Abstract: PURPOSE: To eliminate junction-leakage and achieve information holding for a long time by forming a transistor, for functioning as a switch of a memory cell, and a capacitor, for storing electric charge, from a semiconductor film provided on a main surface of a semiconductor substrate with an insulating film being disposed therebetween. CONSTITUTION: A memory cell is constructed of a transistor, for functioning as a switch of a memory cell, and a stack-type capacitor, for storing electric charge. An insulating film 20 made of silicon oxide is formed on a silicon substrate 1, and the memory cell is provided on a polysilicon film 21 formed on the insulating film 20. Therefore, the memory cell is separated from the substrate 1 by the insulating film 20, and has no PN junction in a node part which has caused leakage in a conventional DRAM cell. The stack-type capacitor is formed also on the insulating film 20, and has no junction with the substrate 1. Thus, junction-leakage in the memory cell is eliminated so that information can be held for a long time period.

A semiconductor thin film magnetoresistance element 6 is obtained by forming two teading-out electrode terminals 4, 5. In this element 6, the element itself has almost 180 deg. rotation symmetry setting the rotation center 7 as the reference. The substrate 1 itself has not always 180 deg. rotation symmetry setting the rotation center 7 as the reference. Thereby the potential arrangement in the right and left turning-back part is symmetric viewing from the leading-out terminals. A point where a current path is almost symmetric is always present in an arbitrary element position.

Abstract: PURPOSE: To qualitatively and quantitatively measure an antigen or antibody in a specimen by adding an enzyme-labelled antigen or antibody to aggregated magnetic particles judged to be positive to react with each other and measuring the activity of enzyme bonded to the magnetic particles. CONSTITUTION: In an indirect aggregation measuring method, magnetic particles to which an antigen or antibody is bonded and a specimen are mixed in a reaction container to be reacted and the magnetic particles in the container are sedimented by a magnet. The inner surface of the reaction container is inclined by 20-40 deg. and the length of the particles flowing out after 1-5min is measured. The specimen wherein the measured length of the particles does not reach definite length by the agglutination due to immunoreaction is judged to be positive. The magnetic particles obtained by removing a supernatant liquid from a particle soln. judged to be positive are washed to be mixed with an enzyme-labelled antigen (antibody) to be reacted therewith.  Further, the magnetic particles are collected by a magnet and, after the unreacted enzyme- labelled antigen (antibody) is removed, the magnetic particles are washed to be subjected to B/F separation and, thereafter, the activity of enzyme bonded to the magnetic particles is measured using a chemoluminescent substrate. By this constitution, the object to be measured in a specimen can be measured qualitatively and quantitatively.
