Patent DE-2753273-A1 (DE)
Inventor: HILL MARTIN J DR
IPC: H01L29/84
Filed: 1977-11-30
Abstract: The objective is to simplify the production of monocrystalline silicon components having shapes which can be produced by mechanical and chemical machining methods only with difficulty. For this purpose, component parts which can easily be produced with the aid of mechanical and chemical machining methods are first prepared and these parts are then joined by crystallisation using thermal migration of a metal which migrates in silicon. To produce a pressure sensor, the monocrystalline silicon membrane (1) is joined to a monocrystalline silicon support (2) by crystallisation. In this process, a 5 to 100  mu m thick aluminium layer (4) is applied to the end face of the support (2). This can be done, for example, by vapour deposition or directly by applying an annular aluminium foil. The silicon parts are heated to the temperature of 700 to 1300 DEG C necessary for the migration by irradiation of light. <IMAGE>
