Background of the technology In recent years, with the trend toward larger semiconductor substrates, dust-free technology, and automation, the quartz container and quartz wafer basket holding the wafers slide in the horizontal furnaces that have been used in the past. , fine quartz particles are generated, which causes a decrease in the yield of sea urchin hubs. In addition, vertical furnaces have many advantages such as being easy to automate and occupying less space, so vertical furnaces are increasingly being used. Because the basket holder inserted into the heated container is supported at one end, if there is a large vibration from the outside, such as an earthquake, the basket holder may fall or tilt. There is a concern that the heating furnace and basket holder may be damaged, and conventional structures are required to be improved in terms of earthquake resistance.

(C1 Prior Art and Problems When forming an oxide film on a semiconductor substrate or doping and diffusing impurities into a semiconductor substrate, these semiconductor substrates are heated to a high temperature in an appropriate atmospheric gas. Usually, the heating furnace in this case is made at a temperature of about 1000°C. ゛Figure 1 shows a vertical heating furnace with a conventional structure, and in the figure, 1 is a tubular furnace core made of quartz. A basket holder 2 is inserted inside this, and wafer basket feet 3 are stacked in multiple stages inside this, and these are heated by a heating element 4 disposed around the furnace core.

In addition, the tubular heating tube has an atmospheric gas supply hole 5 and a discharge hole 6.
There is a sealed upper lid 7a and a lower lid 7b, and the basket holder is driven by a drive unit 9 by an operating cable 8. However, the heat-treated basket holder can be operated by removing the sealed upper lid. It is taken out to the outside by the cable 8.

In this case, since the basket holder is suspended only at the upper end of the basket holder with the operating cable 8, when the basket holder 2 vibrates due to external vibration, there is a gap between the diameter of the furnace core tube and the wafer basket. Since there is a slight amount of , there is a risk that the wafer basket may vibrate and come into contact with the furnace core tube, causing both to be destroyed, and there is a need for an improvement in this problem.

(fl Embodiments of the Invention In general, the inner diameter of the furnace core of a heating furnace is the minimum necessary inner diameter compared to the dimensions of the object to be heated, in order to achieve high heating efficiency and uniformity of temperature within the heating furnace. Especially in the case of a basket holder, the gap is at most several liters to several tens of millimeters, so for example, when the basket holder vibrates from side to side, the amplitude of the vibration is at least as large as that. Must be allowed within the range.
