Abstract
A trimming resistor is manufactured by depositing a resistive layer on a substrate, with a passivation layer having windows, and a contact layer which is in contact with the resistive layer via the windows. Trimming is carried out by interrupting the contact layer at narrow spots or regions. This invention has application for the manufacture of high-pressure sensors.
