摘要
Abstract
Silicon epitaxial layer is a kind of mono crystalline silicon thin film, which deposites on the surface of the polished silicon substrate by using chemical vapor deposition method. In this study,using 150 mm large size silicon polished wafer as the substrate,with epitaxial layer high uniformity was deposited. Combining with epitaxial electrical parameters by using Fourier transform infrared spectroscopy (FT-IR) and resistivity testing apparatus, the relationship between flowing field, thermal field of the planar epitaxial furnance and uniformity of thickness, resistivity was studied. Finally, the epitaxial layer with good surface quality and non-uniformity less than 1% was prepared successfully.关键词
