摘要:
A low defect rate is provided in rapid thermal processing of delicate components with reduction of defects caused by inhomogeneities of temperature during a rapid thermal processing. In a suitable system a defect-guarded RTP method is carried out in such a manner that the density of the heating energy is adjusted in consecutive intervals of time, which may be as short as desired, to such automatically controlled limiting values or to such fixed values that in the reaction chamber the difference between the primary and secondary energy densities is almost continuously held at the minimum which is achievable throughout the thermal processing whereas the ramps have predetermined slopes.

The aim of the invention is to provide an economical and homogenous thermal treatment for substrate. To this end, the inventive device and method for thermally treating substrates, especially semiconductor wafers, comprise at least one heating device for heating at least one substrate by electromagnetic radiation. Said heating device comprises at least two arc lamps, the radiation characteristics for each arc lamp being controlled individually, and the electromagnetic radiation of the arc lamps contributing essentially to the power density of the electromagnetic radiation of the heating device.

A method is provide for measuring electromagnetic radiation radiated from a surface of an object that is irradiated by electromagnetic radiation given off by at least one radiation source. The radiation given off by the radiation source is determined by at least one first detector, and the radiation given off by the irradiated object is determined by at least one second detector that measures the radiation. The radiation from the at least one radiation source is actively modulated with at least one characteristic pyrometer. The radiation determined by the second detector is corrected with the radiation determined by the first detector to compensate for the radiation of the radiation source reflected from the object.

A boat drive has a permanent magnet-excited, electronically commutated synchronous motor with a stator and a rotor. The number of poles of the stator and the number of poles of the rotor are different. The magnetic field created between the poles of the stator and the poles of the rotor is an essentially radial field with respect to the shaft of the rotor. The poles of the rotor have a greater distance from the shaft of said rotor than the poles of the stator.

A transportable outboard drive for a boat has a head, a pylon, a shaft connecting the head and the pylon, an electric motor and a cable running inside the shaft. The shaft has at least two shaft sections and wherein the head, shaft and pylon can be arranged in a working configuration or in a transport configuration. In the working configuration, the head, the shaft and the pylon are rigidly connected to each other. In the working configuration and the transport configuration, the cable and shaft are differently positioned with respect to each other, whereas, in its transport configuration, the shaft sections are separated from each other.
