Web30 de jul. de 1999 · In this paper we present growth results of two high temperature CVD (HTCVD) techniques. The first one, developed for epitaxial growth, is a chimney reactor (vertical hot-wall CVD). The second one is an inverted stagnant flow reactor suited for growth rates of interest for crystal growth applications. 2. Web1 de fev. de 2011 · Growth of thick SiC epilayers has been investigated in a horizontal hot-wall CVD reactor capable of growing 3x2-in wafers or single wafer with a diameter up to 100mm. Good uniformity of lower than 3% for thickness and lower than 20% for doping has been obtained on 2-in or 3-in epi wafers with thickness of 60 - 120 μm. Low intentional …
Web4 de nov. de 2010 · Thick, high quality 4H-SiC epilayers have been grown in a vertical hot-wall chemical vapor deposition system at a high growth rate on (0001) 80 off-axis substrates. We discuss the use of dichlorosilane as the Si-precursor for 4H-SiC epitaxial growth as it provides the most direct decomposition route into SiCl2, which is the … WebIn this work many steps concerning the epitaxial layer growth on 4H-SiC are studied, evaluated and optimized to obtain high quality 4H-SiC epitaxy. The processes evaluated have been studied on a Hot Wall CVD reactor. The first step related to the substrate surface etching has been tuned by choosing the H2 flow, temperature and process time at which …
WebAn exhaustive experimental study of the influence of C/Si ratio on voluntary incorporation of nitrogen (N) and aluminum (Al) in 4H-SiC thin films is presented. The films were grown by chemical vapor deposition (CVD) in a horizontal, hot wall CVD reactor on Si- and C-face substrates, under Si-rich and C-rich conditions. Under some conditions the observed … WebA high growth rate SiC CVD epitaxial process has been developed in a horizontal hotwall reactor for thick epilayer growth. The effect of growth conditions on growth rate and thickness uniformity has been investigated. Growth rates up to …
Web1 de jan. de 2006 · In 1986, Mastunami et al. [1] found that single crystalline 6H-SiC can be grown homoepitaxially on off-oriented 6H-SiC (0 0 0 1) at low temperatures (1400–1500 °C). This technique was named “step-controlled epitaxy”, since the polytype can be controlled by surface steps existing on off-oriented substrates.
