Abstract: A method of conserving a facility delivered to a machine during the machine's idle mode is herein described. In one embodiment, the method is directed to a method for conserving coolant water delivery to a semiconductor wafer grinding machine. The system monitors the status of the grinder to determine whether the grinder is active or idle.

In one embodiment, the flow is simply reduced while, in another embodiment, the flow is terminated. A delay circuit in the system may delay the reduction of the flow rate until some point after entering idle mode. Periodically throughout the idle mode, the system increases the flow of coolant water to the grinder to ensure the temperature of all grinder components remains consistent. The duty cycle of the coolant flow may be adjusted to optimize water conservation and machine readiness.
