Yield improvement in critical processes

Offentlig prosjektsammendrag

The Quartz Corp (TQC) is a major supplier of High Purity Quartz, sourced from our sites in Spruce Pine (USA) and Drag (Norway). Our products are used in quartz crucibles for solar and semiconductors industry, quartz glass, optical fibers and other high tech products. As stated by it's name, purity is critical for High Purity Quartz. Quartz produced by TQC has a very low impurities, it is mostly SiO2, silica oxide. Production of high purity quartz involves special skills and technologies. The quality requirements are very demanding and processing cost for maintaining quality is high which makes yield an important component for sustainable development. In general in any process yield and quality are interdependent i.e increase in yield has negative effect on the quality and vice versa. So it is very important that any change in process to improve yield should not have any negative effect on the quality.
