Title:
STRUCTURE OF PRECISION CIRCUIT ELEMENT AND METHOD OF FORMING IT
Document Type and Number:
Japanese Patent JP3701877
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a precision circuit element and a method of forming it.
SOLUTION: The circuit element is formed as one part of an integrated circuit assembly. The process of the circuit element provides a nominal value of the circuit element that is near to a desired value. An additional trim circuit element is coupled through a link to the nominal circuit element. The Link is a fusible link or an anti fuse. By fusing and cutting the fusible link selectively or by adding or reducing the trim circuit element by fusing the anti fuse, the nominal value of the circuit element is individuated. In a typical example, a capacitor is used.
