    Abstract: The invention is directed to aperture mask deposition techniques for use in creating integrated circuits or integrated circuit elements. The techniques involve sequentially depositing material through a number of aperture masks formed with patterns that define layers or portions of various layers of a circuit, wherein the aperture masks have alignment edges that contact at least three contact points of an alignment fixture. In this manner, circuits can be created using aperture mask deposition techniques, without requiring any etching or photolithography, which is particularly useful when organic semiconductors are involved. The techniques can be useful in creating circuit elements for electronic displays, low-cost integrated circuits such as radio frequency identification (RFID) circuits, and other circuits.

    Abstract: Microneedle arrays, methods of manufacturing microneedles and methods of using microneedle anays. The microneedles (20) in the microneedle arrays may be in the form of tapered structures that include at least one channel (22) formed in the outside surface of each microneedle. The microneedles may have bases (26) that are elongated in one direction. The channels in microneedles with elongated bases may extend from on of the ends of the elongated bases towards the tips of the microneedles. The channels formed along the sides of the microneedles may optionally be terminated short of the tips of the microneedles The microneedle arrays may also include conduit structures formed on the surface of the substrate on which the microneedle array is located. The channels in the microneedles may be in fluid communication with the conduit structures. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue.
