摘要 |
<p>The invention relates to a method of manufacturing a semiconductor device, comprising the provision of a substrate (1) having a dielectric layer (2) on this substrate (1), a conductive layer (3) on the dielectric layer (2), an inorganic anti-reflection coating (4) on the conductive layer (3), and a resist mask (6) on the inorganic anti-reflection coating (4). The method further comprises the following steps: patterning the inorganic anti-reflection coating (4) by means of the resist mask (6); patterning the conduc tive layer (3) by etching down to the dielectric layer (2); removing the resist mask (6); and removing the inorganic anti-reflection coating (4). According to the invention, the inorganic anti-reflection coating (4) is removed by means of a dry etch, using a polymerizing gas. It is achieved by this that no or hardly any changes in the critical dimension will occur.</p> |
