Definitions

  • ABSTRACT The invention relates to a susceptor for heating bodies by means of high frequency energy.
  • the lower side of the susceptor comprises a profile which consists of longitudinal grooves present near the side surfaces. By means of said grooves on the lower side, a homogeneous temperature distribution is obtained on the upper,side transversely over the susceptor.
  • the invention relates to a method of treating a body, preferably a semiconductor body, which is present at a first surface of an elongate susceptor and which is heated by means of a high frequency energy source via the susceptor, said susceptor comprising a profile on a second surface opposite to the first surface.
  • the invention also relates to articles manufactured by means of the method, to a susceptor for use of the method, and to a device for carrying out the method.
  • the second surface of the susceptor comprises a profile having a substantially constant cross section viewed in the longitudinal direction of the susceptor, while in the centre of the said surfaces the susceptor is thinner than at the side surfaces.
  • the invention is based on the recognition of the fact that a more homogeneous temperature distribution can be obtained with a quite different profile.
  • the method mentioned in the preamble is characterized in that asusceptor is used the profile of which consists of grooves which extend tion transverse to the longitudinal direction over the 7 first surface of the susceptor.
  • a susceptor is preferably used, the profile of which consists of one groove along each of the side surfaces.
  • Such a method is preferably carried out in a device which comprises at least one susceptor according to the invention.
  • the invention also relates to a semiconductor device which is manufactured from a semiconductor body treated while using the last-mentioned method.
  • semiconductor devices which otherwise are manufactured in any conventional manner, have readily reproducible properties and are obtained in comparatively large yields.
  • FIG. 1 shows temperature distributions corresponding to places on susceptors which are shown in FIG. 2 to 4
  • FIG. 2 is a cross-sectional view of an unprofiled susceptor transverse to the longitudinal direction
  • FIG. 3 and 4 are cross-sectional views transverse to the longitudinal direction of susceptors according to the invention.
  • the temperatures shown in FIG. 1 are the temperatures which have been measured on semiconductor bodies 1 on the first surface 2, 3 or 4 of the susceptors 5, 6 or 7 in the places denoted by the crosses (see FIG. 2, 3 and 4).
  • the susceptors are 400 mm long, 116 mm wide and 13 mm thick.
  • the susceptors are of graphite.
  • the susceptor shown in FIG. 3 comprises, at 7 mm from the side surfaces 9, grooves 8 which are 4 mm deep and 6 mm wide.
  • the susceptor 7 shown in FIG. 4 has, at 7 mm from the side surfaces 10, grooves 11 which are 5 mm deep and 6 mm wide.
  • the temperature distribution over a 92 mm wide region, has decreased from 27-30+ C to approximately 16 C in the case of the-profiled susceptor 6 shown in FIG. 3 and to 14 C in the case of the susceptor shown in FIG. 4, and the distribution of the susceptor shown in FIG. 2, over a range of 78 mm wide, from 20 C to approximately 9 C in the susceptor shown in FIG. 3 and approximately 5 C in the susceptor shown in FIG. 4.
  • the above-mentioned dimensions are given only by way of example.
  • the grooves may be wider, for example.
  • the optimum dimensions of the grooves are also influenced by the wayof cooling the device in which the susceptors are used and by the major dimensions of the susceptor.
  • a susceptor for uniformly heating in a high frequency field a substance in contact therewith compris- 1 ing a body having two opposed major surfaces, one major surface having two opposed edges and two grooves, each groove being substantially coextensive with and respectively spaced adjacent to said opposed edges, whereby when said body isin a high frequency field, said grooves effectively increase the heat generated by said field in said. body in the region of said grooves resulting in a more substantially homogeneous heat distribution at the other major surface and in substance in contact therewith.
  • a susceptor as set forth in'claim l wherein said body is rectangularly shaped and said grooves are parallel with said opposed edges and respectively spaced from said edges by a distance less than the distance between said opposed'major surfaces.
  • a susceptor as set forth in claim 1 adapted to be placed in contact with a semiconductive body for homogeneous heating of said semiconductive body.
