摘要：
Provided is an inkjet printhead having an array of ink chambers formed on a planar support surface of a wafer substrate. Each ink chamber in the array has a nozzle, a thermal actuator for ejecting ink through the nozzle and a droplet stem anchor. The thermal actuator has two sections with higher resistance than the remainder of the thermal actuator. The droplet stem anchor is positioned between the two sections with higher resistance of the thermal actuator.
