Abstract: The invention relates to a method of joining substrates. It is the object of the invention in this respect to join substrates of substrate materials together without having to exert an increased effort for a coating with additional coating processes to be carried out and to be able to achieve a good quality of the join connection in so doing. In the method in accordance with the invention a pretreatment of at least one join surface of a substrate to be joined is carried out in low pressure oxygen plasma prior to the actual joining. On the joining, a contact force acts on the substrates to be joined in the range 2 kPa to 5 MPa and in this process a heat treatment is carried out at an elevated temperature of at least 100° C. and at under pressure conditions of a maximum of 10 mbar, preferably

Abstract: Two substrate pieces are welded together with a focused laser beam. One of the pieces is transparent in the wave length of the laser beam. The two pieces are pressed together so the tops of the roughness of the joining surfaces become level and both a uniform and pocket like air layer is removed from between the surfaces. The focal point of the laser beam is focused in the common boundary surface of the substrate pieces and the pieces are set to movement in relation to the laser beam so that the focal point advances in the boundary surface according to the shape and length of the weld. The energy of the focal point melts the material of the two pieces at the same time. When the melts mix and harden, a weld is formed that joins the pieces hermetically and goes round the third piece(s) isolating it hermetically.

Abstract: In a multilayer ceramic substrate manufactured by a non-shrinking process, a bonding strength of an external conductive film formed on a primary surface of the multilayer ceramic substrate is increased. After a laminate of a multilayer ceramic substrate is formed from first ceramic layers and second shrinkage suppressing ceramic layers, and an underlayer is formed along one primary surface of the multilayer ceramic substrate, an external conductive film is formed on the underlayer. A non-sintering ceramic material powder in a non-sintered state is included in both the external conductive film and the underlayer, and this non-sintering ceramic material powder is fixed due to diffusion of a glass component from the first ceramic layers.
