1. A chemical liquid injector for injecting a chemical liquid filled in a container comprising:
a first driving mechanism configured to make a first chemical liquid flow out of a first container filled with the first chemical liquid,
a second driving mechanism configured to make a second chemical liquid flow out of a second container filled with the second chemical liquid,
at least one data input interface which receives an input of data, and
an injection controller configured to control an operation of at least the first driving mechanism and the second driving mechanism,
wherein at least a multistage injection mode for performing a series of injection operation in a plurality of injection phases including a first phase and a second phase is set in the injection controller as one of at least one injection mode of the chemical liquid, and
the injection controller is configured to:
receive the input of a mixing rate of the first chemical liquid and the second chemical liquid through the data input interface for each of the plurality of injection phases in the multistage injection mode,
set injection conditions of the first chemical liquid and the second chemical liquid so that the first chemical liquid and the second chemical liquid are injected at a mixing rate received by the injection controller, and
control the operation of the first driving mechanism and the second driving mechanism according to injection conditions set by the injection controller, and
wherein the mixing rate received by the injection controller is in a range of 0% to 100%, and
the injection controller can set injection patterns including:
(a) an injection pattern when the mixing rate of the first chemical liquid and the second chemical liquid is set to other than 0% in both the first phase and the second phase,
(b) an injection pattern when the mixing rate of the second chemical liquid is set to 0% in the first phase, and the mixing rate of the first chemical liquid and the second chemical liquid is set to other than 0% in the second phase, and
(c) an injection pattern when the mixing rate of the first chemical liquid and the second chemical liquid is set to other than 0% in the first phase, and the mixing rate of the second chemical liquid is set to 0% in the second phase.
