WebJun 12, 2024 · tions it is desirable to produce more sloped or tapered, resist profiles. One of these applications is for the dry etching of tapered contact holes, where the resist wall profile is replicated in the oxide (1-8). A sloped oxide wall profile is desirable to promote good metal continu- ity and step coverage. WebNov 29, 2016 · However, the tapered resist profile is fabricated by low-cost methods using a conventional mask with linearly variable distanced trenches. After the resist is patterned with this mask, the wafer undergoes a thermal-chemical treatment to convert the resist layer with linearly variable distanced trenches to a smooth tapered structure. Then, this ...
