    摘要: A print head assembly for an ink jet printer includes an ink flow path configured to allow passage of a phase-change ink. A pressure unit is fluidically coupled to the ink flow path to apply a pressure to the ink. The applied pressure is controlled by a control unit during a time that the ink in the ink flow path is undergoing a phase change. During the phase change, a portion of the ink in a first region of the ink flow path is in liquid phase and another portion of the ink in another region of the ink flow path is in solid phase. A constant or variable pressure can be applied at least to the liquid phase portion of the ink during a phase transition from a liquid phase to a solid phase or from a solid phase to a liquid phase.

    摘要: A metallization stack is provided for use as a contact structure in an integrated MEMS device. The metallization stack includes a titanium-tungsten adhesion and barrier layer formed with a platinum layer formed on top. The platinum feature is formed by sputter etching the platinum in argon, followed by a wet etch in aqua regia using an oxide hardmask. Alternatively, the titanium-tungsten and platinum layers are deposited sequentially and patterned by a single plasma etch process with a photoresist mask.

    摘要: A phase change ink printer may be operated so that multiple pressure pulses are applied to the ink in an ink flow path of the printer during a time that the ink is changing phase. During the phase change, a portion of the ink in the ink flow path is in liquid phase and another portion of the ink is in solid phase. The pressure pulses are applied at least to the liquid phase ink in the ink flow path. The phase change may involve a transition from solid to liquid phase, such as during a start-up operation, or may involve a transition from a liquid phase to a solid phase, such as during a power down operation. Application of pressure during either of these operations serves to reduce bubbles and voids in the phase change ink.

    摘要: A digital lithographic process first deposits a mask layer comprised of print patterned mask features. The print patterned mask features define gaps into which a target material may be deposited, preferably through a digital lithographic process. The target material is cured or hardened, if necessary, into target features. The mask layer is then selectively removed. The remaining target features may then be used as exposure or etch masks, physical structures such as fluid containment elements, etc. Fine feature widths, narrower the minimum width of the print patterned mask features, may be obtained while realizing the benefits of digital lithography in the manufacturing process.

    摘要: A print patterned mask is formed a digital lithographic process on the surface of a photoresist or similar material layer. The print patterned mask is then used as a development or etching mask, and the underlying layer overdeveloped or overetched to undercut the print patterned mask. The mask may be removed and the underlying structure used an etch mask or as a final structure. Fine feature widths, narrower the minimum width of the print patterned mask features, may be obtained while realizing the benefits of digital lithography in the manufacturing process.

    摘要: A digital lithography system including a droplet source (printhead) for selectively ejecting liquid droplets of a phase-change masking material, and an imaging system for capturing (generating) image data representing printed features formed by the ejected liquid droplets. The system also includes a digital control system that detects defects in the printed features, for example, by comparing the image data with stored image data. The digital control system then modifies the printed feature to correct the defect, for example, by moving the printhead over the defect and causing the printhead to eject droplets onto the defect's location. In one embodiment, a single-printhead secondary printer operates in conjunction with a multi-printhead main printer to correct defects.
