ABSTRACTSi1−zGez single crystal layers were grown on Si(iii) by liquid phase epitaxy (LPE) over the entire composition range (0 ≤ x ( 1). Using Sn as solvent all compositions were produced; alloys with compositions 0 ≤ x ≤ 0.75 were obtained using In as solvent; the range 0.75 ≤ x ≤ 1 was covered with Bi solvent. The solvents used, the composition of the solution, the saturation temperature, and the cooling rate, were found to strongly influence the growth morphology.

AbstractWe have investigated the surface morphology of thick SiGe layers grown on Si(100) substrates. SiGe layers containing different Ge concentrations (from 0 to 16 at.%) and having thickness of about 15μm are prepared by liquid phase epitaxy (LPE) method using various growth conditions. The wavelength of undulation of SiGe layers is found to be increasing when we adopt low cooling rates during LPE process. The roughness of the layer does not show any significant change with cooling rate.

Defect-free silicon layers grown on insulators (SOI) are an essential component for future three-dimensional integration of semiconductor devices. Liquid phase epitaxy (LPE) has proved to be a powerful technique to grow high quality SOI structures for devices and for basic physical research. Electron microscopy is indispensable for the development of the growth technique and reveals many interesting structural properties of these materials. Transmission and scanning electron microscopy can be applied to study growth mechanisms, structural defects, and the morphology of Si and SOI layers grown from metallic solutions of various compositions.The treatment of the Si substrates prior to the epitaxial growth described here is wet chemical etching and plasma etching with NF3 ions. At a sample temperature of 20°C the ion etched surface appeared rough (Fig. 1). Plasma etching at a sample temperature of −125°C, however, yields smooth and clean Si surfaces, and, in addition, high anisotropy (small side etching) and selectivity (low etch rate of SiO2) as shown in Fig. 2.
