--Si--Cu film layer, etchback is applied on this inter-layer insulating film layer until the top of the tall metallic film portion is bared. Then, the second-layer metallic wiring is formed on the inter-layer insulating film layer so that the second-layer metallic wiring is connected with the tall metallic film portion.

A stripe-color filter for spatial color encoding in a color TV camera, having a striped semiconductor filter-element-layer supported between a transparent substrate layer and a transparent dielectric covering layer. There are further provided a first coating layer of a transparent thin film between the substrate layer and the semiconductor filter-element-layer and a second coating layer of a transparent thin film between the semiconductor filter-element-layer and the covering layer. The refractive indexes of those layers are in the relationship: n.sub.F >n.sub.T1 >n.sub.S and n.sub.F >n.sub.T2 >n.sub.D, wherein n.sub.S represents the refractive index of the substrate layer, n.sub.T1 the first coating layer, n.sub.F the semiconductor filter-element-layer, n.sub.D the covering layer, and n.sub.T2 the second coating layer. Thus, the first and second coating layers act as anti-reflection layers, so that the spectral transmissivity at the semiconductor layer region of the stripe-color filter is improved.
摘要:
A multilayer wiring structure of a semiconductor device having a stacked structure is arranged to restrain reliability degradation due to stress applied to the region of wiring between opposite upper and lower plugs. The rate of overlap of contact surface between upper plug and wiring on contact surface between lower plug and wiring, is small to the extent that no void is generated. The multilayer wiring structure is produced such that no grain boundary is contained in the region of wiring between upper and lower plugs. The difference in thermal expansion coefficient between the material of wiring and the material of upper and lower plugs, is small to the extent that no void is generated.

An integrated circuit having a multi-layered metal wiring structure with interlayer insulating films therebetween. A small cutout is made in a metal wiring when it is desirous to have the metal wiring touch a contact formed in a through hole passing through said cutout. A larger cutout is made in a metal wiring when it is desirous to have the metal wiring remain spaced from a contact formed in a through hole passing through said cutout.

A first electrode and a first insulating layer of electrode insulation are formed on a first semiconductor substrate. A second electrode and a second insulating layer of electrode insulation are formed on a second semiconductor substrate. The first semiconductor substrate has at its surface a pattern of recesses/projections (i.e., a pattern of sawteeth in cross section) at regular intervals in stripe arrangement. Likewise, the second semiconductor substrate has at its surface a pattern of recesses/projections (i.e., a pattern of sawteeth in cross section) at regular intervals in stripe arrangement, wherein the pattern of the second semiconductor substrate has a phase shift of 180 degrees with respect to the pattern of the first semiconductor substrate. The first and second semiconductor substrates are bonded together with their patterns in engagement.
摘要:
A first metallization layer is locally formed on the surface of a semiconductor substrate thereby leaving portions of the semiconductor substrate's surface exposed. A first silicon oxide layer is then formed in such a manner that it covers the exposed portions of the semiconductor substrate's surface and the first metallization layer. This is followed by the formation of an HMDS molecular layer on the first silicon oxide layer. Then, a second silicon oxide is formed on the molecular layer by means of a CVD process utilizing the chemical reaction of ozone with TEOS. Finally, a second metallization layer is locally formed on the second silicon oxide layer.
