According to an embodiment, there is provided an apparatus which quantitatively evaluates a braze bonding length. A radiation emission unit emits radiation to each of a plurality of partial specimens which are obtained by cutting a specimen in a plane perpendicular to a braze bonding length direction. A light generator generates light of an amount corresponding to an intensity of transmissive radiation. An imaging unit photographs this light. A calculator calculates a braze bonding length of each of the partial specimens, from a light amount obtained with respect to each of the partial specimens, based on a correlation between a braze bonding length and a light amount. The calculator further calculates the braze bonding length of the specimen by totaling the braze bonding lengths of the respective partial specimens.

An interlayer insulating film ( ) is formed to cover the polysilicon layer ( ), and a polysilicon layer ( ) is formed on the interlayer insulating film ( ). An interlayer insulating film ( ) is formed to cover the interlayer insulating film ( ). A hole ( M) for a mark to constitute an alignment mark or the like is formed from a surface ( S) of the interlayer insulating film ( ) to the polysilicon layer ( ). The hole ( M) for a mark is larger than a contact hole formed from the surface ( S) to the substrate ( ) but is shallower than the contact hole. Consequently, a concave portion corresponding to the hole ( M) for a mark is formed, with difficulty, on a silicon oxide layer to be subjected to CMP polishing and then become an interlayer insulting film ( ). Therefore, it is possible to prevent a slurry from remaining in the concave portion. Thus, it is possible to obtain a semiconductor device having high reliability without a disadvantage such as a wiring disconnection or the like which is caused by the remaining or scattering of the slurry to be used for a CMP method.

A signal Y outputted from a Y/C separating circuit is supplied to first and second matrices. Signals R-Y and B-Y are supplied to the first matrix through a gain control amplifier (GCA) and are also supplied to the second matrix. The signals Y, R-Y, and B-Y are converted into three primary color signals R, G, and B by the second matrix. From the signals R, G, and B, a skin color component is detected by a skin color detecting circuit and E is outputted. On the basis of E , color components other than the skin color are detected by a color component detecting circuit and E is outputted. E &minus;E is supplied as a control voltage to the GCA. Gains for the signals R-Y and B-Y are controlled. When the video signal indicates the skin color component, the control voltage is set to 0 and the gain is set to 1. When the video signal indicates a color component other than the skin color component, E is generated, the control voltage rises, and the gain is increased. The colors other than the skin color are emphasized and the color contrast is more naturally enhanced.

Video image display apparatus and method

In a foreground/background discriminating circuit based on focusing, a leading edge of a boundary portion is detected from a video signal and a parallax control signal is outputted on the basis of the detected leading edge. Similarly, in foreground/background discriminating circuits based on color differences and based on a luminance, a chroma component and a luminance component of the video signal are detected and parallax control signals are generated on the basis of the detected chroma and luminance components, respectively. In a multiplier, the parallax control signals generated from the foreground/background discriminating circuits are multiplied. In a parallax limiting circuit, a delay amount control signal for a left video signal and a delay amount control signal for a right video signal are formed in a manner such that a binocular parallax amount lies within a predetermined value and within a range of an amount such that the existence of the parallax is recognized clearly.
