    摘要: A method of testing a test wafer includes shielding test centers on a test wafer using shielding tabs during the deposition of a layer. The test wafer has the same size and shape of product wafers. The shielding tabs are then removed from the test wafer. A plurality of predetermined points which are separated from each test center by a critical interval are checked, and whether each point is covered by the layer is determined through an interferometer or a microprobe. The test wafer is processed after adjustments to or maintenance on equipment, or after a fixed number of product wafers have been processed.

    摘要: In some embodiments, the present disclosure relates to a plasma processing system comprising a magnetron configured to provide a symmetric magnetic track through a combination of vibrational and rotational motion. The disclosed magnetron comprises a magnetic element configured to generate a magnetic field. The magnetic element is attached to an elastic element connected between the magnetic element and a rotational shaft configured to rotate magnetic element about a center of the sputtering target. The elastic element is configured to vary its length during rotation of the magnetic element to change the radial distance between the rotational shaft and the magnetic element. The resulting magnetic track enables concurrent motion of the magnetic element in both an angular direction and a radial direction. Such motion enables a symmetric magnetic track that provides good wafer uniformity and a short deposition time.

    摘要: A workpiece transfer system has a plurality of joints having a bearing and a primary and secondary transformer coil, wherein power provided to the primary transformer coil and secondary transformer coil of each joint produces mutual inductance between the primary and secondary transformer coil of the respective joint. A first pair of arms are rotatably coupled to a blade by a first pair of the joints, wherein the primary transformer coil of each of the first pair of joints is operably coupled to the first pair of arms, and the secondary transformer coil of each of the first pair of joints is operably coupled to the blade and an electrode beneath a dielectric workpiece retaining surface of the blade. The electrode is contactlessly energized through the transformer coils of the joint and the blade can chuck and de-chuck a workpiece by reversing current directions and by voltage adjustment.

    摘要: An electrostatic chuck for clamping a warped workpiece has a clamping surface comprising a dielectric layer. The dielectric layer has a field and one or more zones formed of differing dielectric materials. One or more electrodes are coupled to a power supply, and a controller controls a clamping voltage supplied to the one or more electrodes via the power supply. An electrostatic attraction force associated with each of the field and one or more zones of the dielectric layer of the electrostatic chuck is induced, wherein the electrostatic attraction force varies based on the dielectric material of each of the field and one or more zones. The electrostatic attraction force is greater in the one or more zones than in the field, therein attracting warped regions of the workpiece to the clamping surface and clamping the warped workpiece to the clamping surface across a surface of the warped workpiece.

    摘要: The present disclosure is directed to a physical vapor deposition system configured to heat a semiconductor substrate or wafer. In some embodiments the disclosed physical vapor deposition system comprises at least one heat source having one or more lamp modules for heating of the substrate. The lamp modules may be separated from the substrate by a shielding device. In some embodiments, the shielding device comprises a one-piece device or a two piece device. The disclosed physical vapor deposition system can heat the semiconductor substrate, reflowing a metal film deposited thereon without the necessity for separate chambers, thereby decreasing process time, requiring less thermal budget, and decreasing substrate damage.
