WebAbstract—Amorphous carbon may be used as a hard mask alternative to nitride in conjunction with multiple patterning lithography and line-width trimming applications. … Webmixtures. [16][17] Therefore, a selected masking material should be stable in these conditions. 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]
Wet Scandium Etching for hard mask formation on a silicon substrate
WebIn integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable … Web1 mei 2008 · To conclude, carbon hard mask offers new possibilities for improving lithography resolution. The use of such a mask in association with a capping layer suppresses resist thickness limitations, which allows us to pattern ultra thin resist films. Furthermore, this combination of material enables the transfer and integration of sub 30 … flowline temperature

A hardmask is a material used in semiconductor processing as an etch mask instead of a polymer or other organic "soft" resist material. Hardmasks are necessary when the material being etched is itself an organic polymer. Anything used to etch this material will also etch the photoresist being used to define its patterning since that is also an organic polymer. This arises, for instance, in the patterning of low-κ dielectric insulatio… Web13 sep. 2014 · Hard masks used in lithography processes play a vital role in pattern transfer to the desired substrate.
