A printing surface includes a substrate having latching electrodes on a first surface, a spacer layer on the first surface of the substrate, the spacer layer patterned to form wells such that the latching electrodes reside in the wells, a deformable membrane, the membrane having conductive regions, on the spacer layer to enclose the wells, each enclosed well and its associated region of the membrane forming a pixel membrane, and actuation circuitry to actuate the electrodes to cause selected ones of the pixel membranes to remain in a deflected state when the pixel membranes receive an impulse to return to an undeflected state.

A printing plate has a substrate and a heat decomposable polymer layer arranged adjacent to the substrate, the decomposable polymer having defined regions within the polymer layer to form a printing pattern. The printing plate may be used in a printing system. The printing plate is formed in a process by providing a substrate, coating the substrate with a heat decomposable polymer to form a plate, and forming a printing pattern in the heat decomposable polymer by selectively decomposing regions of the heat decomposable polymer.

Fluidic conduits, which can be used in microarraying systems, dip pen nanolithography systems, fluidic circuits, and microfluidic systems, are disclosed that use channel spring probes that include at least one capillary channel. Formed from spring beams (e.g., stressy metal beams) that curve away from the substrate when released, channels can either be integrated into the spring beams or formed on the spring beams. Capillary forces produced by the narrow channels allow liquid to be gathered, held, and dispensed by the channel spring probes. Because the channel spring beams can be produced using conventional semiconductor processes, significant design flexibility and cost efficiencies can be achieved.

A package has a pad chip having contact pads, a spring chip having micro-springs in contact with the contact pads to form interconnects, the area in which the micro-springs contact the contact pads forming an interconnect area, a chemical activator in the interconnect area, and an adhesive responsive to the chemical activator in the interconnect area. A package has a pad chip having contact pads, a spring chip having micro-springs in contact with the contact pads to form interconnects, a chemical activator on one of either the pad chip or the spring chip, and an adhesive responsive to the chemical activator on the other of either the pad chip or the spring chip. A method includes providing a pad chip having contact pads, providing a spring chip having micro-springs, applying a chemical activator to one of either the pad chip or the spring chip, applying an adhesive responsive to the chemical activator on the other of the pad chip or the spring chip, aligning the pad chip to the spring chip such that the micro-springs will contact the contact pads, and pressing the pad chip and the spring chip together such that the chemical activator at least partially cures the adhesive.

摘要:
Scanning probe systems, which include scanning probe microscopes (SPMs) are disclosed that include cantilevered spring (e.g., stressy metal) probes and actuation/position sensing electrodes formed on a substrate. The actuation electrodes are used to position the spring probe relative to the substrate using electrostatic, magnetic, acoustic, or piezoelectric arrangements. An actuation signal source is switched between full on and off states to facilitate “ON/OFF” probe actuation in which the spring probe is either fully retracted against the substrate or deployed for scan operations. The position sensing electrodes are used to sense the deflected position of the spring probe relative to the substrate using resistive, magnetic, or piezoresistive arrangements. Spring probe arrays are disclosed that include multiple spring probes arranged on a single substrate. Each spring probe of the array includes a separate actuation electrode that is controlled using “ON/OFF” or tapping probe actuation, and may include a separate position sensing electrode.

A method of assembling a package includes aligning a pad chip with a spring chip to form at least one interconnect in an interconnect area, adhering the pad chip to the spring chip so that there is a gap between the pad chip and the spring chip, dispensing underfill material into the gap to seal the interconnect area from an environment external to the package, and curing the underfill material to form a solid mold.
