  • Patent number: 8168050
    Abstract: There is disclosed a wafer processing apparatus having optimized electrode patterns for its resistive heating element. The optimized electrode pattern is designed to compensate for the heat loss around contact areas, electrical connections, and through-holes, etc., by generating more heat near or around those areas, providing maximum temperature uniformity. In another embodiment of the optimized design of the invention, the resistance of heating element closely matches the impedance of the power supply for higher efficiency, especially when higher operating temperature or higher electrical power is required.

  • Publication number: 20120100119
    Abstract: Three types of trisiloxane surfactants having the basic formula: MDM? are described wherein the substituents on the differing M and M? groups, in conjunction with pendant polyalkylene oxide substituents on the D group render the surfactant resistant to hydrolysis under either basic or acidic conditions outside the pH range of 6.0 to 7.5. The compositions are useful in agricultural, household and cosmetic applications.

  • Patent number: 8164028
    Abstract: A heater has a smooth heating surface and a recess formed on a second surface opposite to the heating surface. The recess is formed between opposite side walls in a lengthwise direction of the heater. Formation of the recess improves the electrical resistance of the heater and the opposite side walls reinforce the heater and prevent deformation of the heater when it is subjected to high temperatures in a semiconductor wafer processing device. The heater has substantially the same width along its lengthwise direction. This improves the control of heat pattern design, because the terminal end portions do not have an expanded shape.
