この種の縦型基板熱処理装置では、上述した各種処理において、基板間に保持 された大気中の空気とかボロン系ガスや硫酸系ガスや硝酸系ガスといったガスと か重金属などのパーティクルが炉芯管内に混入したり、基板表面に化学的あるい は物理的に吸着した水分等が昇温によって脱離して基板間に滞留した状態で持ち 込まれたりすると品質が低下する問題がある。殊に、ゲート酸化膜のような最近 のプロセスの薄膜化に伴い、その膜質に多大な悪影響を及ぼす問題がある。 In this type of vertical substrate heat treatment equipment, air in the atmosphere, gases such as boron-based gas, sulfuric acid-based gas, nitric acid-based gas, and particles such as heavy metals, etc. However, there is a problem that the quality is deteriorated if it is mixed into the substrate or if moisture or the like that is chemically or physically adsorbed on the substrate surface is desorbed by the temperature rise and is retained between the substrates and is retained. In particular, with the recent thinning of the process such as the gate oxide film, there is a problem that the film quality is greatly adversely affected.

【0003】 そのため、前述した各種処理に先立って、基板間の空気やガスやパーティクル を排除したり、昇温によって基板表面から脱離して基板間に滞留した水分やガス を排除する必要があり、従来では、図3の全体概略縦断面図に示すような手段を 採用している。Therefore, prior to the various treatments described above, it is necessary to remove air, gas, and particles between the substrates, or moisture and gas that are desorbed from the substrate surface due to temperature rise and accumulated between the substrates. Conventionally, the means as shown in the overall schematic vertical sectional view of FIG. 3 has been adopted.

【0004】 図3において、01は炉芯管を示し、その炉芯管01の管軸芯方向の下端側に 開口02が形成され、多数の基板Wを保持した基板ボート03を挿脱するように 構成されている。In FIG. 3, reference numeral 01 denotes a furnace core tube, and an opening 02 is formed at the lower end side of the furnace core tube 01 in the tube axis direction so that a substrate boat 03 holding a large number of substrates W can be inserted and removed. Is configured.

【0005】 炉芯管01の管軸芯方向上端側にガス導入孔04が設けられ、パージガスとし てのN2 ガスやArガスや反応用のプロセスガスを炉芯管01内に導入するよう に構成されている。A gas introduction hole 04 is provided on the upper end side in the axial direction of the furnace core tube 01 so that N 2 gas or Ar gas as a purge gas or a process gas for reaction is introduced into the furnace core tube 01. It is configured.

【0006】 炉芯管01の周囲には、基板Wを加熱する加熱手段としてのヒーターユニット 05が設けられている。 炉芯管01の開口02側に排気フランジ06が設けられ、その排気フランジ0 6の下部開口が炉口キャップ07によりシール状態で閉塞されるとともに、その 排気フランジ06に真空排気装置08が接続されている。A heater unit 05 as heating means for heating the substrate W is provided around the furnace core tube 01. An exhaust flange 06 is provided on the opening 02 side of the furnace core tube 01, a lower opening of the exhaust flange 06 is closed in a sealed state by a furnace port cap 07, and a vacuum exhaust device 08 is connected to the exhaust flange 06. ing.

【0007】 以上の構成により、多数の基板W…を保持した基板ボート03を炉芯管01内 に挿入した後に炉口キャップ07で閉塞し、ヒーターユニット05の温度を酸化 反応を起こさない温度以下に維持しながら、真空排気装置08を作動して真空吸 引排気し、基板W…間にある空気とかガスや水分やパーティクル、および、昇温 によって脱離する水分、ガスを排除するようになっている。With the above configuration, the substrate boat 03 holding a large number of substrates W ... Is inserted into the furnace core tube 01 and then closed by the furnace port cap 07, and the temperature of the heater unit 05 is set to a temperature at which an oxidation reaction does not occur. While maintaining the above, the vacuum exhaust device 08 is operated to perform vacuum suction / exhaust to remove air and gas, water and particles between the substrates W, and water and gas desorbed by the temperature rise. ing.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上述従来例の場合、基板間にある空気とかガスや水分やパーテ ィクル、および、昇温によって脱離する水分、ガスを排除するときには、基板表 面で酸化反応を起こさないように、ヒーターユニット05の加熱温度を本来の熱 処理温度よりも低温に設定しておかなければならない。 However, in the case of the above-mentioned conventional example, when removing air, gas, moisture, particles, and moisture and gas desorbed by temperature rise between the substrates, a heater is used so as not to cause an oxidation reaction on the substrate surface. The heating temperature of the unit 05 must be set lower than the original heat treatment temperature.

