Semiconductors - Import export

In the manufacture of semiconductors, agitators are mainly used in conditioning of polishing and cutting suspensions, etchants and other auxiliary chemicals, cleaning solutions, or in chemicals recycling. Requirements placed on stirring systems are extremely demanding. Almost always, clean room conditions prevail, meaning that drives and seals must be designed with no abrasion or leakage. Parts that come into contact with the medium, such as the shaft and stirring element, often have to be produced with metalfree surfaces due to the aggressiveness of the media and the purity requirements. Also in this area, Geppert Ruhrtechnik can look back on a very successful history. All well-known chip manufacturers belong to our client base, as well as the manufacturers of the specialty chemicals used in this field. In addition, our agitators are used in broad solar cell production areas.

Speed matters in inspection, process control, or defect and failure analysis for the microelectronics and semiconductor industry. The faster you detect a defect, the faster you can react. With a large field of view, the DM3 XL inspection system allows your team to identify defects faster and increase your yield rate. Make use of the 30% increased field of view of the unique macro objective. Additionally, the DM3 XL uses LED illumination for all contrast methods. LED illumination provides a constant color temperature and offers real color imaging at all intensity levels. - Increase your yield - Reliably detect insufficient development at the edge or within the center of a wafer - Detect uneven radial film thickness - True-to-life color imaging at all intensity levels - Reproducible results
