Sapphire and sapphire wafer manufacturing
  • Share

Synthetic sapphire (aluminum oxide α-Al2O3) and sapphire wafers are widely used in microelectronics, optical devices, metallization pastes for solar cells, mechanical and medical engineering and instrument making. The production of many composite materials and nanoheterostructures of gallium nitride, aluminum, and indium also requires sapphire wafers. The wafers are broadly used to manufacture light-emitting and laser diodes, including fifth-generation white LEDs.

Monocrystal grows and processes monocrystalline sapphire and is currently developing metallization pastes for solar cells. The industrial technology involved in sapphire production is based on the enhanced Kyropoulos method. The technology allows for the growth of single crystals with a diameter greater than 300 mm and with a low dislocation density.

Monocrystal currently holds worldwide market shares of 25 percent in synthetic sapphire and 15 percent in aluminum compounds for solar modules, making the company one of the market leaders in electronic materials for high-tech applications.

Cooperation with RUSNANO

The Visual Science Company has cooperated with the RUSNANO Group since 2008, creating a wide range of high quality graphic information materials. Various infographics have been designed to demonstrate the technologies developed and implemented by RUSNANO project companies. The aim of each project is to demonstrate the principle of technology, nanotechnological components of the project and the advantages of the chosen solution compared with analogues.

The work of Visual Science is carried out in a single sheet or slide format. The modular structure of the infographics makes it possible to use it both as a whole piece or as separate components, which is convenient for preparing website illustrations or project reports or publications. Thus one material helps to solve almost all the issues with illustrating the information about the project.

The target audience for these graphics includes professionals in relevant areas, and a wide range of specialists in different fields without a technical background. Scientific accuracy, combined with the optimum degree of generalization allow for communicating equally effectively with target audiences with different background.

All the graphics have been used by the RUSNANO Group for 5 years or more. As usual, the feature of the Visual Science workflow includes the entire spectrum of tasks ranging from analyzing the scientific literature of the project to the preparation of the final graphics on the company’s side that allows saving valuable time of our customers.

Molecular modelling through computer graphics permits plenty of latitude for exercising artistic talent to inform, explain and instruct. Visual Science shows the way with its high quality, accurate, informative graphics that explain even the most complex processes of life.
