Vaporization of critical process chemistries is not an easy task. To begin with, advanced processes are constantly changing and using novel chemistries for which data may be limited. In some instances, researchers may need vaporization equipment for chemistries whose identities they don’t want to disclose. Once the chemical properties are determined, the job of balancing liquid flows, carrier gas flows, upstream and downstream pressures and materials compatibility can start. Often a carrier gas is required, and the carrier flow must be carefully calculated and controlled during process. The temperature of the vaporizers is also key – balancing the required temperature vs the potential to heat-induced damage to the liquid. The determination of the right vaporization method leads to the careful selection and specification of the supporting instruments – gas / liquid flow controllers / meters, vaporization nozzles and temperature controllers. Not an easy process but a process in which HORIBA is a global leader.
HORIBA has vaporization solutions ranging from fractional grams/minute to >25g/min. As a solutions provider, we can not only recommend vaporization components like our VC and MV series but we can also provide a fully integrated system like our LSC / LU. By using our world-leading gas and liquid mass flow controllers and meters in conjunction with our vaporizers, users are assured accurate and repeatable vaporization of critical process chemistries.
Providing a long standing history of expertise in metrology developments and technological innovations, HORIBA is proud to be a respected leader in the Semiconductor and other industries.
