- the substrate processing apparatus 10 mainly includes a reaction tube storage chamber 206 and a transfer chamber 217.
- the reaction tube storage chamber 206 is disposed above the transfer chamber 217.
- the reaction tube storage chamber 206 includes a cylindrical reaction tube 210 extending vertically, a heater 211 as a heating part (furnace body) installed on the outer periphery of the reaction tube 210, a treatment gas supply structure 212 as a first gas supply part, and a gas exhaust structure 213 as an exhaust part.
- the reaction tube 210 is also called a treatment chamber, and the space inside the reaction tube 210 is also called a treatment space.
- the reaction tube 210 is capable of storing a substrate holder (substrate holder) 300, which will be described later.
- the substrate holder 300 that holds the substrate S is carried into the processing chamber 201 formed by the reaction tube 210.
- the substrate S is then processed in the processing chamber 201.
- the processing gas supply structure 212, the inside of the reaction tube 210, and the gas exhaust structure 213 are horizontally connected.
- the process gas supply structure 212 is provided on the side of the reaction tube 210, upstream in the gas flow direction, and gas is supplied from the process gas supply structure 212 to the process chamber 201 inside the reaction tube 210, and the gas is supplied horizontally to the substrate S.

- An upstream straightening section 214 that straightens the flow of gas supplied from the process gas supply structure 212 is provided on the upstream side of the reaction tube 210 between the reaction tube 210 and the process gas supply structure 212.
- a downstream straightening section 215 that straightens the flow of gas exhausted from the reaction tube 210 is provided on the downstream side of the reaction tube 210 between the reaction tube 210 and the gas exhaust structure 213.
- the lower end of the reaction tube 210 is supported by a manifold 216.
- the reaction tube 210, the upstream rectifier 214, and the downstream rectifier 215 have a continuous structure and are formed of materials such as quartz or SiC. These are made of a heat-transmitting material that transmits the heat radiated from the heater 211.
- the heat from the heater 211 heats the substrate S and the gas.
- the heater 211 also has a resistance heater that can be controlled to turn on/off and control the heating temperature.
- the heater 211 is disposed to the side of the processing chamber 201 and is configured to be able to heat the processing chamber 201.
- the processing area A and the insulating area B are arranged so that they are in contact with each other within the reaction tube 210. However, this is not necessarily limited to this, and they may be separated from each other, or may be arranged so that they partially overlap each other.
- An upstream flow straightening unit 214 is disposed between the process gas supply structure 212 and the reaction tube 210 .
- the upstream straightening section 214 has a housing 227 and a partition plate 226.
- the partition plate 226 extends horizontally.
- the horizontal direction here refers to the direction of the side wall of the housing 227.
- Multiple partition plates 226 are arranged vertically.
- the partition plates 226 are fixed to the side wall of the housing 227 and are configured so that gas does not move beyond the partition plate 226 to the adjacent area below or above. By preventing gas from moving beyond the partition plate 226, the gas flow described below can be reliably formed.
- Gas ejected from nozzles 223 and 224 is supplied to the surface of substrate S.
- gas when viewed from substrate S, gas is supplied from the side of substrate S.
- partition plate 226 extends horizontally and has a continuous structure with no holes, the main flow of gas is restricted from moving vertically and moves horizontally. Therefore, the pressure loss of the gas reaching each substrate S can be made uniform across the vertical direction.
- a downstream straightening section 215 is disposed downstream of the reaction tube 210 in the gas flow direction, i.e., between the reaction tube 210 and the gas exhaust structure 213.
- the downstream straightening section 215 is configured so that when the substrate S is held by the substrate holder 300, which serves as a substrate holder for holding the substrate S, the ceiling of the downstream straightening section 215 is higher than that of the substrate S arranged at the top, and the bottom of the downstream straightening section 215 is configured so that the bottom of the downstream straightening section 215 is lower than that of the substrate S arranged at the bottom of the substrate holder 300.
- the downstream straightening section 215 has a housing 231 and a partition plate 232.

