Title: Forming potential contrast image in integrated circuit
Inventor: YAMAGUCHI AKIRA
IPC: H01L21/66
Filed: 1984-07-03
Abstract: PURPOSE:To enable the observation of a clear potential contrast image, by applying an alternating current signal in the specific frequency range to the signal line of an integrated circuit. CONSTITUTION:As an alternating current signal in frequency range of 1 or more Hz and 100 or less KHz is applied to the signal line of an integrated circuit, the charge on the insulation protective coating of the integrated circuit is diffused without storage by electron beam irradiation on the surface of the integrated circuit. Furthermore, the interlayer leakage of the integrated circuit is relieved in said frequency range. In other words, a clear potential contrast, image can be obtained for a long time. Therefore, this can be favorably utilized for the electron beam testing method for observing the potential contrast image of secondary electrons while operating an integrated circuit in a scanning electron microscope and for analyzing the behavior of each part of the integrated circuit.

Abstract: PURPOSE:To obtain the bulk crystal of a multielement compd. semiconductor having a uniform compsn. and large size by moving a source flat plate for solute replenishment which comes into contact with a melt in the aperture at the bottom of a boat and executing liquid phase growth while changing the position of said flat plate in contact with said melt. CONSTITUTION:DC current is passed through a positive electrode 9,, a conductor 11, the melt 3, the source flat plate 4, a metal contact 13, a conductor 12, and a negative electrode 10 to effect the resistance heating of the flat plate 4. Further, the contact surface of the melt 3 and the flat plate 4 is heated by a Peltier effect. The position where the solute is replenished from the flat plate 4 to the melt 3 is successively changed in parallel with the progression of the epitaxy on a substrate 7 to maintain the specified characteristic of the flat plate 4 surface as the solute is eluted. The stable heat generation is thus generated in the flat plate 4 by passing always the stable current thereto to prevent the elution conditions from changing with time. The solute replenishment is stably executed over a long period of time. The epitaxy of the multielement liquid crystal having the uniform compsn. is, therefore enabled.
