Variations in the temperature of a substrate in coating forming apparatus are measured by interferometrically investigating variations in the substrate thickness due to thermal expansion. Visible, ultraviolet or infrared light from a laser 21 passes through a window 12 into a vacuum deposition enclosure 11 and is reflected on to a substrate 17. Light reflected from or transmitted through the faces of the substrate interferes causing variations in intensity of the light received by photo-cell 25 each change from maximum to minimum intensity corresponding to a predetermined change in temperature. The transmitted interference fringes may be detected by a photo-cell 26 and indicated or recorded. The thickness of the layer being deposited may also be determined by detecting the interference of the light reflected from the front and back of the layer. If the angle of incidence of the light is suitably chosen, variations due to temperature changes may be distinguished from superimposed variations due to layer build up by their different amplitudes.

Abstract: 1290400 Forming epitaxial layers SIEMENS AG 16 July 1970 [17 July 1969] 34452/70 Heading BIS An epitaxial layer is formed on a substrate by epitaxial growth from a non-stoichiometric melt. The melt 3 is contained in a cylindrical tube 2, heated from outside, which consists of a thick-walled tube 4 closed at the lower end by the terminal section 7 of a cooling rod 5. Between the end face 11 of the section 7 and the melt 3, the substrate 6 is mounted. The interface between the substrate 6 and the surface 11 is designed so that more heat is conducted away from the, otherwise hotter, periphery than from the centre of the substrate, so giving substantially no temperature gradient across the face of the substrate. This is done in the illustrated embodiment by means of a blind bore 8 at the centre of section 7; alternative ways are to provide the supporting surface and/or that side of the substrate adjacent to it with a lapped flat finish or to provide an insulating wafer, of some material such as quartz, located at the centre of the support. The invention is specifically disclosed for the production of gallium arsenide layers with or without one or more dopants such as silicon or germanium/tin or a gallium arsenide support. A shielding gas, preferably hydrogen or nitrogen, is preferably used during epitaxial growth.
