Abstract:
A method for producing mechanically firm glued connections between opposing surfaces, which surfaces are to be connected by use of a planar surface region of each surface extending over the surface and having a roughness with a small peak-to-valley height, said method comprising the steps of providing two elements with surfaces with planar surface regions having a surface roughness with a small peak-to-valley height t of less than 0.3 .mu.m, one of the two elements being a module selected from a group consisting of microelectronic modules, micromechanical modules and microoptical modules, the surface regions of the one element being a contact surface of a surface segment of the module, and the surface region of the other element of the two elements being a contact surface of a surface segment of a substrate, positioning the surface regions of the two surfaces opposite one another with a spacing between the surface regions extending planarly over the surface regions to form an intermediate space having a small average thickness d of less than 0.3 .mu.m and with an area having a size of at least 20.times.20 .mu.m.sup.2, introducing a hardenable liquid glue having a low dynamic viscosity in the intermediate space, utilizing a capillarv action to spread the thin liquid glue in a planar fashion and then hardening the glue contained in the intermediate space while maintaining the small average thickness d of the intermediate space to form the mechanically firm glued connection between the surfaces.