- multiple partition plates 232 are arranged in the vertical direction.
- the partition plates 232 are fixed to the side wall of the housing 231 and are configured so that the gas does not move beyond the partition plate 232 to the adjacent area below or above. By preventing the gas from moving beyond the partition plate 232, the gas flow described below can be reliably formed.
- the upstream straightening section 214 communicates with the space of the downstream straightening section 215 via the processing chamber 201.
- the ceiling of the housing 227 is configured to be at the same height as the ceiling of the housing 231.
- the bottom of the housing 227 is configured to be higher than the bottom of the housing 231.
- the partition plates 232 are provided at positions corresponding to the respective substrates S, and at positions corresponding to the respective partition plates 226. It is desirable that the corresponding partition plates 226 and partition plates 232 have the same height. Furthermore, when processing the substrate S, it is desirable to align the height of the substrate S with the heights of the partition plates 226 and 232. With this structure, the gas supplied from each nozzle forms a horizontal flow passing over the substrate S and the partition plate 232, as shown by the arrows in the figure. With the partition plate 232 structured in this way, the pressure loss of the gas exhausted from each substrate S can be made uniform. Therefore, the gas flow of the gas passing through each substrate S is formed horizontally toward the gas exhaust structure 213, while the vertical flow is suppressed.
- the pressure loss can be made uniform in the vertical direction upstream and downstream of each substrate S, so that a horizontal gas flow can be reliably formed with vertical flow suppressed across the partition plate 226, over the substrate S, and across the partition plate 232.
- a partition plate 226 is provided for each of the multiple substrates S, and the space partitioned by the housing 227 and the partition plate 226 is used as multiple gas supply holes that supply processing gas toward the upper surface of the substrate S.
- a partition plate 232 is provided for each of the multiple substrates S, and the space partitioned by the housing 231 and the partition plate 232 is used as multiple second exhaust holes that connect the processing chamber 201 to the second exhaust pipe 281. In this way, by providing a gas supply hole and a second exhaust hole for each substrate S, the uniformity of processing on the multiple substrates S can be improved.
- the gas exhaust structure 213 is provided downstream of the downstream straightening section 215.
- the gas exhaust structure 213 is mainly composed of a housing 241 and an exhaust hole 244.
- the gas exhaust structure 213 has a buffer section 242, which is a space where gas exhausted from the second exhaust holes of the partition plate 232 join together and is exhausted by an exhaust system 280 described later. In this way, the flow rate of the gas exhausted from each second exhaust hole is uniformed by the buffer section 242, and the uniformity of processing on multiple substrates S can be improved.
- the exhaust hole 244 is formed on the downstream side of the housing 241, on the lower side or in the horizontal direction.
- An exhaust pipe 281 is connected to the processing chamber 201 via the exhaust hole 244.
- Gas exhaust structure 213 communicates with the space of downstream straightening section 215.
- Housings 231 and 241 have a continuous height structure.
- the ceiling of housing 231 is configured to be at the same height as the ceiling of housing 241, and the bottom of housing 231 is configured to be at the same height as the bottom of housing 241.
- the gas exhaust structure 213 is a lateral exhaust structure that is provided laterally of the reaction tube 210 and exhausts gas from the lateral direction of the substrate S.
- the bottom surface of the housing 231 is configured so that a thermocouple 500 can be installed.
- a thermocouple 500 By configuring the bottom of the housing 231 lower than the bottom of the housing 227 and configuring the space of the downstream rectifier 215 to be wider than the space of the upstream rectifier 214, it is possible to ensure a place to install the thermocouple 500 while preventing the inert gas supplied to the insulating section 502 and the atmosphere of the insulating region B (including reaction by-products) from flowing into the processing region A.
- the gas flow of the gas passing through each substrate S is formed horizontally toward the gas exhaust structure 213 while the vertical flow is prevented.
- the gas that has passed through the downstream straightening section 215 is exhausted from the exhaust hole 244.
- the gas exhaust structure 213 does not have a configuration such as a partition plate, a gas flow including a vertical direction is formed toward the exhaust hole 244.
