Patent ID: 7059041

Claim:
A method for producing at least one thin-film resistor element and at least one capacitor element on a substrate, comprising 1a) successively depositing on the substrate ( 2 ), which is passivated, if appropriate, a first high-resistance resistor layer ( 3 ), on the latter a second low-resistance resistor layer ( 4 ) and on the latter a contact layer ( 5 , 7 ), which is provided for electrodes and terminals, 1b) producing structures ( 71 , 72 , 73 , 74 ) for terminals and bottom electrodes in the contact layer ( 5 , 7 ), 1c) separating components by isolating regions being etched free, 1d) applying a first insulator layer ( 9 ) over the whole area on the contact layer ( 5 , 7 ) patterned according to 1b) and the resistor layer ( 4 ), 1e) producing structures ( 11 a ) for first capacitors in the form of openings in the first insulator layer ( 9 ) above bottom electrodes produced according to 1b), 1f) depositing a second insulator layer ( 13 ) over the whole area on the structures ( 11 a ) produced in 1e), and 1g) producing top electrodes ( 141 , 142 ) for capacitor elements in a metallization layer lying above the second insulator layer ( 13 ).
