Abstract
In one of the preferred embodiments, an inkjet printhead includes a nozzle member formed of a polymer material that has been laser-ablated to form inkjet orifices, ink channels, and vaporization chambers in the unitary nozzle member. The nozzle member is then mounted to a substrate containing heating elements associated with each orifice. In a preferred method, the orifices, ink channels, and vaporization chambers are formed using an Excimer laser.
