| titleOfInvention | LIGHT-FUNCTIONAL COMPOSITION OF AQUATIC BASIC SOLUTION |
| abstract | This invention belongs to the field of microelectronics and is intended for application of thick layer technology and expansion of its potentialities. The composition presented consists of (in mass percentage): fine inorganic aggregate powder (100.0), polymer (9-36), photo-initiator (0.5-3.5), organic disulphide (0.2-2.0), inhibitor of thermal polymerisation (0.01-0.35) and organic solvent (5.5-21.5). This composition is painted over a thin net on ceramic plates, dried, exposed through photo-pattern to ultraviolet rays, areas not exposed to light are washed with a 0.5 % monoethanolamine solution, and the picture remaining on the plate is thermally processed at a temperature of 850 degrees Celsius. The aim of the invention is to increase the resolution of the composition and eliminate its sensitivity to visible light and oxygen in the air. The point of trying to solve this problem is as follows: a polymer, which forms a film and ensures solubility in the water base solutions, is photochemically active, its spatial polymerisation is effectively initiated by the photo-initiator, the one insensitive to a visible part of the spectrum, while side-chains of the polymer with alkyl groups and organic disulphide added in addition neutralize the inhibition effect of oxygen, and it ensures higher resolution of the composition. |