- the substrate holder 300 housed in the reaction tube 210 includes a partition plate holder 310 and a base 311 .
- a number of disk-shaped partitions 314 are fixed to the partition holder 310 at a predetermined pitch.
- the partitions 314 are configured to hold the substrates S at predetermined intervals between them.
- the partitions 314 are disposed directly below the substrates S, and either above or below the substrate S, or both.
- the partitions 314 block the space between the substrates S.
- the substrate holder 300 holds multiple substrates S stacked vertically at a predetermined interval.
- the predetermined interval between the multiple substrates S placed on the substrate holder 300 is the same as the vertical interval between the partition plates 314 fixed to the partition plate holding section 310.
- the diameter of the partition plate 314 is also formed to be larger than the diameter of the substrates S.
- the substrate holder 300 holds multiple substrates S, for example five substrates S, in multiple stages in the vertical direction (perpendicular direction). By processing multiple substrates S at once in this manner, productivity can be improved. Note that, although an example in which the substrate holder 300 holds five substrates S is shown here, this is not limiting. For example, the substrate holder 300 may be configured to be able to hold approximately 5 to 50 substrates S.
- the substrate S held by the substrate holder 300 can be placed in processing area A within the processing chamber 201, and a process of forming a thin film on the surface of the substrate S can be performed. Furthermore, inside the transfer chamber 217, the details of which will be described later, the substrate S held by the substrate holder 300 can be transferred by a vacuum transfer robot (not shown) through a substrate loading port (not shown), and the transferred substrate S can be transported into the reaction tube 210, where a process of forming a thin film on the surface of the substrate S can be performed.

- a flush supply of the processing gas is performed.
- a pressure difference occurs between processing area A and insulating area B in the initial stage of the flush supply, and if the pressure in processing area A becomes higher than that in insulating area B, the processing gas will flow down from processing area A toward insulating area B, which may result in interference with uniform processing of the substrate S.
- the inert gas supply system 270 supplies inert gas to the insulating region B so that the pressure difference between the processing region A and the insulating region B is small when flushing the processing gas (at least one of the first processing gas or the second processing gas, preferably both). More specifically, in order to supply inert gas so as to reduce the pressure difference between the processing region A and the insulating region B when flushing the processing gas, the first processing gas supply system 250 and the second processing gas supply system 260 as the first gas supply unit and the inert gas supply system 270 as the second gas supply unit are controlled according to control instructions from the controller 600.
- the pressure difference is reduced means that the pressure difference between the processing area A and the insulating area B does not exceed a predetermined allowable value that is assumed in advance. In other words, it means that the pressure difference between the processing area A and the insulating area B is equal to or less than a predetermined allowable value, and that the pressures of the processing area A and the insulating area B are recognized to be equivalent, and more preferably, that the pressures are the same.
- the predetermined allowable value is set, for example, so that the pressure difference between the processing area A and the insulating area B is within a range of about -10% to 10%.
- the inert gas flowing into the insulating area B may flow into the processing area A, diluting the processing gas and deteriorating the uniformity between the surfaces.
- the pressure difference exceeds 10%, the processing gas may flow into the insulating area B, causing by-products to adhere to the furnace opening such as the insulating section and the manifold.

- gas charging into the third flash tank 279 is performed until the gas charge amount reaches a range of 30 kPa to 50 kPa. Gas charging may be performed in advance before starting the supply of the inert gas.
- the valve 277 is opened. This allows the inert gas stored in the third flash tank 279 to be supplied to the insulating region B in the processing chamber 210 at a large flow rate in a short period of time. In this way, it is possible to perform a flush supply of the inert gas by the inert gas supply system 270 as in the case of the processing gas supply described above.
- the flush supply of inert gas by the inert gas supply system 270 is performed in synchronization with the flush supply of the first process gas (raw material gas) to the process area A in the first step described above, and in synchronization with the flush supply of the second process gas (reaction gas or modifying gas) to the process area A in the third step described above.
