  • Publication number: 20030089457
    Abstract: Apparatus for controlling a thermal conductivity profile of a pedestal in a semiconductor wafer processing system. One embodiment of the apparatus is a thermal shim that is positioned between a wafer retention device (e.g., electrostatic chuck) and a pedestal. The shim controls the thermal conductivity between the wafer retention device and the pedestal. In one embodiment, the thermal shim has a low thermally conductive region and a high thermally conductive region. In a further embodiment, the low thermally conductive region is a hole. By having a hole in the center of the shim, thus forming an annulus, an air gap is formed between the wafer retention device and the pedestal such that less heat will be transferred through the air gap as compared to the high thermally conductive region of the shim.

  • Publication number: 20030070758
    Abstract: A substrate to be processed in a high temperature processing chamber is preheated to avoid the problems associated with thermal shock when the substrate is dropped onto a heated susceptor. Preheating is effected by holding the substrate over a susceptor maintained at or near the processing temperature until the temperature of the substrate approaches the processing temperature. Thus, wafer warping and breakage are greatly reduced, and wafer throughput is improved because of time saved in maintaining the susceptor at constant temperature without cool down and reheat periods.

A ceramic made support member having a substantially cylindrical shape is provided in a process chamber. An upper end of the support member is airtightly connected to a back surface of a placement table by solid state bonding. A lower end of the support member is airtightly connected to a bottom of the process chamber via a lower cooling jacket and O-rings. A cooling jacket made of a disc-like aluminum block is provided in an atmosphere chamber formed inside the support member. The cooling jacket is mounted to the back surface of the placement table via a heat conductive sheet member.

  • Patent number: 6423178
    Abstract: A plasma processing apparatus that excites plasma in a container and processes an object in the plasma. This plasma processing apparatus includes: a gas supply system that supplies a process gas required for exciting the plasma; an exhaustion system that exhausts the process gas and evacuates the container; and a conductive stage on which the object to be processed is placed, the conductive stage being placed in the container. In this plasma processing apparatus, a DC voltage or high-frequency power is applied to the conductive stage; and a cooling passage for cooling the object to be processed is disposed in the stage, the cooling passage being made of a material having a high heat conductivity so as to transmit heat of the stage to the refrigerant, and a high electrical insulating strength so as not to transmit the DC voltage or high-frequency power applied to the stage to the refrigerant.

  • Patent number: 6416618
    Abstract: There is described a wafer processing apparatus intended to efficiently secure a wafer on an electrostatic chuck. A heater is disposed in a processing chamber for heating a wafer, and a dielectric plate for supporting the wafer is also disposed in the processing chamber. First and second electrodes are embedded in the dielectric plate, and first and second variable D.C. power supplies are disposed so as to supply voltages to the first and second electrodes, respectively. After the wafer has been placed on an electrostatic chuck, the wafer is pre-heated before being subjected to attraction force. After completion of the pre-heating phase, the first and second D.C. power supplies supply voltages to the first and second electrodes, thus securing the wafer on the dielectric plate.

  • Patent number: 6406545
    Abstract: A wafer processing apparatus includes a processing chamber, a chuck arranged in the processing chamber for supporting a wafer, and a pedestal which is spaced apart from the chuck. A first gas layer is provided between the chuck and the wafer and a second gas layer is provided in the space between the pedestal and the chuck. The pressure of the first gas layer is controlled to be in a pressure range in which a thermal conductivity of the first gas layer is substantially constant with respect to changes in pressure of the first gas layer and the pressure of the second gas layer is controlled so as to control an amount of heat transferred to/from the pedestal.
