Abstract
An ink jet method for forming patterned layers on substrates permits a predetermined number of substrates to have respective patterned layers formed thereon. The inkjet method, however, further prevents clogging of the ink jet system when not in use to coat/layer substrates. A further step is provided, after all the desired substrates have been patterned, that making the liquid level of the ink in the nozzle changed within each predetermined time interval during/over the course of a predetermined amount of time. By changing the liquid level of the ink in the nozzle in a given period, each nozzle is able to remain unclogged (i.e., the ink in a nozzle does not have sufficient time to dry/harden prior to being jetted).
