    摘要: A method for producing a detection/test tape includes depositing a material onto a surface of at least one first substrate to form a plurality of element structures. Electrodes are deposited on a surface of each of the plurality of element structures, and the element structures are bonded to a second substrate, where the second substrate is conductive or has a conductive layer, and the second substrate is carried on a carrier plate. The at least one first substrate is removed from the element structures and second side electrodes are deposited on a second surface of each of the plurality of element structures. An insulative material is inserted around the element structures to electrically isolate the two substrates used to bond the element structures. A second side of the element structures is then bonded to another substrate, where the other substrate is conductive or has a conductive layer. Thereafter, the carrier plate carrying the second substrate is removed.

    摘要: A method of producing at least one piezoelectric element includes depositing a piezoelectric ceramic material onto a surface of a first substrate to form at least one piezoelectric element structure. Then an electrode is deposited on a surface of the at least one piezoelectric element structure. Next, the at least one piezoelectric element structure is bonded to a second substrate, the second substrate being conductive or having a conductive layer. The first substrate is then removed from the at least one piezoelectric element structure and a second side electrode is deposited on a second surface of the at least one piezoelectric element structure. A poling operation is performed to provide the at least one piezoelectric element structure with piezoelectric characteristics.In another embodiment, a material for a thick film element is deposited onto a surface of a first substrate to form a thick film element structure having a thickness of between greater than 10 μm to 100 μm. The at least one thick film element structure is bonded to a second substrate. Thereafter, the first substrate is removed from the at least one thick film element structure using a liftoff process which includes emitting, from a radiation source (such as a laser or other appropriate device), a beam through the first substrate to an attachment interface formed between the first substrate and the at least one thick film element structure at the surface of the first substrate. The first substrate is substantially transparent at the wavelength of the beam, and the beam generates sufficient energy at the interface to break the attachment.

    摘要: Inline methods for forming a photovoltaic cell electrode structure, wherein the photovoltaic cell includes a semiconductor substrate having a passivation layer thereon, includes providing a plurality of contact openings through the passivation layer to the semiconductor substrate, selectively plating a contact metal into the plurality of contact openings by printing electroless plating solution into the plurality of contact openings to deposit the contact metal, depositing a metal containing material on the deposited contact metal, and firing the deposited contact metal and the deposited metal containing material. The metal containing material may include a paste containing a silver or silver alloy along with a glass frit and is substantially free to completely free of lead. The methods may also use light activation of the passivation layer or use seed layers to assist in the plating.

    摘要: A multi-electrode piezoelectric diaphragm structure includes a diaphragm, piezoelectric material located on the diaphragm, which is defined as having a first area, and a second area. The first area of the piezoelectric is poled in a first direction, and the second area of the piezoelectric is poled in a second direction. The poled first direction is in a Z-axis of the piezoelectric and the poled second direction is in a Radial axis of the piezoelectric. A first electrode is positioned in the first area, on the first surface, of the piezoelectric. A second electrode is positioned in the second area, on the first surface, of the piezoelectric. A third electrode is located on a second surface of the piezoelectric. The application of voltages to the first, second and third electrodes generates electric fields in the piezoelectric material resulting in actuation of the piezoelectric material, or the application of pressure or strain to the diaphragm generates electric potentials at the first, second and third electrodes.
