    摘要: An electrostatic chuck (20) for holding a substrate (45) in a process chamber (80) having a voltage supply terminal (65) for charging the chuck (20). The chuck includes an electrostatic member (25) comprising at least one electrode (30), an electrically insulated holding surface (40) for holding a substrate (45) thereon, and an electrical contact surface (48) for providing charge to the electrode. A unidirectionally conducting coupler layer (70) electrically couples the contact surface (48) of the electrostatic member to the voltage supply terminal to conduct charge substantially only in a single direction from the terminal to the contact surface. Preferably, an electrical connector (50) having a junction surface (55) bonded to the contact surface (55) of the electrode, and a terminal surface (60) for electrically contacting the voltage supply terminal (65), is used to electrically couple the unidirectionally conducting coupler layer (70) to the voltage supply terminal (65).

    摘要: A multi-electrode electrostatic chuck (20) for holding a substrate (42) such as a silicon wafer during processing is described. The electrostatic chuck (20) comprises (i) a first electrode (22), (ii) a second electrode (24), and (iii) an insulator (26) having a lower portion (26a), a middle portion (26b) and an upper portion (26c). The lower portion (26a) of the insulator (26) is below the first electrode (22) and has a bottom surface (28) suitable for resting the chuck (20) on a support (44) in a process chamber (41). The middle portion (26b) of the insulator (26) lies between the first and second electrodes (22), (24). The upper portion (26c) of the insulator (26) is on the second electrode (24), and has a top surface (30) suitable for holding a substrate (42). The first and second electrodes (22, 24) can have a unipolar or bipolar configurations. In operation, the chuck (20) is placed on a support (44) in a process chamber (41) so that the bottom surface (28) of the chuck (20) rests on the support (44). A substrate (42) is placed on the top surface (30) of the chuck (20). When the first electrode (22) of the chuck (20) is electrically biased with respect to the support (44), a first electrostatic force holds the chuck (20) onto the support (44). When the second electrode (24) of the chuck (20) is electrically biased with respect to the substrate (42) placed on the chuck (20), a second electrostatic force holds the substrate (42) to the chuck (20).

    摘要: In accordance with the present invention, a polishing pad useful for polishing a semiconductor-comprising substrate is disclosed. The polishing pad is constructed to include conduits which pass through at least a portion of and preferably through the entire thickness of the polishing pad. The conduits, preferably tubulars, are constructed from a first material which is different from a second material used as a support matrix. The conduits are positioned within the support matrix such that the longitudinal centerline of the conduit forms an angle ranging from about 60.degree. to about 120.degree. with the working surface of the polishing pad. In the most preferred embodiment of the present invention, the conduits pass all the way through the thickness of the polishing pad and are sized to permit the flow of polishing slurry, reactive etchant material, heat transfer medium, and/or lubricant from a supply device through the conduits to the working surface of the polishing pad (at least a portion of which is in contact or near contact with the article to be polished).

    摘要: A transformer-coupled plasma source using toroidal cores forms a plasma with a high-density of ions along the center axis of the torus. In one embodiment, cores of a plasma generator are stacked in a vertical alignment to enhance the directionality of the plasma and generation efficiency. In another embodiment, cores are arranged in a lateral array into a plasma generating plate that can be scaled to accommodate substrates of various sizes, including very large substrates. The symmetry of the plasma attained allows simultaneous processing of two substrates, one on either side of the plasma generator.
