    Notes: Abstract We have investigated by liquid-phase epitaxy (LPE) the coalescence of defect-free silicon-on-insulator (SOI) layers. The SOI lamellae grow out laterally from neighbouring seeding windows and spread over the SiO2. In our study, the seeding window edges are straight. The long window edges are parallel and extend in the (111) substrate plane in $$[11\bar 2]$$ direction. Coalescence of SOI lamellae takes place without the formation of defects whenever it begins at one point and then proceeds in directions parallel to the longer edges of the windows in a “zip”-like mechanism. Defect-free coalescence seams reach lengths of up to 150 μm.

    Notes: Abstract We describe the first MOS transistors fabricated in silicon-on-insulator layers, obtained by liquid phase epitaxial lateral overgrowth of Si over SiO2. Growth is performed around 930°–920° C using indium as a solvent. The layers are therefore p-type and have a doping of 4·1016 cm−3. Electron mobilities of 540 cm2/Vs are obtained in the inversion channel; the threshold voltage of transistors with a gate length of 14.1 μm is 510 mV. Our data demonstrate the applicability of liquid-phase epitaxial Si grown over oxidized Si for future use in three-dimensional integrated-device processing.
