    摘要: Fabrication of an integrated circuit includes forming a photoresist layer over a substrate. Target regions defined on the substrate are exposed using a reticle that defines a first exposure window for a first doped structure of a first type; the first exposure window has a first plurality of openings and a first plurality of dopant blocking regions. A respective exposure dose for each of the target regions is determined by an exposure map and provides controlled variations in the size of the first plurality of openings across the plurality of target regions. Subsequent to the exposure and to developing the photoresist, a dopant is implanted into the substrate through the first plurality of openings.

    摘要: A thick-film resistor in a thick-film printed substrate, the resistance of which is maintained at an appropriate value, is disclosed. In a thick-film printed substrate formed by printing a thick-film conductor and a resistor of lanthanum boride type on a ceramic substrate and then sintering, an intermediate resistor layer of lanthanum boride type is provided between the thick-film conductor and the resistor of lanthanum boride type. Reaction of glass composition contained in the thick-film conductor is suppressed, and resistance abnormality is prevented during sintering by causing the intermediate resistor layer of lanthanum boride type to be interposed.
