A inkjet printhead integrated circuit that has a wafer substrate with a fluid ejection surface, and an array of drop ejectors for ejecting drops of printing fluid onto a media substrate, the array being formed on the fluid ejection surface of the wafer substrate. Each drop ejector has a nozzle through which the drops are ejected, an actuator for ejecting drops through the nozzle and, a drive transistor for energizing the actuator with a drive pulse. The area of the drive transistor projected onto the fluid ejection surface is less than 37 times the area of the nozzle. |
