- the inner wall of FIG. 5 is a schematic diagram showing in detail the form of the inner wall of the opening when the opening is formed for each support frame.
- the boundary indicated by the dashed line indicates the inner wall of the designed opening 4a
- the boundary indicated by the broken line indicates the opening formed when the support frames are joined and then etched.
- the openings are formed before the respective support frames are joined, thereby shortening the time required for etching. That is, by forming an opening in accordance with the thickness of each support frame before joining, the etching time can be shortened and the progress of side etching can be suppressed. Therefore, the error between the inner wall of the opening 4a to be formed and the inner wall of the designed opening is small, and there is an advantage that the dimensional control of the opening 4a can be easily performed.
- diffusion bonding between the support frames and brazing of the ceramic material 21 are performed simultaneously. This is because the temperature required for diffusion bonding in the present embodiment is about 800 ° C. or higher, and the vigorous temperature conditions also satisfy the brazing temperature conditions. By performing diffusion bonding and brazing simultaneously Thus, the number of steps required to manufacture the conductive contact holder 1 can be reduced, and the conductive contact holder 1 can be manufactured at low cost.

- the linear expansion coefficient and the thickness of these support frames are as follows. By adjusting only the position, the occurrence of displacement between the object 8 and the object 8 under high temperature conditions is suppressed. As described above, even when the configuration in which the support 24 is inserted as a reinforcing member into the holder substrate 25 is adopted, by adjusting the linear expansion coefficient of the entire support 24 so as to conform to the contacted object 8, It is possible to realize a conductive contact unit that can be used under high temperature conditions.

- a material that satisfies conditions such as workability.
- the slight difference in the linear expansion coefficient between the holder hole forming portion 31 and the contacted body 8 is particularly attributable to the fact that the contacted body 8 has a structure including a large number of semiconductor elements like a semiconductor wafer, and the conductive contact holder is
- the positional deviation caused by each of the holder hole forming portions 31 is within the allowable range, the positional deviations generated in the multiple holder hole forming portions 31 are superimposed, and thus the position of the contacted member 8 is reduced.
- the position is displaced to the extent that inspection is impossible.
- the linear expansion coefficient of the support 36 is adjusted. Is adopted. That is, in this modification, the linear expansion coefficient of the holder hole forming portion 31 is higher than the value of the contacted body 8, and in this case, the linear expansion coefficient and the thickness of the support frame such as the low thermal expansion support frame 32 are determined. By adjusting, the linear expansion coefficient of the support 36 is set to a value lower than the value of the contact object 8.
- the materials constituting the low thermal expansion support frames 32 and 35 and the high thermal expansion support frames 33 and 34 and the thickness of each material By adjusting the values of the linear expansion coefficients of the support body 36 and the holder hole forming section 31 as a whole, is there.
- the linear expansion coefficient of the support 36 is adjusted according to the linear expansion coefficient of the holder hole forming portion 31.
- the holder is adjusted according to the linear expansion coefficient of the support 36.
- the linear expansion coefficient of the hole forming part 31 may be adjusted.
