RESISTOR AND TRIMMING METHOD THEREOF

摘要

PURPOSE:To realize a low-resistance region and to facilitate trimming by forming a for at least one of a pair of electrodes interdigitally on an insulating substrate. CONSTITUTION:An underglaze layer 2 is formed on a substrate 1. A pair of primary electrodes films 3a and 3b are provided on both end parts of the underglaze layer 2 so that the films are overlapped on the parts of the underglaze layer 2. A resistor film 5 is provided so that the film 5 is overlapped on the tip of a secondary electrode film 4 having the interdigital part and the film 5 is connected to the primary electrode 3b. The interdigital part is cut with a trimming groove 6 so as to obtain the intended resistance value. Trimming 7 is further performed in the resistor film 5 so as to adjust the resistance value finely.
