摘要： An inkjet print head comprises an array of print head heater circuits. Each circuit has a heater element (12) and a drive transistor (14) in series between power lines (20,22), and with a node (23) at the junction therebetween. A first capacitive element (50) is coupled between a first control signal (52) and the node (23) and a second capacitive element (54) is coupled between a second control signal (56), which is complementary to the first control signal (52), and the node (23). The two capacitive elements can be used to capacitively couple opposite step voltage changes into the circuit. These capacitive coupling effects can be used to alter the switching characteristics so as to reduce simultaneous high voltages on the gate and drain of the drive transistor.

摘要： An inkjet print head comprising an array of print head heater circuits, each associated with a respective print head nozzle. Each heater circuit comprises a heater arrangement (12) and a drive transistor (10) for driving current through the heater arrangement (12) connected in series between power lines (V s , GND). The heater arrangement (12) comprises a plurality of diode elements (16) in series. The diode elements have an inherent resistance, to provide the required heating, but the voltage drops across the diode elements enable the voltage across the transistor when in the off condition to be reduced. This enables a reduction in size of the transistor and/or enables a higher supply voltage to be used.

One method includes providing a semiconductor substrate wafer having a thickness greater than about 500 microns and having a device side and a back side opposite the device side. The back side of the wafer is mechanically ground to provide a wafer having a thickness ranging from about 100 up to about 500 microns. Dry etching is conducted on the wafer from a device side thereof to form a plurality of reentrant fluid feed slots in the wafer from the device side to the back side of the wafer.
