A technique that is effectively used in a semiconductor device such as a heat treatment device used for reflow or thermal treatment in thermal treatment. Background of the Invention In the 1C manufacturing method, a batch type upright type hot wall type diffusion CVD apparatus is widely used for performing a film forming process and a diffusion process 4 on a wafer. In general, a batch type upright type hot wall type diffusion CVD apparatus (hereinafter referred to as a CVD apparatus) includes a reaction tube which is formed of an inner tube forming a processing chamber for feeding a wafer and an outer tube surrounding the inner portion, and is provided in an upright type. a wafer boat holding a plurality of wafers as substrates to be processed and feeding them into a processing chamber of the inner tube; the gas introduction tube 'inducing the raw material gas into the inner tube; exhausting f to exhaust the inside of the reaction tube; The unit is disposed outside the reaction tube and heats the inside of the reaction tube. Further, in a state where the plurality of wafers are arranged and held in the vertical direction by the boat, the raw material gas is guided from the guide tubes into the inner tube after being fed into the inner tube from the lower end of the furnace port. And the reaction tube is heated by a 20-port hot state unit. Thereby, the CVD vapor deposition treatment is performed. The film is deposited on a wafer, and in the conventional CVD apparatus, as a heating furnace, the heater unit has the following structure, that is, the heat insulating wall body is used, and the oxidation furnace or the second layer is used. The heat insulating material 'is formed by a vacuum forming (vacuum adsorption forming) method to form a long cylindrical shape integrally covering the reaction tube; the heating element is formed longer by using an iron chromium aluminum shame~ A1) alloy or a molybdenum molybdenum (M〇si2); And a housing, the t cover heat insulating wall body; and the heat generating body is disposed on the inner circumference of the heat insulating wall body. In the above-described heater unit, when the fish heating is performed at a speed of, for example, 3 〇χ:/min or more, the heat generating body formed into a shape is used in order to increase the heat-generating effective area. Further, when the plate-shaped heat generating body is used, the power supply unit for energizing the heat generating body is configured as follows. The both end portions of the plate-shaped heat generating body are bent at right angles in the thickness direction to form a pair of power supply portions, and the pair of power supply portions penetrate the heat insulating wall body, and the through portion of the snow supply portion is bent at a right angle. A power supply terminal is connected to the bent portion. In order to prevent the pair of power supply portions from being warped due to thermal expansion during heat generation, they are held by the insulator. For example, refer to Patent Document i. In the above-described holding structure of the heat generating body, the narrower distribution is advantageous for the heating distribution. Therefore, the interval between the pair of feeding portions of the heating element is often set to be narrow. However, when the interval between the pair of power supply portions of the heat generating body is set to be narrow, both ends of the heat generating body are brought into a close state. On the other hand, if the temperature of the heating element rises, it will expand due to thermal expansion.

