Presenting new K-Patents' technology for fab chemicals: K-Patents introduces the Semicon Refractometer PR-33-S.
The PR-33-S is a new addition to the K-patents refractometers for monitoring and measuring the liquid chemical concentrations throughout the whole semiconductor fabrication process, i.e. from chemical supplies down to fab in-line and tool in-situ chemical quality control.
The new PR-33-S is specifically designed for the ultra-clean environments and integrated process tools.
The PR-33-S monitors real-time the chemical concentrations and provides an Ethernet output signal and gives immediate feedback if the monitored chemical is not within the specifications. The concentration is deterrmined by making an optical measurement of the solution's refractive index. The advantage of this principle is that the same instrumebnt can be used to measure any chemical.
The PR-33-S consists of an ultra-pure PTFE (Teflon) sensor and an Ethernet connection, providing thus connectors and cabling that any standard PoE switch can use for transmitting power to the sensor and data to a computer.
The average payback time for this refractometer is 3-6 months.
