In this study, we propose scandium as a promising materials for hard mask formation in micro and nanoelectronics. It is well known that metals are very resistant to SF 6 - O 2 plasma and, in principle, can be ideal masking materials. [18] Web1 jul. 2016 · This class of materials can be formed by small clusters of metal-oxide organic particles without the need for any of the additional molecular species (i.e., organic …
Webmask can achieve higher etching selectivity to resist than Cr does, and thus is easier to pattern by lithography followed by direct dry etching pattern transfer; and at the same time, for further pattern transferring into the substrate notably silicon, the patterned Cr 2O 3 is as efficient as metallic Cr as the inter-mediate hard mask material. Web4.2.2.3 Soft lithography. Soft lithography is a direct pattern transfer technique. The term “soft” refers to an elastomeric stamp with patterned relief structures on its surface. Polydimethylsiloxane (PDMS) has been used successfully as the elastomeric material. PDMS exhibits unique properties suitable for this purpose.