如第2及5圖所示’在加熱器單元3〇的殼體31的外周面 上與供電端子51的設置場所對應的位置,覆蓋著包覆兩個 連接部47、48及搭接線62的端子殼體63,在端子殼體63的 内部填充有玻璃纖維等隔熱材料64。在端子殼體63中經由 絕緣子65插入有多個供電端子61。 接著’簡單地說明利用有關上述結構的Cvd裝置來製 造1C等半導體裝置的製造方法的成膜工序。 如第1圖所示’如果將多片薄片1裝填在晶舟22上(晶片 裝料)’則保持了多片晶片1的晶舟22被晶舟升降機21提起 而送入到處理室11中(晶舟裝載)。 19 1308364 在該狀態下’密封蓋20成爲將岐管16的下端開口密封 的狀態。 反應管11的内部通過排氣管17被真空排氣,成爲規定 的壓力(真空度)。 此外’反應管11的内部被加熱器單元30加熱,成爲規 定的温度。此時,根據溫度感測器24所檢測到的溫度資訊, 反饋控制向加熱器單元30的發熱體42的通電狀況,以使處 理室14内成爲規定的溫度分佈。 接著’晶舟22通過旋轉機構25被旋轉,由此晶片1旋轉。 接著’通過氣體導入管23將控制爲規定流量的原料氣 體向處理室14内導入。 被導入的原料氣體在處理室14内上升,從内管13的上 端開口流出到排氣通路18,然後從排氣管17被排放。 15As shown in FIGS. 2 and 5, 'the outer peripheral surface of the casing 31 of the heater unit 3A corresponds to the installation place of the power supply terminal 51, and covers the two connecting portions 47, 48 and the bonding wires 62. The terminal housing 63 is filled with a heat insulating material 64 such as glass fiber inside the terminal housing 63. A plurality of power supply terminals 61 are inserted into the terminal housing 63 via the insulator 65. Next, a film forming step of manufacturing a semiconductor device such as 1C using the Cvd device having the above configuration will be briefly described. As shown in Fig. 1, if the plurality of sheets 1 are loaded on the wafer boat 22 (wafer loading), the wafer boat 22 holding the plurality of wafers 1 is lifted by the boat elevator 21 and fed into the processing chamber 11. (Crystal loading). 19 1308364 In this state, the seal cap 20 is in a state in which the lower end opening of the manifold 16 is sealed. The inside of the reaction tube 11 is evacuated by the exhaust pipe 17 to have a predetermined pressure (degree of vacuum). Further, the inside of the reaction tube 11 is heated by the heater unit 30 to have a predetermined temperature. At this time, based on the temperature information detected by the temperature sensor 24, the energization state of the heating element 42 to the heater unit 30 is feedback-controlled so that the inside of the processing chamber 14 becomes a predetermined temperature distribution. Then, the wafer boat 22 is rotated by the rotating mechanism 25, whereby the wafer 1 is rotated. Then, the raw material gas controlled to a predetermined flow rate is introduced into the processing chamber 14 through the gas introduction pipe 23. The introduced material gas rises in the processing chamber 14, flows out from the upper end opening of the inner tube 13 to the exhaust passage 18, and is discharged from the exhaust pipe 17. 15

原料氣體在通過處理室14内時與晶片丨的表面接觸,此 時,通過熱CVD反應將薄膜沈積在晶片1的表面上。 如果經過了預先設定的處理時間,則從惰性氣體供給 源(未圖示)供給惰性氣體,處理室14内被置換爲惰性氣體, 並且使處理室14内的壓力恢復到常壓。 然後,通過晶舟升降機21使密封蓋2〇下降,將岐管16 20的下端開口,並且在將處理後的晶片1保持在晶舟22上的狀 態下,從岐管16的下端送出到反應管u的外部(晶舟卸載)。 然後’將處理後的晶片1從晶舟22中取出(晶片卸料)。 但是,加熱器單元30的發熱體42如果溫度上升,則因 熱膨脹而伸長。此外,發熱體42因長時間使用也有伸長的 20 1308364 趨勢。 例如,如第6(a)圖所示,由於發熱體42的一對供電部 45、46的間隔設定得較窄,所以如果發熱體42伸長,則一 • 對供電部45、46的間隔變窄、最終接觸,從而有可能發生 電氣短路、或在温度較高的情況下會相互熔接。 特別是,如第3(a)、3(b)圖所示,由於在供電部附近需 要設置标通槽49、50和内側絕緣子55,所以不能很好地配 置保持用具41以保持發熱體42的圓筒部51,所以發熱體42 變得容易向圓周方向伸長,所以易發生上述那樣的問題。 此外,有時保持用具41會因發熱體42的翹曲而從破裂 的隔熱塊36脫落、或向圓筒部51的圓周方向偏移。此時, 對供電部45、46的間隔變窄、最終接觸,由此,有可能 發生電氣短路、或在溫度較高時相互炼接。 - 但是,在本實施方式中,一對的供電部45、46通過外 15側絕緣子52及内側絕緣子Μ被保持成相互絕緣的狀態,並 且在内側絕緣子55上,在兩個供電部45、46之間以及比圓 筒部51靠半徑方向内侧設有隔壁部58,所以,如第6(b)圖所 示’即使在發熱體42伸長的情況下,也能夠防止一對供電 部45、46彼此及圓筒部51的接觸,能夠將發熱體42的短路 2〇 和熔接防止於未然。 根據上述實施方式,能夠得到下面的效果。 (1)通過由外側絕緣子及内側絕緣子保持發熱體的一 對供電部、並且在内側絕緣子上設置阻止兩個供電部和發 熱體的圓筒部的接觸的隔壁部’即使在發熱體伸長的情況 21 1308364 下,也能娜止-對供電部彼此及發熱義圓筒部接觸, 所以肖b將發熱體的短路及炫接防止於未然。 (2)通過將發熱體的短路及賴防止於未然,能夠延長 發熱體的壽命。 ~ 5The material gas is brought into contact with the surface of the wafer cassette while passing through the processing chamber 14, and at this time, a thin film is deposited on the surface of the wafer 1 by a thermal CVD reaction. When a predetermined processing time elapses, the inert gas is supplied from an inert gas supply source (not shown), the inside of the processing chamber 14 is replaced with an inert gas, and the pressure in the processing chamber 14 is returned to the normal pressure. Then, the sealing cover 2 is lowered by the boat elevator 21, the lower end of the manifold 16 20 is opened, and in the state where the processed wafer 1 is held on the boat 22, the reaction is sent from the lower end of the manifold 16 to the reaction. The outside of the tube u (boat unloading). Then, the processed wafer 1 is taken out from the wafer boat 22 (wafer discharge). However, if the temperature of the heating element 42 of the heater unit 30 rises, it expands due to thermal expansion. In addition, the heating element 42 also has an elongated tendency of 20 1308364 due to long-term use. For example, as shown in Fig. 6(a), since the interval between the pair of feeding portions 45 and 46 of the heating element 42 is set to be narrow, if the heating element 42 is extended, the interval between the feeding portions 45 and 46 is changed. Narrow, final contact, which may cause electrical shorts, or weld at high temperatures. In particular, as shown in FIGS. 3(a) and 3(b), since the mark grooves 49 and 50 and the inner insulator 55 are required to be provided in the vicinity of the power supply portion, the holding tool 41 cannot be disposed well to hold the heat generating body 42. Since the heat generating body 42 is easily elongated in the circumferential direction, the cylindrical portion 51 is liable to cause the above-described problems. Further, the holding tool 41 may be detached from the broken heat insulating block 36 or displaced in the circumferential direction of the cylindrical portion 51 due to the warpage of the heat generating body 42. At this time, the interval between the power supply portions 45 and 46 is narrowed and eventually contacted, whereby electrical short-circuiting may occur or the temperature may be mutually welded when the temperature is high. - In the present embodiment, the pair of power supply portions 45, 46 are held in a state of being insulated from each other by the outer 15 side insulator 52 and the inner insulator, and on the inner insulator 55, at the two power supply portions 45, 46. Since the partition wall portion 58 is provided on the inner side in the radial direction from the cylindrical portion 51, as shown in Fig. 6(b), even when the heat generating body 42 is extended, the pair of power supply portions 45 and 46 can be prevented. The contact between each other and the cylindrical portion 51 prevents the short-circuiting and welding of the heating element 42 from occurring. According to the above embodiment, the following effects can be obtained. (1) A pair of power supply portions that hold the heat generating body by the outer insulator and the inner insulator, and a partition wall portion that prevents contact between the two power supply portions and the cylindrical portion of the heat generating body on the inner insulator, even if the heat generating body is elongated 21 1308364, can also be Na - stop the power supply parts and the heat-resistant cylindrical part, so Xiao b will prevent the short-circuit and stun of the heating element. (2) By short-circuiting the heat generating body and preventing it, the life of the heating element can be prolonged. ~ 5
