Field: Textile and paper machines (Mechanical engineering)
Classification: CPC G  B | IPC B  G

Claim 0:
1. An apparatus comprising:
a performance monitor configured to determine a performance characteristic of a plurality of dispensers receiving fluid from a reservoir, wherein each of the plurality of dispensers has an actuator that, when actuated, causes the each of the dispensers to generate a droplet of the fluid on a semiconductor substrate in a nanoimprint lithography system; and
a driver configured to generate a drive command to the actuator to adjust a physical attribute of the droplet based on the performance characteristic to satisfy a performance criteria related to uniformity of a residual layer thickness,
wherein the drive command is based on feedback information related to variation of the physical attribute,
wherein the variation includes a variance of values representing the physical attribute,
wherein the driver comprises:
an adjustment storage configured to store an adjustment schedule for adjusting the drive command by translating the performance characteristic into values corresponding to the drive command; and
a command generator configured to generate the drive command based on the performance characteristic and the adjustment schedule,

wherein the performance monitor comprises:
a memory configured to store a usage of the plurality of dispensers; and
a rate calculator configured to calculate the utilization rate of a subset of the plurality of dispensers based on the usage, and

wherein the driver generates the drive command corresponding to the utilization rate calculated by the rate calculator based on a correspondence between the utilization rate and the values corresponding to the drive command.
