Patent ID: 8169772

Claim:
An adjustable thin film capacitor, adapted for adjusting the resulting capacitance value thereof while said capacitor is in operation in a circuit, comprising: respective first and second terminals; and a capacitor array, situated electrically between said respective first and second terminals, said capacitor array comprising a plurality of respectively valued sub-component capacitors, a laser radiation transparent passivation layer covering at least a portion of said array and arranged so that respective of said sub-component capacitors may be removed from the resulting capacitance value of said adjustable thin film capacitor by laser ablation; wherein said sub-component capacitors comprise a base value capacitor and plural parallel coupled capacitors configured such that one or more of the parallel coupled capacitors may be effectively removed from said parallel connection, whereby the resulting capacitance value of said thin film capacitor may be adjusted; and said plural parallel coupled capacitors are coupled by way of fusible links, configured in a capacitive laddering effect, so that selected removal of respective said parallel coupled capacitors correspondingly adjusts the resulting capacitance value of said thin film capacitor.
