Ultra high-speed mass flow controller with response time of 200msec.

MC-7000 Series

Achieves high-speed flow control of 200msec (typical) by using a thermal sensor. By using the Lintec’s unique non-contact, thermal flow rate sensor and piezo control valve, it’s possible to control the flow of corrosive gases with ultra-high speed.

This product offers ±1.0% S.P. high accuracy flow rate control, and has DeviceNet or EtherCAT digital communication interface available for selection.

Example of Use

High-speed etching process

In semiconductor manufacturing process, there is a need to improve the throughput in parallel with miniaturization. Even for mass flow controllers that control the flow rate of reactant gases, there is an increasing demand for shorter flow rate control start (rise) times. The ultra high-speed mass flow controller [MC-7000] is a non-contact thermal flow sensor that does not contact the flow sensor and the flow measuring gas and achieving an ultra-high-speed response of 200 msec. Since it is a non-contact type, high-speed flow rate control is possible for measuring the flow rate of corrosive gases.
