چکیده

Growth of rough polycrystalline silicon films has been achieved on SiO, surfaces over a broad temperature range () 100 “C!) using SiH, chemical vapor deposition at low pressures (mTorr range), with smaller grain structure and roughness length scale achieved at lower temperatures. Rough morphology over a broad temperature range is attributed to the combination of nucleation-controlled initial growth (on Si02) and domination of growth by surface reaction (cf. gas phase).

High-rate chemical vapor deposition of nanocrystalline silicon carbide films by radio frequency thermal plasma

Silicon carbide films were deposited by radio frequency thermal plasma chemical vapor deposition (CVD) at rates up to several hundred micrometers per hour over a 40-mm diameter substrate. The films were primarily h-phase SiC. Film morphology was characterized by columnar growth terminating in hemispherical surfaces. The average crystallite size as determined by X-ray diffraction line broadening...

Growth front roughening in silicon nitride films by plasma-enhanced chemical vapor deposition

The dynamic roughening of amorphous silicon nitride growth front prepared by a plasma-enhanced chemical vapor deposition is presented. Morphology of the films grown at different substrate temperatures ~from 50 to 350 °C! for various lengths of deposition time was measured ex situ using atomic force microscopy. The dynamic scaling exponents are measured as a;0.77, b;0.40, and 1/z;0.28, and do no...

Hot-Filament Chemical Vapor Deposition of Organosilicon Thin Films from Hexamethylcyclotrisiloxane and Octamethylcyclotetrasiloxane

A nonplasma technique, hot-filament chemical vapor deposition ~HFCVD!, is an alternative method for producing organosilicon films of novel structure. Films are deposited onto room-temperature substrates from the precursors hexamethylcyclotrisiloxane (D3) and octamethylcyclotetrasiloxane (D4) at high rates ~.1 mm/min!. Filament temperature can be used to control film structure, and the limited r...

Control of CVD-deposited ZnO films properties through water/DEZ ratio: Decoupling of electrode morphology and electrical characteristics

In this work, it is shown that variations in the ratio of oxygen to zinc precursors at constant temperature allow changing the surface morphology of zinc oxide (ZnO) films deposited by lowpressure metalorganic chemical vapor deposition, while keeping the sheet resistance and transparency of the layers constant. This allows developing ZnO layers combining interesting properties such as low surfa...

Growth of conformal single-walled carbon nanotube films from Mo/Fe/Al2O3 deposited by electron beam evaporation

We discuss growth of high-quality carbon nanotube (CNT) films on bare and microstructured silicon substrates by atmospheric pressure thermal chemical vapor deposition (CVD), from a Mo/Fe/Al2O3 catalyst film deposited by entirely electron beam evaporation. High-density films having a tangled morphology and a Raman G/D ratio of at least 20 are grown over a temperature range of 750–900 C. H2 is ne...
