PROBLEM TO BE SOLVED: To suppress the solder erosion of a material for an electrode 2 and a bonding material, and to improve the efficiency of a module manufacturing process in a method for manufacturing a thermoelement module 10. SOLUTION: In this method for manufacturing a thermoelement module 10, one of the surfaces of an individual thermoelement 3 and a Cu-containing electrode 2 on one of the surfaces of a first substrate 1a, and the other surface of the individual thermoelement 3 and an Cu-containing electrode 2 on one of the surfaces of a second substrate 1b, are bonded together by using a bonding material whose main component is indium 4. A lamellar, fragmentary, or columnar bonding material having a thickness of ≥50 μm and the surface of the individual thermoelement 3 are successively arranged at room temperature on the electrode 2 on the first substrate 1a, and then a pressure is applied onto the other surface of the first substrate 1a and the other surface of the individual thermoelement 3 at a temperature not lower than the melting point of the bonding material.

PROBLEM TO BE SOLVED: To enable trimming even to a miniaturized resistance element 5 while practically measuring four terminals. SOLUTION: In the trimming method of the resistance element 5, a resistor 2 and an electrode 1 are arranged alternately and the resistance value is adjusted while practically measuring the resistance value by using a probe unit 7 to a group of resistance elements continued in a series connection state. A probe pin 3 for energization of the probe unit 7 is brought into contact with the electrode 1 positioned in both ends of the resistance element group, a probe pin 4 for voltage measurement of the probe unit 7 is brought into contact with each of all the electrodes 1 of the resistance element group, a terminal-to-terminal voltage (V) of each resistance element 5 is measured while making a constant current (I) flow by the probe pin 3 between the electrodes 1 positioned in both ends of the resistance element group and a trimming means is implemented to each resistor 2 and/or the electrode 1 so that V is a prescribed value.

PROBLEM TO BE SOLVED: To enable four-terminal measurement in the measurement of a resistor 6 having conductive protrusions 4 disposed in matrix in a method of manufacturing a resistor in which a plurality of resistive elements 2 are formed on a substrate 11 and the resistive elements 2 having external elements being the conductive protrusions 4. SOLUTION: A method of manufacturing a resistor has a process of measuring a resistive value. In the measuring process probe electrodes 1 abut on the conductive protrusions 4 to measure resistive values of the resistive elements 2 formed between paired conductive protrusions 4. The probe electrode 1 abutting on each of the conductive protrusions 4 is composed of a current electrode 1a for applying a current between the resistive elements 2 and a voltage electrode 1b for measuring a voltage between the resistive elements. Each of the conductive protrusions 4 is inserted between the electrodes 1a and 1b, and abuts on them. In this way, four-terminal measurement can be performed. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To allow four-terminal measurement when measuring a resistor 6 comprising conductive projections 4 ion arranged in matrix. SOLUTION: The manufacturing method of a resistor includes a measurement process for the resistance value. The measurement process is a process for measuring a resistance value of a resistance element formed between a pair of conductive projections 4 by making the conductive projection 4 abut with a conductive pad 1. The conductive pads 1 are distributed with which one conductive projection 4 abuts, in two or more, so as to comprise a pad for energizing a current between resistance elements and a pad for measuring a voltage between the resistance elements, ensuring four-terminal measurement.

It is desirable that material 3 whose resistivity is higher than that of the electrode 1 material is tin 3 or solder. The resistor applied in the manufacturing method suitably is e.g. a low resistor for current sensing. COPYRIGHT: (C)2006,JPO&NCIPI