- the first process gas is flushed in the first step
- a flush supply of inert gas to the insulating area B is performed in synchronization with this
- the second process gas is flushed in the third step
- a flush supply of inert gas to the insulating area B is performed in synchronization with this.
- synchronized means that each flash supply is performed at the same time, and specifically includes cases where the flash supplies start and end at the same time, as well as cases where the timing is off to the extent that it can be considered simultaneous, even if it is not completely simultaneous.
- the supply of inert gas to insulating region B is performed at the same time as the flush supply of processing gas to processing region A (including cases where there is a lag that can be considered to be simultaneous). At that time, the inert gas is also flushed into insulating region B.
- the inert gas is supplied to the insulating region B at a predetermined flow rate or flow speed.
- the predetermined flow rate or flow speed is set in advance so that the pressure difference between the processing region A and the insulating region B is small.
- the flow rate of the first gas which is the processing gas
- the processing gas includes a first processing gas supplied in the first step and a second processing gas supplied in the third step, and the flow rates of the first processing gas and the second processing gas may be the same or different from each other.
- the flow rate of the inert gas which is the second gas, is set according to the volume ratio between the processing area A and the insulating area B.
- the volume of the processing area A is 1 to 500 L, preferably 5 to 300 L, and more preferably 10 to 200 L.
- the volume of the insulating area B is 0.5 to 300 L, preferably 1 to 200 L, and more preferably 5 to 100 L.
- the flow rate of the inert gas is 0.1 to 200 slm, preferably 0.2 to 150 slm, and more preferably 0.3 to 60 slm.
- the flow rates of the inert gas supplied in the first step and the inert gas supplied in the third step are also different from each other according to the flow rates of the first processing gas and the second processing gas.
- the supply of inert gas to the insulating region B to prevent backflow of the processing gas and adhesion of by-products can be achieved through the gas supply holes 291 and gas supply pipes 292 located opposite the gas exhaust structure 213, which allows the flow of the inert gas to be smooth. This is therefore highly desirable in terms of ensuring the prevention of backflow of the processing gas and the prevention of adhesion of by-products.
- the supply of the inert gas to the insulating region B may be by a control mode such as that of a second specific example described below, instead of by the flush supply described in the first specific example above.
- the valves 274 and 277 are opened. This causes the inert gas from the inert gas supply system 270 to be supplied to the insulating region B in the processing chamber 210.
- the timing of supplying the inert gas by the inert gas supply system 270 is such that the supply of the inert gas to the insulating region B is started prior to the start of the flush supply of the first process gas (raw material gas) to the process region A in the first step, and the supply of the inert gas to the insulating region B is started prior to the start of the flush supply of the second process gas (reaction gas or modifying gas) to the process region A in the third step.
- the supply of the inert gas to the insulating region B is made before the flush supply of the first process gas in the first step, and the supply of the inert gas to the insulating region B is made before the flush supply of the second process gas in the third step.
- the inert gas supply system 270 starts supplying the inert gas a preset predetermined time before the start of the flush supply of the first or second process gas.
- the "predetermined time” is set to a sufficient time from the start of the supply of the inert gas to the insulating region B until the inert gas can be supplied to the insulating region B at a preset flow rate or flow speed.
- the flow rate or flow speed of the inert gas may be the same as in the first specific example described above.
- the flush supply of the first process gas (raw material gas) to the process area A in the first step and the flush supply of the second process gas (reaction gas or modifying gas) to the process area A in the third step may be performed intermittently multiple times in each of the first and third steps, as shown in Figures 8 and 9.
- the supply of inert gas to the insulating region B by the inert gas supply system 270 can be synchronized with the respective flush supplies of the first and second processing gases, as shown in FIG. 8, and can be performed intermittently multiple times in each of the first and third steps.
- the pressure difference between the processing region A and the insulating region B can be reduced, as in the first specific example, and the effect of preventing backflow of the processing gas and adhesion of by-products can be obtained.