【0009】 これに対して、本来の熱処理を行う場合、前処理での空気とかガスや水分やパ ーティクルの排除を終了した後に、ヒーターユニット05の加熱温度を所定の処 理温度まで上昇しなければならない。On the other hand, in the case of performing the original heat treatment, the heating temperature of the heater unit 05 must be raised to a predetermined processing temperature after the removal of air, gas, water and particles in the pretreatment is completed. I have to.

【0010】 これらの結果、ヒーターユニット05において、前処理時の温度と本来の熱処 理時の温度とに切換制御するとともに真空排気装置の制御も必要でシステムが複 雑になって高価になるとともに、所定の真空度まで炉芯管を真空排気するのに相 当の時間が必要であり、ヒーターユニット05による加熱温度を本来の熱処理時 の温度まで上昇するのに時間がかかって単位時間当りの処理能力が低下する欠点 があった。As a result of these, in the heater unit 05, switching control between the temperature at the time of pretreatment and the temperature at the time of the original heat treatment and the control of the vacuum exhaust device are necessary, and the system becomes complicated and expensive. At the same time, it takes a certain amount of time to evacuate the furnace core tube to a predetermined degree of vacuum, and it takes time to raise the heating temperature by the heater unit 05 to the temperature at the time of the original heat treatment. There was a drawback that the processing capacity of

【0011】 本考案は、このような事情に鑑みてなされたものであって、本来の熱処理時と 前処理時相互間での加熱手段による加熱温度の切換えおよび真空排気装置を不用 にして、安価でかつ単位時間当りの処理能力の高い縦型基板熱処理装置を提供で きるようにすることを目的とする。The present invention has been made in view of such circumstances, and it is inexpensive because the heating temperature is switched by the heating means between the original heat treatment and the pretreatment and the vacuum exhaust device is unnecessary. It is an object of the present invention to provide a vertical substrate heat treatment apparatus which has a high processing capacity per unit time.

【考案の効果】[Effect of the device]

以上説明したように、本考案の縦型基板熱処理装置によれば、炉芯管内に基板 ボートを挿入するに伴い、基板ボートに保持された基板間に混入している大気中 の空気やガスやパーティクルや、昇温によって基板表面から脱離して基板間に滞 留しているガスや水分を真空排気装置による真空パージによらずに排除できるか ら、真空排気装置が不要でまた加熱手段による加熱温度に影響されないために、 その加熱温度の切換えをせずに済むので、システムが簡単になって安価である。 As described above, according to the vertical substrate heat treatment apparatus of the present invention, when the substrate boat is inserted into the furnace core tube, the air and gas in the atmosphere mixed between the substrates held in the substrate boat are Particles and gas and moisture desorbed from the substrate surface due to temperature rise and retained between the substrates can be eliminated without vacuum purging by a vacuum exhaust device, so no vacuum exhaust device is required and heating by heating means Since it is not affected by temperature, it is not necessary to switch the heating temperature, so the system is simple and inexpensive.

【0028】 また、上述したように、真空排気装置による真空パージに必要な時間が不要で あり、また、加熱手段による加熱温度に影響されないために、その加熱温度を本 来の熱処理時の温度にしておくことができ、従来のように、加熱手段による加熱 温度を本来の熱処理時の温度まで上昇するのに時間がかかることを回避でき、単 位時間当りの処理能力を向上できる。Further, as described above, the time required for the vacuum purging by the vacuum evacuation device is not necessary, and since the heating temperature by the heating means is not affected, the heating temperature is set to the temperature for the conventional heat treatment. Therefore, it can be avoided that it takes time to raise the heating temperature by the heating means to the temperature at the time of the original heat treatment as in the conventional case, and the processing capacity per unit time can be improved.

【0029】 また、このとき基板は水分、ガスを脱離するに足る温度まで昇温されているか ら、脱離してきたガスや水分を排除することができる。Further, at this time, since the substrate is heated to a temperature sufficient for desorbing moisture and gas, the desorbed gas and moisture can be removed.
