<p>PURPOSE:To perform a precise trimming by providing a conductor pattern with a laser beam perpendicularly refracted and cutting a thick film resistor therebetween together with an electrode section. CONSTITUTION:The width W of a thick film resistor 1 is formed larger than the length L, and electrodes 6, 6' are led perpendicularly to conductor patterns 7, 7'. Since there is no finishing end, when the resistor film is trimmed along a linear line 8 with a laser beam, in the surface of the resistor film, no crack occurs at the resistor, but the resistor can be stably trimmed, and the drift of the value of the resistor can be suppressed.</p> |