- the supply of inert gas to the insulating region B by the inert gas supply system 270 can be performed, for example, as shown in FIG. 9, before the initial flush supply of the processing gas in each of the first and third steps.
- the gas supply to the processing region A and the insulating region B in such a controlled manner the pressure difference between the processing region A and the insulating region B can be reduced, as in the case of the second specific example, and the effect of preventing backflow of the processing gas and adhesion of by-products can be obtained.
- the first gas supply unit and the inert gas second gas supply unit that supply the processing gas are controlled so that the second gas, which is the inert gas (purge gas), is supplied so that the pressure difference between the first region, which is the processing region A, and the second region, which is the insulating region B, is reduced.
- the pressure difference between the processing region A and the insulating region B can be reduced, so that the effect of preventing the processing gas supplied to the processing region A from flowing back into the insulating region B and the effect of preventing the adhesion of by-products to the insulating region B are obtained, which is very favorable for realizing uniform processing for each substrate S.
- the inert gas is supplied to the heat insulating region B through the gas supply holes 291 and gas supply pipes 292 that are provided in a position opposite the gas exhaust structure 213, so that the flow of the inert gas can be made smooth. This is therefore very preferable in terms of ensuring the effect of preventing backflow of the processing gas and the effect of preventing adhesion of by-products.
- a film is formed on the substrate S using a first processing gas and a second processing gas in the film formation process performed by the substrate processing apparatus, but the present embodiment is not limited to this.

基板を処理するための処理室と、
前記処理室内の第1領域に第1ガスを供給する第1ガス供給部と、
前記処理室内の第1領域とは異なる第2領域に第2ガスを供給する第2ガス供給部と、
前記第1ガスをフラッシュ供給する際に、前記第1領域と前記第2領域との圧力差が小さくなるように前記第2ガスを供給するよう前記第1ガス供給部と前記第2ガス供給部とを制御することが可能なよう構成される制御部と、
を有する技術が提供される。
本開示の一態様に係る基板処理装置の構成について、図1を用いて説明する。
