Abstract
A bubble-jet type ink-jet printhead is provided. The printhead has an ink channel having a simple structure, thereby significantly suppressing clogging of nozzles by particles or solidified ink. The printhead is easy to design and manufacture due to its simple structure, thereby significantly reducing the manufacturing cost. In particular, its simple structure permits flexibility in selecting a wide range of alternative designs and thus patterns in which the nozzles are arranged. Furthermore, the printhead can be manufactured by a fabrication process for a typical semiconductor device, thereby facilitating high volume production.
