Method of fabricating resistor and proximate drive transistor for a printhead
An inkjet nozzle unit includes a first wafer having formed therein active drive circuitry and an ink ejection nozzle; a second wafer having an ink channel formed therein; an ink chamber complementarily defined between the first and second wafers; and two solenoid coils forming a paddle layer provided in the ink chamber, the paddle layer in signal communication with the active drive circuitry.
1. An inkjet nozzle unit comprising:
a first wafer having formed therein active drive circuitry and an ink ejection nozzle;
a second wafer having an ink channel formed therein;
an ink chamber complementarily defined between the first and second wafers; and
two solenoid coils forming a paddle layer provided in the ink chamber, the paddle layer in signal communication with the active drive circuitry.
2. The inkjet nozzle of claim 1 , wherein the first wafer includes a silicon wafer having provided thereon an epitaxial boron doped layer and an epitaxial silicon layer, the silicon wafer having drive transistors and distribution circuitry constructed thereon to provide a CMOS logic.
3. The inkjet nozzle of claim 1 , wherein the paddle layer is finished with a planarized glass layer.
