  • Patent number: 8150243
    Abstract: A heating process apparatus includes a process chamber, a heat-processed object support member provided in the process chamber for heating a substrate disposed thereon, a cap for covering the substrate disposed on the heat-processed object support member, a heater for heating the heat-processed object support member, a temperature measuring unit for measuring the temperature of the heat-processed object support member, and a controller for controlling the heater. A first measuring unit measures a temperature of the cap, and the controller controls the heater so as to set the cap temperature to a predetermined temperature. A second measuring unit measures a temperature of the heat-processed object support member, and the controller turns off the heater when the temperature of the heat-processed object support member exceeds an over-heat critical temperature.

  • Patent number: 7807553
    Abstract: A substrate heating apparatus having a heating unit for heating a substrate placed in a process chamber which can be evacuated includes a suscepter which is installed between the heating unit and a substrate, and on which the substrate is mounted, and a heat receiving member which is installed to oppose the suscepter with the substrate being sandwiched between them, and receives heat from the heating unit via the suscepter. A ventilating portion which allows a space formed between the heat receiving member and substrate to communicate with a space in the process chamber is formed.

  • Publication number: 20100006560
    Abstract: In a substrate heating apparatus including a vacuum vessel with an interior separated by a wall body into a first space and a second space, the first space being evacuated to a vacuum by a first exhaust means and accommodating a substrate to be heated, and the second space being evacuated to a vacuum by a second exhaust means and including a heating means for heating the substrate accommodated in the substrate, the time required to evacuate the first space to a vacuum by the first exhaust means is shortened, thus improving the throughput. The wall body has a non-coating surface, which is not coated, on part of a wall body surface which faces the second space. A coating is formed on the remaining portion of the wall body surface.

  • Patent number: 5304405
    Abstract: A thin film deposition apparatus has at least two vacuum chambers, one of which is an etching vacuum chamber for cleaning wafer surfaces. The etching vacuum chamber includes a first gas introduction system for introducing an etching gas, and a second gas introduction system for introducing a reactive gas for use in the cleaning whereby silicon deposited films will be removed. A thin film deposition method which may be carried out by the apparatus includes a cleaning process performed in advance of thin film deposition process for depositing a thin film on the wafer surfaces. In the cleaning process, the wafer surfaces are etched with the etching gas, the wafers are thereafter taken out of the chamber, a simulation wafer for particle checking is transferred into the chamber, and the degree to which particles have been generated is checked with the simulation wafer. When required, the reactive gas is introduced thereafter to gasify the deposited films and the particles.
