    • A circuit having a precision passive circuit element, such as a resistor or a capacitor, with a target value of an electrical parameter is fabricated on a substrate with a plurality of independent parallel-connected passive circuit elements. The plurality of passive circuit elements are designed to have a plurality of values of the electrical parameter which are spaced or offset at or around the target value of the electrical parameter, such as three circuit elements with one having a value at the target value, one having a value above the target value, and one having a value below the target value. Each passive circuit element also has a fuse in series therewith. A reference calibration structure is also fabricated, which can be a passive circuit element having the target value of the electrical parameter, in a reference area of the substrate under the same conditions and at the same time as fabrication of the plurality of passive circuit elements. The actual component value of the reference calibration structure is then measured, and based upon the measurement a single precision passive element of the plurality of parallel passive circuit elements is selected by blowing the fuses of, and thus deselecting, the other independent parallel connected passive circuit elements.
    • 在具有多个独立并联无源电路元件的基板上制造具有目标值为电参数的精密无源电路元件(例如电阻器或电容器)的电路。 多个无源电路元件被设计为具有电参数的多个值,其在电参数的目标值处或周围被间隔或偏移,例如具有值在目标值的三个电路元件,一个 具有高于目标值的值,并且具有低于目标值的值。 每个无源电路元件还具有与其串联的保险丝。 还可以在相同条件下的基板的参考区域中以及在制造多个无源电路元件的同时,制造参考校准结构,其可以是具有电参数的目标值的无源电路元件。 然后测量参考校准结构的实际分量值,并且基于测量,多个并联无源电路元件中的单精度无源元件通过吹入另一个独立并联无源电路的熔丝并因此取消选择来选择 元素。
