3D-Micromac brings innovative production system on the market of Chemnitz, 29 may 2013. In June, the 3D-Micromac AG of Chemnitz brings the world’s first machine concept on the market that combines all structuring stages to the integrated series connection with thin-film modules on a platform and in one production step. The new one-stop-patterning method (OSP) structured modules only if all functional layers on the substrate are deposited. This considerably simplifies the production process. Also avoid inaccuracies caused by the calibration and alignment of substrates on different tables, thereby increasing the efficiency by up to 0.8 percentage points. So far, thin-film modules were competitive advantage for thin film manufacturer after each coating step with a laser or a mechanical unit structure, which led to extensive cleaning steps, extended lead times and efficiency losses.

Between the coating and structuring steps modules had several times in the vacuum one and again removed be. 200 To 400 microns wide dead zones caused by inaccuracies”, which were not usable for power generation. The OSP process minimizes these areas, however, to less than 100 microns, simplifies the manufacturing process and increases the efficiency. Our process is a crucial step forward for the entire industry of thin film and shortened the distance to the crystalline competition”, explains 3D-Micromac-Geschaftsfuhrer Tino Petsch. Because the upstream process chain is significantly simplified, entirely new machine concepts are possible. Thus the OSP process is paving the way for innovative and fully integrated production lines.” In the production, 3D-Micromac reverts to a combined procedure of laser – and typography. The company successfully used it for years in other fields of application.

No matter whether from amorphous silicon, cadmium telluride or CIGS the OSP system can be fully integrated into any existing production line and works on all popular formats up to 1,10 x 1.30 Meters. About the 3D-Micromac AG, the 3D-Micromac AG has established itself since its founding in 2002 as one of the leading providers of high-efficient laser micro processing systems as well as innovative coating and printing technologies in the international market. Whether as a stand alone system or as a complete production lines come the plants of 3D-Micromac, for example, in medical technology, the semiconductor industry, in the photovoltaic industry or also in the manufacture of flexible electronic components used. There is also the 3D-Micromac of its customers as a competent partner for the development of new technologies and processes, or custom systems available.
