Entegris, Inc. operates as a developer, manufacturer, and supplier of yield-improving materials and solutions for manufacturing processes in the semiconductor and other high-technology industries worldwide. The company’s products and materials are used to manufacture semiconductors, micro-electromechanical systems, flat panel displays, light emitting diodes, high-purity chemicals (such as photoresists, solar cells, gas lasers, and optical and magnetic storage devices), and critical components for aerospace, glass manufacturing, and biomedical applications. The company sells its products worldwide through a direct sales force and through selected distributors. The company offers a product portfolio that includes approximately 20,000 standard and customized products, which include both unit driven and capital expense driven products. The company’s unit-driven product class includes membrane-based liquid filters, resin-based gas purifiers, wafer shippers, disk-shipping containers and test assembly and packaging products, implant gas storage and delivery systems, copper electroplating materials, advanced precursor materials for thin film deposition and photoresist strip and post chemical mechanical planarization (CMP) or CMP cleaning materials and consumable graphite and silicon carbide components. Segments The company designs, manufactures, and markets its products through two business segments, Critical Materials Handling and Electronic Materials. Critical Materials Handling segment This segment offers a range of products that purify, monitor, and deliver critical liquids and gases to the semiconductor manufacturing process and similar manufacturing processes, as well as microenvironments products to preserve the integrity of wafers, reticles and electronic components at various stages of transport, processing and storage and materials, components and services to a range of customers in the semiconductor industry and in adjacent and unrelated industries. Liquid Microcontamination Control Products Liquid processing occurs during multiple manufacturing steps, including photolithography, deposition, planarization and surface etching and cleaning. The fluids that are used include various mixtures of acids, bases, solvents, slurries and photochemicals, which in turn are used over a range of operating conditions. The design and performance of the company’s liquid filtration and purification products are critical to the semiconductor manufacturing process because they directly reduce defects and improve the manufacturing yield. Primarily designed proprietary filters remove nanometer-sized particles and bubbles from the different fluid streams that are used in the manufacturing process. Some of the company’s filters are constructed with ultra-high molecular weight polyethylene flat sheet membranes that offer improved bubble clearance and gel removal to prevent defects in the wafers that occur if these elements are not removed. The company’s low hold-up volume disposable filters, with flat sheet membranes, use its Connectology technology to allow filter changes in less than a minute, faster than conventional filters, to reduce the amount of chemicals lost each time a filter is changed and to minimize operator exposure to hazardous solvents and vapors during change out. In addition to the filtration of particles from fluids, the company has expanded its offerings for chemical purification, which targets the removal of specific molecules from a process chemical, to improve yield in processes, such as wet cleaning. Microenvironments Products The company’s microenvironment products fall into three sub-categories, such as wafer and reticle handling products, wafer shipping products, and data storage products. The company is a producer of wafer and reticle handling products worldwide. The company offers various products that hold and position wafers as they travel between each piece of equipment used in the automated semiconductor manufacturing process. These specialized carriers provide precise wafer positioning, wafer protection and predictable cassette interfaces in automated fabs. Semiconductor manufac
