策が課題となっている。Background of the Technology In devices such as those described above, patterns made of conductors, magnetic materials, etc. are often formed in multiple layers on the substrate. In this case, in order to prevent defects such as cutting of the upper layer or turns, it is necessary to apply a resin or the like after forming the lower layer pattern and perform a flattening process (7° lensing). However, the conventional pattern forming method has problems as described below, in which it is difficult to flatten the pattern, and countermeasures have been a challenge.

易でない。Prior Art and Problems The conventional method for forming grooves and turns generally uses IJ printing technology, which first involves forming I? A layer of material to be patterned is formed on the surface of the substrate, and then a patterned nocturne is formed in the photoresist material using photolithographic techniques on the layer of material to be patterned, followed by a layer of patterned material. It is etched to form a groove. However, in this method, the cross-sectional shape of .gtanine is uniquely determined by the etching method, and the cross-sectional shape cannot be controlled. Therefore, the four-turn cross-sectional shape has a steep pattern side surface, making it difficult to flatten the pattern.

状を制御し得る。According to this method, during the etching process, when the film is removed by etching, the film material re-adheres to the side surfaces of the mask pattern, resulting in a thick mother turn of the mask with a double structure made of different materials with different etching rates. In the etching step of the next AI pattern material layer, the film material layer of the mask pattern is removed during etching because the etching rate is higher than that of the mask mother turn material. The layer will be etched in two stages. Therefore, the cross-sectional shape of the pattern can be controlled by appropriately selecting the material and thickness of the coating.

The side surface of the pattern has a two-stage structure consisting of a portion A1 etched using the coating material layer C' as a mask and a portion A2 etched using the resist pattern B as a mask. The cross-sectional shape of the arm turn AP is compared to the pattern cross-sectional shape AP' (indicated by a dotted line) when etching is performed using only the resist layer and the turn B as a mask without forming the film C, and the pattern width is reduced by the portion of Al. is thick and has a two-step shape, and has a gentle slope.
