Ultrapure Chemicals

The manufacture of very small electronic components referred to as semiconductors category includes devices such as transistors, capacitors, resistors, diodes, LED and photocells. The different types of devices can be integrated together to form integrated circuits, or VLSI (Very Large Scale Integration) devices such as microprocessors and random access memory (RAM). The high purity processes require the use of equally high purity chemicals stripping, etching, buffering and rinsing. Some of these processes utilize potentially hazardous or aggressive chemicals and chemical mixtures, all of which must filter to nanometer levels to ensure the quality of the devices and high yield. Furthermore, these processes may require temperature in excess of 150C which will limit the processes to materials composed only of fluoropolymers such as PFA and PTFE.
