  • Method of fabricating high accuracy embedded resistors in flex substrates
    Patent number: 12690199
    Abstract: A method comprising: forming a polyimide layer; forming a thin film resistor on the polyimide layer; forming, on the thin film resistor and the polyimide layer, a metallization layer that includes metal contacts on opposing ends of the thin film resistor but leaves an exposed surface of the polyimide layer; baking the polyimide layer, the thin film resistor, and the metallization layer to remove water from the polyimide layer; forming, on the exposed surface of the polyimide layer, a hydrophobic moisture barrier layer that prevents absorption of water into the polyimide layer to avoid blistering of the thin film resistor during subsequent laser trimming of the thin film resistor; and laser trimming a resistance of the thin film resistor between the metal contacts.
    Type: Grant
