Patent ID: 7165315

Claim:
A method for manufacturing a resistor, said method comprising: forming a plurality of pairs of top electrode layers and a plurality of resistor layer on a top face of an insulated substrate sheet, said top electrode layers and said resistor layers being electrically coupled; applying trimming for adjusting a resistance in said resistor layers between said plurality of pairs of top electrode layers; forming a protective layer for covering at least said plurality of resistor layers; forming a plurality of first slit dividing portions for dividing said insulated substrate sheet such that a plurality of groups of a pair of top electrode layers and resistor layer exist on said insulated substrate sheet; disposing a mask on a rear face of said insulated substrate sheet on which said plurality of first slit dividing portions are formed; forming a plurality of pairs of side electrode layers by sputtering on a rear face of the insulated substrate sheet and an inner face of said plurality of first slit dividing portions while said mask being disposed; removing said mask from the rear face of said insulated substrate sheet after forming said side electrode layers; and forming a plurality of second dividing portions perpendicular to said first slit dividing portions for dividing the insulated substrate sheet into discrete substrates by separating said plurality of groups of top electrode layers, resistor layer, and side electrode layers to individual groups.
