- a predetermined temperature for example, 100 ° C. to 1 000 ° C.
- Heat treatment is performed (Patent Documents 1 to 6).
- the members in the processing container are required to have heat resistance against such heating and corrosion resistance that does not corrode even when exposed to the processing gas.
- a mounting table structure on which a semiconductor wafer is mounted generally has a heat resistance and corrosion resistance and needs to prevent metal contamination such as metal contamination.
- a ceramic material such as A1N is used. It has a mounting table formed by embedding a resistance heater as a heating element inside and integrally baking at a high temperature. Also, in another process, ceramic materials are fired in the same way to form the pillars. Then, the mounting table structure is manufactured by welding the mounting table side integrally fired and the support column by, for example, heat diffusion bonding. The integrally formed mounting table structure is provided upright on the bottom of the processing container. In some cases, quartz glass having heat and corrosion resistance is used instead of the ceramic material.

- the method of joining the conductive member 88 is the same as that of the second embodiment in that it uses spraying or the like. Also, as explained in FIG. 7, the thin plate 134 and the adhesive are used. 136 may be used for joining.
- FIG. 9 is a partial sectional view showing a fourth embodiment of such a mounting table structure according to the present invention. The same components as those shown in FIGS. 1 and 6 are given the same reference numerals, and the description thereof is omitted.
- the conductive member 88 is joined to the upper surface of the lid portion 78.
- the conductive member 88 is bonded to the upper surface after the upper surface of the lid portion 78 is polished flat like the lower surface of the lid portion 78 of the first embodiment.
- a protective layer is provided so as to cover the entire upper surface of the conductive member 88. 130 is formed.
- the joining method of the conductive member 88 is the same as that of the second embodiment in that it uses radiation or the like. Also, as described in FIG. 7, the thin plate 134 and the adhesive are used. 136 may be used for joining. Further, in the case of the fourth embodiment, a through hole 140 is formed in the lid portion 78, and a conductive line 90 is inserted into the through hole 140 and connected to the conductive member 88.
- the same operational effects as those of the second embodiment can be exhibited. Further, in the case of the fourth embodiment, the distance between the conductive member 88 and the wafer W or plasma placed above the conductive member 88 is the shortest. Can be increased.
- the force described by taking as an example the case where the heat generating member 38 is integrally incorporated in a disc-shaped quartz glass is not limited to this.
- a heating plate 40 formed by inserting a heating element (for example, a carbon wire heater) into a quartz glass tube bent like a meandering or spiral shape may be used.
- the force described with reference to the case of using plasma is used as an example of a simple heat treatment apparatus that does not use plasma.
- the high frequency power supply 17 for plasma, the matching circuit 15, and the noise circuit are used.
- the high frequency power supply 116 or the like is not necessary. Even in this case, the conductive member 88 having an electrostatic chuck function should be used.
- the force described by taking the semiconductor wafer as an example of the object to be processed is not limited to this, and it is needless to say that the present invention can be applied to an LCD substrate, a glass substrate, and the like.
