20090032935 | Semiconductor device - Embodiments of a semiconductor device are disclosed. | 02-05-2009 |
20090053898 | Formation of a slot in a silicon substrate - A slot is formed that reaches through a first side of a silicon substrate to a second side of the silicon substrate. A trench is laser patterned. The trench has a mouth at the first side of the silicon substrate. The trench does not reach the second side of the silicon substrate. The trench is dry etched until a depth of at least a portion of the trench is extended approximately to the second side of the silicon substrate ( | 02-26-2009 |
20090096845 | PRINT HEAD DIE SLOT RIBS - Methods and an apparatus are disclosed, wherein a print head die includes a slot and ribs across the slot. The ribs are recessed from one or both sides of the die. | 04-16-2009 |
20100271445 | Fluid Ejection Cartridge And Method - A fluid ejection cartridge includes a body, having fluid passageways at a first spacing, a die, having fluid passage-ways at a second closer spacing, and an interposer, bonded to the body at a first surface and plasma bonded to the die at a second surface. The interposer includes fluid passageways between the first and second surfaces, which are substantially aligned with the respective passageways of the body and the die. | 10-28-2010 |
20110018938 | PRINTING DEVICE - A printing device ( | 01-27-2011 |
20110069120 | PRINT HEAD SLOT RIBS - A print head die ( | 03-24-2011 |
20120139997 | PROTECTIVE COATING FOR PRINT HEAD FEED SLOTS - A method of method of making a corrosion resistant print head die comprises creating a self-ionized plasma (SIP) of a coating material; establishing a bias on a print head die comprising a plurality of feed slots ( | 06-07-2012 |
20130027471 | Manufacture of a Print Head - Manufacturing method for an inkjet print head, comprising forming a nozzle layer onto a substrate, depositing an LSE (low surface energy) coating onto the nozzle layer, depositing a sacrificial film onto the LSE coating, post processing the substrate, and removing the sacrificial film from the LSE coating, the LSE coating having a water contact angle of at least 50° after removal of the sacrificial film. | 01-31-2013 |
20130033548 | Print Head - Thermal inkjet print head, comprising a fluid feed channel for delivering fluid, fluid chambers arranged near the fluid feed channel for receiving fluid from the fluid feed channel, resistors for actuating the fluid in the chambers, arranged in a staggered pattern with respect to a fluid feed channel wall, and a cantilever extending over the fluid feed channel wall, having a staggered edge that follows the staggered pattern of the resistors. | 02-07-2013 |
20130256260 | METHOD OF FORMING SUBSTRATE FOR FLUID EJECTION DEVICE - A method of forming a substrate for a fluid ejection device includes forming an opening in the substrate from a second side of the substrate toward a first side of the substrate, further forming the opening in the substrate to the first side of the substrate, anisotropically wet etching the substrate, including increasing the opening at the second side of the substrate and forming the opening with converging sidewalls from the second side to the first side, and after anisotropically wet etching the substrate, isotropically etching the substrate. | 10-03-2013 |
