Patent ID: 6998321

Claim:
A method for forming an inductor in a semiconductor device, comprising the steps of: forming an inductor formation frame layer in which a lower photoresist layer, an intermediate anti-exposure layer and an upper photoresist layer are sequentially stacked, on a substrate in which a lower electrode is formed; patterning the upper photoresist layer by means of an exposure and development process using a first mask; etching the exposed portion of the intermediate anti-exposure layer by means of an etch process using the patterned upper photoresist layer, thus forming a partial via hole; patterning the lower photoresist layer exposed through the upper photoresist layer and the partial via hole by means of an exposure and development process using a second mask, thereby forming trenches and a via hole; and filling the trenches and the via hole with an inductor formation material and then stripping the inductor formation frame layer.
