INK JET PRINTER WITH EXTEND NOZZLE PLATE AND METHOD

摘要

The invention provides a micro-fluid ejection head (40) for a micro-fluid ejection device and a method for making a micro-fluid ejection head. The micro-fluid ejection head (40) includes a semiconductor substrate (44) containing fluid ejection devices (49) electrically connected to contact pads (58) on a surface thereof. A TAB circuit (62) including lead beams (60) is electrically connected to the contact pads (58) on the semiconductor substrate surface. A nozzle plate structure (46) is provided and installed relative to the TAB circuit (60) so as to substantially cover the lead beams (60) and contact pads (58) in order to protect the lead beams and contact pads from exposure to fluid ejected by the micro-fluid ejection device. The micro-fluid ejection head (40) is effective to reduce contact between electrical components and the fluid without the use of a separate encapsulant material.
