Inkjet nozzle array with individual feed channel for each nozzle

USPTO Application #: 20070296765
Title: Inkjet nozzle array with individual feed channel for each nozzle
Abstract: An inkjet drop ejection apparatus comprising: an array of ink ejection nozzles, each nozzle having a chamber with an actuator for ejecting drops of ink through the nozzle, and an ink inlet in fluid communication with the ejection nozzle; and, a plurality elongate ink feed channels connected to each of the ink inlets respectively. By etching long ink feed channels for each nozzle eliminates fluidic cross talk between adjacent nozzles. An ink feed channel that supplies several nozzles needs to incorporate special features such as pinch points to deal with fluidic cross talk. The ink can be supplied from the ‘back’ surface of the wafer, thereby removing the need for ink feed channels beside the chambers. This provides more room for the power and print data to be connected to each nozzle along the front surface of the wafer. (end of abstract)
