Photovoltaic Industry
The term Photovoltaic is used to describe the conversion of radiant energy, mostly solar energy, into electric energy.
The manufacturing of wafers made from pure silicon is located in the value chain for the manufacturing process of the modules of photovoltaic systems. Silicon blocks are sawed for the production of the ultra-thin silicon wafers. For this process, the so-called slurry is essential as an abrasive and cooling element. This cutting liquid is contaminated and used up during the sawing process. We designed the service of SiC Processing for the wafer producing companies and we provide them with conditioned and therefore ready-made slurry.
Semiconductor Industry
The Semiconductor Industry deals with the industrial manufacturing of micro-electronic components and assemblies, primarily made of semiconductor materials. This industry also utilizes pure silicon – in this case exclusively monocrystal silicon – for production, which is then melted and drawn into silicon blocks or ingots. These ingots are sawed into wafers using wiresaw technology and slurry. The reconditioning process of SiC Processing in this field can be compared to the process used in the photovoltaic industry. Semiconductor wafers usually tend to be much larger than photovoltaic wafers. These relatively large wafers are only divided into small semiconductor chips following a subsequent stage of production, after they have been fabricated by the semiconductor chip manufacturers. Wafers for the semiconductor industry must satisfy particularly stringent quality requirements and therefore require a particularly high-quality sawing process.
