    摘要: A method is set forth of bonding together two bodies (1, 2), according to which a first body (1) is provided with a flat surface (5) and the second body (2) is provided with a silicon oxide layer (4) with a flat surface (6), after which a connecting layer (7) containing boron is provided on at least one of the two flat surfaces. Subsequently, the two bodies (1, 2) are pressed together at elevated temperature, so that a borosilicate glass layer is formed. According to the invention, a layer of practically pure boron is used by way of connecting layer (7). Among the advantages of this is that the composition of the borosilicate glass layer is exclusively determined by the previously chosen layer thicknesses.

    摘要: A semiconductor device comprising a silicon substrate is provided with semiconductor elements on a first side, a metallization with connection pads for external contact, and a passivation layer which leaves the connection pads of the metallization exposed. The integrated circuit thus formed is also provided with a ceramic security coating having a matrix of monoaluminium phosphate which also leaves the connection pads of the metallization exposed. The protective layer can be deposited so as to have a thickness in the range from 2 to 10 &mgr;m, and hence is suitable for protecting integrated circuits used in smart cards. As a result, the information stored therein is not accessible.

    摘要: The invention relates to an iron having a metal soleplate, which is provided with an anti-friction layer containing an inorganic polymer. To improve the scratch resistance of the anti-friction layer, a hard intermediate layer is provided between the predominantly aluminum part of the soleplate facing the anti-friction layer and the anti-friction layer.This intermediate layer is preferably composed of aluminum oxide which is provided by means of an electrochemical treatment. The use of polymerized alkyl trialkoxysilane, in particular methyl trimethoxysilane, in the anti-friction layer makes it possible to obtain layers which are thicker and hence more scratch-resistant. In such layers, oxidic nano-particles and inorganic color pigments may be incorporated, which cause a further increase of the scratch resistance.
