    摘要： A surface acoustic wave (SAW) device that is made with diamond, that has high efficiency, and that can be operated at high frequencies, particularly from 9.5 to 10.5 GHz. The SAW device comprises a diamond layer formed singly or formed on a substrate, a ZnO piezoelectric layer, interdigital transducers (IDTs), and a short-circuiting electrode as required. The SAW device has a structure in which the thickness of the ZnO layer, the wavelength of a harmonic of the SAW, and the line width of the IDTs fall in a specified range. With this structure, a large electromechanical coupling coefficient is obtained in a high-frequency range of 10 GHz band by utilizing the third or fifth harmonic of the SAW.

    摘要： A method for separating chips from a diamond wafer comprising a substrate, a chemically vapor-deposited diamond layer, and microelectronic elements, with the microelectronic elements protected from thermal damage and degradation caused by the thermally decomposed cuttings produced during the processing steps. (1) Front-side grooves 6 are formed on the chemically vapor-deposited diamond layer 2 by laser processing using a laser such as a YAG, CO2, or excimer laser each having a large output so that the grooves 6 can have a depth 1/100 to 1.5 times the thickness of the diamond layer. (2) The thermally decomposed cuttings produced during the laser processing are removed by using a plasma. (3) Back-side grooves 9 are formed on the substrate 1 by dicing such that the back-side grooves 9 are in alignment with the front-side grooves 6. (4) The diamond wafer 4 is divided into individual chips 10 by applying mechanical stresses.

    摘要： It is an object of the present invention to provide a wafer prober wafer holder that is highly rigid and increases the heat insulating effect, thereby improving positional accuracy, thermal uniformity, and chip temperature ramp-up and cooling rates, as well as a wafer prober device equipped therewith.A wafer holder of the present invention includes a chuck top that mounts a wafer, and a support member that supports the chuck top, wherein, a restricting member is provided that covers an interface between the chuck top and the support member. By covering the gap between the chuck top and the support member with the restricting member, the heat insulating effect can be increased by preventing the flow of outside air through the gap into the support member, and the cooling rate can be particularly improved if cooling to a temperature below room temperature.
