摘要： The invention provides a method for reducing ink corrosion of exposed metal layers on a chip surface of a semiconductor chip for an ink jet printhead. The method includes depositing a protective layer in a plasma process to the chip surface, the protective layer being deposited adjacent ink ejectors so that the protective layer substantially circumscribes an ink via in the chip. A thick film layer is applied to the protective layer and chip, whereby the protective layer and thick film layer are sufficient to promote increased adhesion between the thick film layer and a nozzle plate attached to the thick film layer thereby substantially reducing a tendency for the nozzle plate and thick film layer to delaminate from one another during printhead manufacture or use and interrupting contact between ink and the exposed metal layers on the chip surface.

摘要翻译：本发明提供一种用于降低喷墨打印头半导体芯片的芯片表面上暴露的金属层的油墨腐蚀的方法。该方法包括将等离子体处理中的保护层沉积到芯片表面，保护层邻近墨水喷射器沉积，使得保护层基本上限制芯片中的墨通道。将厚膜层施加到保护层和芯片上，由此保护层和厚膜层足以促进厚膜层和附着在厚膜层上的喷嘴板之间的附着力增加，从而大大降低了喷嘴的趋势板和厚膜层在打印头制造或使用期间彼此分层，并且中断墨和芯片表面上暴露的金属层之间的接触。

摘要： An inkjet printhead heater chip has an ink via asymmetrically arranged in a reciprocating direction of inkjet printhead movement. The ink via has two sides and a longitudinal extent substantially parallel to a print medium advance direction. A column of fluid firing elements exists exclusively along a single side of the two sides. The heater chip and ink via each have a centroid and neither resides coincidentally with one another. Preferably, the heater chip centroid resides externally to a boundary of the ink via. In other aspects, the column of fluid firing elements can be a sole column or plural and may be centered in the reciprocating direction. The ink via can be a sole via or plural. The heater chip can be rectangular and the ink vias can be closer to either the long or short ends thereof. Inkjet printers for housing the printheads are also disclosed.

摘要： An n-bit serial shift register in an ink jet print head operates in a print mode or a test mode. When the shift register is operating in the print mode, n bits of print data are serially scanned into n number of bit registers and are then latched out to heater addressing logic circuitry in the print head to control a print operation. When the circuit is operating in the test mode, x bits of test point data from x number of test nodes in the print head are loaded in parallel into x number of the n number of bit registers, and are then serially scanned out to a test data output. In this manner, a single shift register may be used to scan in print data and scan out test data, thereby providing observability and controllability of the internal logic nodes of the print head while minimizing logic size and the number of input/output connections on the print head.

摘要： A micro-fluid ejection device, such as an inkjet printhead, includes a substrate, a heater chip on the substrate, a structure on the substrate for supplying ink to the heater chip and a nozzle plate on the heater chip. The heater chip has a plurality of electrically-activatable spaced apart heater elements that can be repetitively subjected to momentary electrical activation and deactivation so as to cause cyclical heating and cooling of ink in the heater chip resulting in repetitive ejection of drops of ink by the nozzle plate on the heater chip. The device also includes a thermal control system in the heater chip being self-managed by operation of a control loop defined by the thermal control system internally of the heater chip and substrate for sensing and limiting the variation of the temperature of the substrate during cyclical operation of the heater elements of the heater chip.

摘要： An apparatus provides identification information related to at least one ink jet print head in an ink jet printer. The apparatus includes a printer controller for providing a first identification data string comprising n number of bits, at least one of which has a first state, and no more than n−1 number of which have a second state different from the first state. Coupled to the printer controller is a first ink jet print head having a first serial input shift register. The first serial input shift register has at least n number of bit positions for receiving the n number of bits of the first identification data string. The first ink jet print head also includes at least n number of first latches, each of which is coupled to a corresponding one of the n number of bit positions of the first shift register. The n number of first latches are for latching the n number of bits of the first identification data string from the n number of bit positions of the first shift register. A first identification line, which is coupled to a predetermined one of the first latches, provides to the printer controller one of the n number of bits from the first identification data string that is latched into the predetermined one of the first latches. Based upon whether the bit provided on the first identification line has a first or second state, the printer controller determines whether the first print head is of a first type.

摘要： An inkjet printer includes a printhead for ejecting ink onto a print medium. The printhead includes electrical and mechanical structure for controlling the ejection of the ink. The printhead includes an ink ejector chip having at least one active device, such as a transistor and the like. A guard ring substantially surrounds select active devices included on the chip. The guard ring tends to prevent latch-up when the chip operates to energize the ink. The chip is manufactured using a substrate devoid of an overlying epitaxial layer which tends to reduce the cost of manufacturing the chip.