基板処理装置10は、大別すると、反応管格納室206と、移載室217とを備える。反応管格納室206は移載室217上に配される。
反応管格納室206は、鉛直方向に延びた円筒形状の反応管210と、反応管210の外周に設置された加熱部(炉体)としてのヒータ211と、第1ガス供給部としての処理処理ガス供給構造212と、排気部としてのガス排気構造213とを備える。ここでは、反応管210は処理室とも呼び、反応管210内の空間を処理空間とも呼ぶ。
処理ガス供給構造212には、ガス供給管251、ガス供給管261が接続される。また、処理ガス供給構造212は、各ガス供給管から供給されたガスを分配する分配部125を有する。分配部125の下流側にはノズル223、ノズル224が設けられる。ガス供給管251、ガス供給管261の下流側には、分配部125を介して、複数のノズル223,224がそれぞれ接続されている。ノズル223とノズル224は略水平に横並びに配される。また、これらのノズル223,224が、鉛直方向に複数配され、それぞれ基板Sに対応した位置に配される。処理ガスは、処理室201に基板Sが存在する状態で、基板Sの側方から供給される。
処理ガス供給構造212と反応管210との間には、上流側整流部214が配されている。
ガス排気構造213は下流側整流部215の下流に設けられる。ガス排気構造213は主に筐体241と排気孔244とで構成される。ガス排気構造213は、区画板232のそれぞれである第2の排気孔から排気されたガスが合流し、後述する排気系280によって排気される空間であるバッファ部242を有している。このようにして、それぞれの第2の排気孔から排気されるガスがバッファ部242によって流量が均一化され、複数の基板Sへの処理の均一性を向上させることができる。排気孔244は、筐体241の下流側であって下側もしくは水平方向に形成されている。処理室201に排気孔244を介して排気管281が接続される。
反応管210内に格納される基板保持具300は、仕切板保持部310と基部311を備える。
反応管210内において、基板保持具300の下方には、断熱部502が設けられている。
反応管格納室206の下方に配される移載室217は、反応管210の下部に位置するマニホールド216を介して設置される。移載室217では、基板搬入口を介して真空搬送ロボットにより基板Sを基板保持具(以下、単にボートと記す場合もある)300に載置(搭載)したり、真空搬送ロボットにより基板Sを基板保持具300から取り出したりすることが行われる。
続いてガス供給系の詳細を説明する。
処理ガス供給系(すなわち第1ガス供給部)における第一処理ガス供給系250は、ガス供給管251を通じて処理領域Aに対するガス供給を行う。そのため、図2(A)及び図3に示すように、ガス供給管251には、上流方向から順に、第一ガス源252、流量制御器(流量制御部)であるマスフローコントローラ(MFC)253、開閉弁であるバルブ254、ガスを貯留する貯留部であるタンク(以下「第一のフラッシュタンク」ともいう。)259及びバルブ275が設けられている。ガス供給管251には、デジタルゲージ251aが接続されていてもよい。
処理ガス供給系(すなわち第1ガス供給部)における第二処理ガス供給系260は、ガス供給管261を通じて処理領域Aに対するガス供給を行う。そのため、図2(B)及び図3に示すように、ガス供給管261には、上流方向から順に、第二ガス源262、MFC263、バルブ264、ガスを貯留する貯留部であるタンク(以下「第二のフラッシュタンク」ともいう。)269及びバルブ276が設けられている。ガス供給管261には、デジタルゲージ261aが接続されていてもよい。
不活性ガス供給系270(すなわち第2ガス供給部)は、ガス供給管292を通じて断熱領域Bに対するガス供給を行う。そのため、図2(C)に示すように、ガス供給管271には、上流方向から順に、不活性ガス源272、MFC273、バルブ274、ガスを貯留する貯留部であるタンク(以下「第三のフラッシュタンク」ともいう。)279及びバルブ277が設けられている。不活性ガス源272からは不活性ガス、例えばN2ガスが供給される。
続いてガス排気系について図1を用いて説明する。
続いて基板処理装置10の制御部(制御手段)であるコントローラについて図4を用いて説明する。
次に、半導体製造工程(半導体装置の製造方法)の一工程として、上述した構成の基板処理装置10を用いて基板S上に膜を形成する工程について説明する。なお、以下の説明において、基板処理装置10を構成する各部の動作はコントローラ600により制御される。
まず、移載室圧力調整工程(S10)を説明する。ここでは、移載室217内の圧力を移載室217に隣接する図示しない真空搬送室と同レベルの圧力とする。
続いて基板搬入工程(S11)を説明する。移載室217が真空レベルとなったら、基板Sの搬送を開始する。基板Sが真空搬送室に到着したらゲートバルブを解放し、真空搬送ロボットは基板Sを移載室217に搬入する。
