Abstract: PURPOSE:To obtain a low-resistance substrate contact by allowing a polycrystalline silicon doped with no impurities to be subjected to chemical vapor growth in a groove and a spacing between grooves each with a fine opening area and then performing vapor diffusion of specified impurities in this polycrystalline silicon. CONSTITUTION:A separation oxide film 5 is formed for an SOI substrate, a separation groove 6 reaching a thermal oxide film 2 through the separation oxide film 5 is formed, and at the same time a groove 8 is formed at a substrate contact region. Then, a thermal oxide film 7 is formed on a side surface of silicon layers 3 and 4 which are exposed at the grooves 6 and 8. Then, the thermal oxide film 2 covering an inner-wall surface of the groove 8 is eliminated by etching. Then, a non-doped polycrystalline silicon layer 11 is deposited and this polycrystalline silicon layer 11 is doped with impurities. Then, a non-doped polycrystalline silicon is allowed to grow and the polycrystalline silicon layer 11 is buried into the groove 8. After this, heat treatment for allowing the introduced impurities to be diffused to the polycrystalline silicon layer 11 is performed.

Abstract: PURPOSE:To exactly execute a measurement of a component even in case when a potential gradient is lowering, by setting the height of a potential gradient value of other component immediately before the height of an objective component, to a difference of height of the potential gradient value, to derive the potential gradient value of the objective component. CONSTITUTION:A sample which has been led into the boundary surface of a leading liquid and a terminal liquid is migrated, each sample component is separated by a difference of its mobility, and also a potential gradient value of each sample component is detected. In this case, in case when each potential gradient value decreases by a distance, the height of the potential gradient from other component of the object component is decided by the rise height (a), (b), (c) from the potential gradient values Hl, A', B',... of other component immediately before the object component. For instance, as for a sample component B, that which has added ''(a)+(b)'' to the potential gradient value Hl of a leading liquid is made a potential gradient value of the component B. By being based on the potential gradient value which has been derived in this way, both the potential unit value and the potential ratio of the component B are derived.

Abstract: PURPOSE:To automatize decision of the output characteristic by determining upper and lower limits of the allowable range of a power source and comparing the power source output, which changes in accordance with the load condition, with upper and lower limit values. CONSTITUTION:If the output of a D/A converter 11 is changed stepwise, an electronic load 3 takes a load current from a power source 1 to be checked. In this case, the output state of the power source 1 is compared with allowable upper and lower limit values fH and fL of D/A converters 12 and 13, which are changed synchronously with the output of the D/A converter 11, by comparators 14 and 15. If the output state is deviated from the allowable range, outputs of comparators 14 and 15 are changed, for example, from '0' to '1' to issue an abnormality signal EOP, and D/A converters 12 and 13 issue alarm signals 1 and 2 respectively, and comparators 14 and 15 stop the sweep operation of D/A converters 12 and 13. In this constitution, the output characteristic of the power source is compared with upper and lower limit values while changing the load state of the power source after the load condition is set preliminarily, thus decided automatically and quickly whether the power source to be checked is good or not.
