Abstract
A micro-miniature fluid ejecting device. The fluid ejecting device includes a semiconductor substrate having fluid ejectors formed on a surface of the substrate. A flexible circuit is fixedly attached to the semiconductor substrate. The flexible circuit has power contacts for providing power to the fluid ejectors. At least one drive circuit is connected to the fluid ejectors. The drive circuit is disposed on one of the semiconductor substrate and the flexible circuit. A fluid sequencer is connected to the drive circuit for selectively activating the fluid ejectors. The fluid sequencer is also disposed on one of the semiconductor substrate and the flexible circuit. The semiconductor substrate is attached to a housing. A fluid source is provided for supplying fluid to the semiconductor substrate for ejection by the fluid ejectors. The fluid ejecting device provides low cost construction for application specific miniature fluid jetting devices.
