First wirings are disposed along a straight line in one row or one column of memory cell arrays. A second wiring is disposed above the first wirings and transmits a signal from one end of the second wiring to the other end thereof. Contact plugs connect the first wirings and the second wiring to each other. The first wirings are connected to a plurality of successive memory cells among all the memory cells in the row or column to which the first wirings belong. In case such an LSI is manufactured and defect analysis is made to thereby form an FBM, it is decided that the contact plugs connecting the first wirings to the second wiring are disconnected when a plurality of successive memory cells in one row or one column. Thus, a plurality of defects are expressed by the use of different categories.

A failure analyzing method using a failure-analyzing semiconductor device includes a first step of manufacturing a semiconductor device adapted for product in predetermined numbers during a first interval and a second step of manufacturing a failure-analyzing semiconductor device in predetermined numbers every second interval during the first interval. The first step includes a step of forming memory cells in a first semiconductor substrate. The second step includes a step of forming memory cells in a second semiconductor substrate and a step of forming first and second digitated interconnections at the same level above the second semiconductor substrate, which are connected to the memory cells and arranged so that the fingers of each of the first and second interconnections are interleaved with those of the other with a predetermined space therebetween.
摘要:
A production process of a wax pattern having a core, which is used for casting a product having a complicated hollow portion, comprising the steps of: producing two or more wax shells each having a contour of an external surface of a desired casting; and combining the wax shells with a core to obtain a wax pattern having a hollow portion between the wax shells and the core. Using the method, the occurrence of breakage of the core during dewaxing or production of the pwax pattern is extremely reduced, and a lowering in yield rate due to the breakage of the core is remarkably ameliorated.

摘要:
A soft packaged sealed battery is contained in an airtight container. The airtight container is decompressed and images of the surface shape of the sealed battery in the airtight container before and after decompression are captured by a CCD camera or the like. Whether or not airtightness of the sealed battery is maintained is determined based on a change in the captured images, e.g. a change in the surface shape appearing as luminance differences of pixels. By this determination method, highly accurate airtightness determination is realized by eliminating the influence of invisible fine creases on a sealed battery surface.

Provided is a process for improving alloy properties which can improve the high-temperature ductility of a Ni-base heat-resisting alloy while maintaining its excellent high-temperature strength and weldability. Specifically, it relates to a process for the heat treatment of a Ni-base heat-resisting alloy having a specific composition which comprises the steps of subjecting the alloy to a first-stage solution treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy to a second-stage solution treatment temperature at a specific cooling rate; subjecting the alloy to a second-stage solution treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy rapidly to room temperature at a specific cooling rate; subjecting the alloy to a stabilizing treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy rapidly to room temperature at a specific cooling rate; and subjecting the alloy to an aging treatment by keeping it at a specific temperature for a specific period of time.
