Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for forming a measuring electrode pattern which is free from the restriction of the thickness and warpage of a mask, and can always equally form an electrode of 1 mm<SP>2</SP>or less if necessary, in forming the measuring electrode patterns on a semiconductor wafer by vapor growth epitaxy.  <P>SOLUTION: In this method for forming the measuring electrode patterns, after holes for electrode patterns are formed in aluminum foil equipped with an adhesive layer on one main surface in advance, the aluminum foil is stuck to a semiconductor wafer, and then the electrodes are formed by vapor phase epitaxy. Since this method is free from deformation or delamination by a temperature etc., in vapor phase epitaxy, and free from the wrap around of metal ions. Additionally, since the thickness of the foil is extremely thin, it is possible to form required electrodes only in the holes, and to form the electrodes of 1 mm<SP>2</SP>or less always equally. Not only an electrode pattern but also an electrode shape can be arbitrarily arranged, and the electrode having an arbitrary shape such as an extremely small size can be formed on an arbitrary position on the surface of the wafer.  <P>COPYRIGHT: (C)2004,JPO
