Title (EN) FABRICATION OF FILM RESISTOR CIRCUITS
(FR) FABRICATION DE CIRCUITS DE RESISTANCE A COUCHES
Abstract: front page image
(EN)A method of fabricating thin and thick film resistors which results in stable resistance characteristics, ability to withstand high current or voltage and a precise method of trimming small resistors. After the resistor film (20) and contacts (22 and 23) thereto are formed, the resistors are trimmed by a cut (24) along - the length dimension so that the width of the current path is reduced uniformly. The waste portion of the resistor is then separated from the circuit by a cut (2) along its width. Current crowding in the vicinity of the cut is therefore essentially eliminated.
(FR)Methode de fabrication de resistances a couches minces et epaisses ayant pour resultat des caracteristiques de resistance stables, pouvant supporter un courant eleve ou une tension elevee et une methode precise de decoupage de petites resistances. Apres la formation de la couche de resistance (20) et des contacts (22 et 23) sur celle-ci, les resistances sont entaillees par une coupure (24) dans le sens de la longueur de sorte que la largeur du chemin du courant soit reduite uniformement. La partie de dechet de la resistance est ensuite separee du circuit par une coupure (27) dans le sens de la largeur. Un tassement de courant a proximite de la coupure est ainsi sensiblement elimine.
