MDC Software offers advanced features
Materials Development Corporation Model CSM/Win Semiconductor Measurement Systems offer a comprehensive selection of tests and analyses for photovoltaic device production from starting material characterization to finished device testing. MDC CSM/Win Systems offers capacitance- voltage, doping profiling, and lifetime testing for semiconductor material. Testing for finished devices includes current-voltage tests for efficiency, maximum power, series resistance, shunt resistance, and fill factor. Special tests like Dit, DLCP, and diffusion modeling help the photovoltaic device manufacturer control critical processing steps.
MDC software includes many advanced features not found in typical measurement systems: quantum modeling, measurements of leaky devices, ion implant modeling and analysis, production style program options for unskilled operators, and a 1000 page help subsystem.

Performance Pryolytic Boron Nitride (PBN) material
Morgan Technical Ceramics' Chemical Vapor Deposition Materials business (MTC - CVD Materials) offers its Performance Pyrolytic Boron Nitride (PBN) material for use in manufacturing of the photo absorption layer in thin film photovoltaic (TFPV) cells. Performance PBN is an excellent material for crucibles and evaporation boats used in producing the TFPV cells, as well as for coating graphite heating elements used for material vaporisation. In solar cell production, thin film deposition offers a simpler and more cost effective alternative to using silicon wafers. However, cost of deposition must be reduced and the efficiency of the resulting PV cells sufficiently increased to make solar electricity as inexpensive to generate as carbon-based methods. Use of the PBN material in the TFPV process is considered an important innovation that will make the goal of using solar energy to generate more of the world's electricity

The BrickMaster BM 850
Our objective in wafering is 98 % yield, 95 % uptime at lowest production costs. The new developed wire saw BrickMaster processes multi crystalline silicon ingots into bricks with minimum kerf loss and maximum productivity. The BrickMaster is based on the market proven wire saw technology of Meyer Burger – Swiss Slicing Systems. An outstanding feature is the cutting unit that can be operated entirely separate from and parallel to the production process. While one bricking process is running, at the same time a second cutting unit can be fitted
with wire or maintained. Based on this new process solution the changeover time is three times faster between each cutting process and the productivity is increased up to 10 % compared to the industry. Benchmarking shows that the BrickMaster reduces the consumption of cost-driving consumables remarkably. The material savings per brick result in some: 7 % in consumables and up to 8 % in production cost. The BrickMaster BM 850 offers bricking at lowest cost of ownership.
more attainable. In the TFPV deposition process, precursor vapors are transported from a source vessel into a deposition zone onto a heated substrate to deposit the PV layer. In some instances, solid materials are melted and vaporised from ceramic crucibles or boats to form a flux that is deposited on the heated substrate. It is critical that the ceramic crucible or boat be dimensionally stable and chemically non-reactive to the molten source material. PBN ceramic is an excellent material because of its high corrosion resistance and non-reactivity with the source materials used in PV deposition. The PBN material is highly anisotropic (directionally dependent) in its thermal transport and very resistant to thermal shock. PBN is also an excellent electrical insulator. The material is stable in inert and reducing atmospheres up to 2800°C and in oxidizing atmospheres to 850°C.
Components of the CSM/Win System are chosen from the best capacitance meters and current-voltage meters available and selected to match customer requirements. There are hundreds of possible system configurations and even more when probe stations are included. MDC offers mercury probes for rapid, non-destructive testing, simple probe stations, heated probe stations, and cryogenic probers.
MDC test equipment is used worldwide by semiconductor manufacturers, universities and research institutions. Behind all CSM/Win Systems stands MDC, the company that introduced the computerized C-V plotter over 30 years ago. MDC has the technical support and applications experience to serve you better and a continuing commitment to pioneer semiconductor analysis technology. MDC has the experience to assemble and support the entire system from the tip of the probe to the plot on the screen.
