Planer trimming resistor, its application and manufacturing process

摘要

The device has a substrate (1), a resistive layer (3) and a contact layer (6) on the resistive layer and with higher conductivity than and in contact with it at least at individual points (4). Material can be removed locally (7) above the resistive layer. The contact layer does not extend beyond the edges of the resistive layer. The resistive and contact layers can be strip-shaped with connection contacts at opposite ends of the contact layer. Independent claims are also included for the following: 1. a resistive bridge circuit; 2. a sensor with a deformable substrate and at least one resistance element; and 3. a method of manufacturing a balancing resistance.
