Merck was first to develop liquid metalorganic bulk delivery systems (EpiFill™) and continuous liquid level sensors (EpiSensor™) to enable customers to increase throughput, decrease tool downtime and maximize source utilization. Unmatched expertise in high-volume manufacturing and proprietary purification technology ensure chemistry is delivered to the tool with batch-to-batch consistency.

Chemical supply from the market leader will continue to be technology-driven by dedicated people focusing on customers. Our capability to supply and delivery technologies and ensure systems-wide quality assurance ensure cost effective solutions to chemical purchasing.

Facilities strategically placed throughout the world offer proven logistics performance and guarantee continuity of supply. Merck's dedication to total quality management does not go unnoticed by customers. Computerized order tracking, state-of-the-art cylinder preparation and transfill processes, as well as analytical instrumentation capable of measuring the lowest detection limits in the industry contribute to our customers recognizing Merck as a leader in the supply of metalorganics to the CS industry.

Merck has supplied products and services of the highest standard and consistency within agreed specifications for over 20 years. We are the quality leader in the compound semiconductor industry and our choice and service is now even better.
