Method for controlling electric resistance of a compound-type resistors

摘要

A method for controlling electric resistance of a compound-type resistant material is disclosed in which a laser beam is irradiated on a compound-type resistant material so as to cause a change in its chemical state whereby the specific resistance inherent to the compound-type resistant material is varied thereby to change its electric resistance in an appropriate manner. If necessary, a portion of the resistant material may be cut away by irradiation of a laser beam so as to further control the resistance value of the resistant material in an increasing sense.
