High aspect ratio cvd
WebChemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, and high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the … WebInitiated chemical vapor deposition (iCVD) was used to coat the surfaces of high-aspect-ratio (∼80:1) pores with functional polymeric films ranging in thickness between 10 and 150 nm. X-ray photoelectron microscopy and electron microprobe analysis confirmed the presence of the polymer coating along the pore wall. Static and dynamic contact angle …