続いて加熱工程(S12)を説明する。反応管210内である処理室201に基板Sを搬入したら、反応管210内を所定の圧力となるように制御するとともに、基板Sの表面温度が所定の温度となるようにヒータ211を制御する。温度は、例えば400℃以上800℃以下に加熱する。好ましくは500℃以上であって700℃以下である。圧力は例えば50から5000Paとすることが考えられる。
続いて膜処理工程(S13)を説明する。膜処理工程(S13)では、プロセスレシピに応じて、基板保持具300に積層された基板Sが処理室に収容された状態で、基板Sに対してガス供給を行い、基板S上に所望の膜を形成する。
続いて基板搬出工程(S14)を説明する。基板搬出工程(S14)では、上述した基板搬入工程(S11)と逆の手順にて、処理済みの基板Sを移載室217の外へ搬出する。
続いて判定(S15)を説明する。ここでは所定回数基板を処理したか否かを判定する。所定回数処理していないと判断されたら、基板搬入工程(S11)に戻り、次の基板Sを処理する。所定回数処理したと判断されたら、処理を終了する。
次に、上述した基板処理工程の膜処理工程(S13)において、反応管210(処理室201)へのガス供給を行う際の手順を、図2及び図3を用いて説明する。
第一工程では、まず、バルブ254を開状態としつつバルブ275を閉状態とし、これにより第一のフラッシュタンク259内への第一処理ガス(原料ガス)のガスチャージを行う。第一のフラッシュタンク259へのガスチャージは、例えば、タンク容量が1000ccである場合に、ガスチャージ量が30kPa~50kPaの範囲内に達するまで行う。ガスチャージは、第一工程の開始前に予め行っておいてもよい。
第一工程の開始から所定時間経過後に行う第二工程では、処理室201内のパージを行う。そのために、第二工程では、バルブ254を閉じて、第一処理ガスの供給を停止した状態で、バルブ258,275,268,276,274,277等を開き、ガス供給管255,265,271,701内に、パージガスとしての不活性ガスを供給すると共に、排気管281のバルブ282、APCバルブ283は開いたままとして、真空ポンプ284により反応管210内を真空排気する。
第二工程の開始から所定時間経過後に行う第三工程では、第一工程の場合と同様に、まず、バルブ264を開状態としつつバルブ276を閉状態とし、これにより第二のフラッシュタンク269内への第二処理ガス(反応ガスまたは改質ガス)のガスチャージを行う。第二のフラッシュタンク269へのガスチャージは、例えば、タンク容量が1000ccである場合に、ガスチャージ量が30kPa~50kPaの範囲内に達するまで行う。ガスチャージは、第一工程の開始前に予め行っておいてもよい。
第三工程の開始から所定時間経過後に行う第四工程では、処理室201内のパージを行う。そのために、第四工程では、バルブ264を閉じて、第二処理ガスの供給を停止した状態で、バルブ258,275,268,276,274,277等を開き、ガス供給管255,265,271,701内に、パージガスとしての不活性ガスを供給すると共に、排気管281のバルブ282、APCバルブ283は開いたままとして、真空ポンプ284により反応管210内を真空排気する。これにより、反応管210内に存在する、気相中の第一処理ガスと第二処理ガスの反応を抑制することができる。
以上のような第一工程から第四工程までの各工程を順に非同時に行うサイクルを所定回数(n回、nは1以上の整数)行う。これにより、基板S上に、所定の厚さの膜を形成する。ここでは、例えばシリコン窒化(SiN)膜が形成される。
ところで、第一工程では、処理領域Aに位置する基板Sに対して第一処理ガスの供給を行う。また、第三工程では、処理領域Aに位置する基板Sに対して第二処理ガスの供給を行う。このとき、処理領域Aの下方の断熱領域Bに対しては、不活性ガス供給系270により不活性ガスを供給すると、第一処理ガスや第二処理ガスや反応副生成物が断熱領域Bの側に流入して断熱部502に膜が堆積されるのを抑制することができる。
不活性ガス供給系270による断熱領域Bへの不活性ガスの供給を行う際には、図2(C)において、まず、バルブ274を開状態としつつバルブ277を閉状態とし、これにより第三のフラッシュタンク279内への不活性ガス(パージガス)のガスチャージを行う。第三のフラッシュタンク279へのガスチャージは、例えば、タンク容量が1000ccである場合に、ガスチャージ量が30kPa~50kPaの範囲内に達するまで行う。ガスチャージは、不活性ガスの供給の開始前に予め行っておいてもよい。
断熱領域Bへの不活性ガスの供給は、上述の第一具体例で説明したフラッシュ供給によるものではなく、以下に説明する第二具体例のような制御態様によるものでもよい。
第一工程での処理領域Aへの第一処理ガス(原料ガス)のフラッシュ供給及び第三工程での処理領域Aへの第二処理ガス(反応ガスまたは改質ガス)のフラッシュ供給については、図8及び図9に示すように、第一工程及び第三工程のそれぞれで複数回にわたり断続的に行われることもあり得る。
本実施形態によれば、以下に示す一つまたは複数の効果を奏する。
以上に、本開示の一実施形態を具体的に説明したが、本開示が上述の実施形態に限定されることはなく、その要旨を逸脱しない範囲で種々変更が可能である。
