Publication number: 20110149000Abstract: A microdeposition system includes a stage, a printhead carriage, and a controller. The stage holds a substrate. The printhead carriage includes N printhead modules, where N is an integer greater than one. Each of the N printhead modules includes a printhead and an alignment mechanism. The printhead includes a plurality of nozzles that deposit droplets of fluid manufacturing material onto the substrate while relative movement between the substrate and the printhead is along a first axis. The alignment mechanism adjusts the printhead with respect to the printhead module. The controller controls the alignment mechanisms of the N printhead modules to set effective nozzle spacing for the pluralities of nozzles to a uniform value. The effective nozzle spacing is defined as spacing between adjacent ones of the plurality of nozzles as projected onto a second axis perpendicular to the first axis.Type: ApplicationFiled: December 22, 2010Publication date: June 23, 2011Applicant: ULVAC, INC.Inventors: David ALBERTALLI, James N. MIDDLETON, Roy M. Patterson

Patent number: 7901026Abstract: A drop analysis/drop check system allows a plurality of printheads to remain stationary during analysis to emulate operation of an actual piezoelectric microdeposition system. The system provides accurate tuning of individual nozzle ejectors and allows for substrate loading and alignment in parallel with drop analysis/drop check. The drop analysis/drop check system includes a motion controller directing movement of a stage, a printhead controller controlling a printhead to selectively eject drops of fluid material to be deposited on a substrate, and a camera supported by the stage for movement relative to the printheads. The camera receives a signal from the motion controller to initiate exposure of the camera and captures an image of the drops of fluid material ejected by the printheads. A light-emitting device includes a strobe controller that receives a signal from the camera to supply light to an area including the liquid drops during camera exposure.Type: GrantFiled: April 25, 2006Date of Patent: March 8, 2011Assignee: ULVAC, Inc.Inventors: David Albertalli, Robert G. Boehm, Jr., Oleg N. Gratchev, James N Middleton, Perry West

Patent number: 7815965Abstract: A microdeposition system microdeposits droplets of fluid material to define a feature pattern on a substrate. The feature pattern for the substrate is defined. A mask is created for the feature pattern that reduces a density of defects that occur due to a malfunctioning nozzle of the microdeposition head. The droplets of fluid material are microdeposited onto the substrate based on the mask to define sub-features of the feature pattern. One of the nozzles of the microdeposition head is assigned to each of the sub-features in the feature pattern. The nozzles may be assigned randomly or using other functions. The assigned nozzles in the mask are assigned to one of a plurality of passes of the microdeposition head.Type: GrantFiled: September 18, 2009Date of Patent: October 19, 2010Assignee: Ulvac, Inc.Inventors: Charles O. Edwards, David Albertalli

Patent number: 7757632Abstract: A microdeposition system and method includes a head with a plurality of nozzles. A controller generates nozzle firing commands that selectively fire the nozzles to create a desired feature pattern. Configuration memory stores voltage waveform parameters that define a voltage waveform for each of the nozzles. A digital to analog converter (DAC) sequencer communicates with the configuration memory and the controller and outputs a first voltage waveform for a first nozzle when a nozzle firing command for the first nozzle is received from the controller. A resistive ladder DAC receives the voltage waveforms from the DAC sequencer. An operational amplifier (opamp) communicates with the resistive ladder DAC and amplifies the voltage waveforms. The nozzles fire droplets when the voltage waveforms received from the opamp exceed a firing threshold of the nozzle.Type: GrantFiled: October 6, 2008Date of Patent: July 20, 2010Assignee: Ulvac, Inc.Inventors: Charles O. Edwards, David Albertalli, James Middleton, George Fellingham
