Maslov V. Physical and technological basics for development of micro- and nanosized bonding precision units of optoelectronic devices.

The dissertation is devoted to investigation of principles of durability and precision mutual position stability of units. The physical concepts of durability of fragile solid bodies with different structure (crystalline, glass-ceramic, amorphous) were developed. The process of their fragile destruction is critical for the surface microplastic deformation in damaged layers forms at initial stages. New types of micro- and nanosized glutinous and unglue bonding of optical units with high operational characteristics were investigated. The adding of micro- and nanofillers to the silicon organic epoxide glue composition gave possible to vary not only the strength characteristics of the joint, but its thermal diffusivity as well. Glass-ceramics parts bonded by means of the new technology of solid-phase sintering of polished parts with nanosized vacuum-deposited aluminum coating (100-200 nm) are characterized by high mechanical strength. The effect of extreme factors on units changes their relative position only the range of 1 to 10 s of arc. Results of industrial usage and new perspective scientific and technical decisions have shown high efficiency of micro- and nanosized bonding of optoelectronic devices precision components, in particular, for laser and solid wave gyroscopes, IR-devices, mirror systems and LCD screens. Keywords: optoelectronic devices, optical units, damaged surface layer, micro -and nanosize glutinous and unglue bonding.
