(1) Entire Configuration of Substrate Processing Apparatus

A substrate processing apparatus100includes a process container101serving as a housing for processing to a wafer200. The process container101serves as a sealed container formed of a metal material, such as aluminum (Al) or stainless steel (SUS). Inside the process container101, namely, in a hollow, formed is a process chamber101aserving as a process space for processing to a wafer200. The process container101has a side wall101bprovided with a wafer access port102and a gate valve103that opens/shuts the wafer access port102such that a wafer200can be transferred into/from the process container101through the wafer access port102. The process container101has a side wall101c, opposite the side wall101b, provided with an opening101dhaving an upper portion and a lower portion near which walls101eare provided one-to-one as part of the side wall101c. As illustrated inFIG.1C, in sectional view along the longitudinal direction of the process container101, the process container101has a bottom provided with a protrusion structure101fserving as part of the bottom. Furthermore, the process container101has a gas exhauster including a vacuum pump and a pressure controller (not illustrated) connected thereto such that the pressure in the process container101can be regulated to a predetermined pressure by the gas exhauster.

Inside the process container101, provided is a substrate mounting stage210serving as a substrate mounting table on which a wafer200is mounted and supported. The substrate mounting stage210is gate-shaped in sectional view as illustrated inFIGS.1C and1srectangular in shape in plan view as illustrated inFIG.1A. More specifically, the substrate mounting stage210includes a substrate mounting face210aon which a wafer200is mounted and two side plates210bextending downward one-to-one from both sides of the substrate mounting face210a. The side plates210beach have a lower end secured slidably to a guide rail221.

For direct contact with a wafer200, desirably, the substrate mounting face210ais formed of a material, such as quartz (SiO2) or alumina (Al2O3). For example, preferably, a susceptor, serving as a support plate formed of quartz or alumina, is mounted on the substrate mounting face210aand then a wafer200is mounted and supported on the susceptor.

As illustrated inFIGS.1B and1C, the substrate mounting stage210(side plate210b) has a lower end coupled with a slider220serving as a mover that reciprocates the substrate mounting stage210and the wafer200on the substrate mounting face in the process container101. The slider220is secured to nearby the bottom of the process container101. The slider220is capable of reciprocating the substrate mounting stage210and the wafer200on the substrate mounting face, horizontally, between one end and the other end in the longitudinal direction of the process container101. For example, the slider220can be achieved with a feed screw (ball screw) and a drive source, such as an electric motor M, in combination.

Below the substrate mounting face210aof the substrate mounting stage210, disposed is a heater unit230that heats a wafer200. The heater unit230includes a plurality of heaters23(e.g., six heaters23). Such a heater23is also referred to as a heating apparatus. The heaters23are each substantially cylindrical in shape and are each disposed along the longitudinal direction of the process container101.

Note that the heater unit230is secured inside the substrate mounting stage210, and the substrate mounting stage210slides outside the heater unit230.

The heater unit230(heaters23) is supported by a support240. The support240includes a prop240aand a box240b. The heater unit230is supported by the box240bthat is open upward and is disposed at the upper end of the prop240aprovided on the bottom (protrusion structure101f) of the process container101.

The heater unit230is provided ranging from one end to the other end in the longitudinal direction of the process container101. One end in the longitudinal direction of the heater unit230is disposed near the side wall101bin the process container101and the other end having penetrated through the opening101dwith which the side wall101cis provided is supported from above and below by the walls101e. The longitudinal direction of the heater unit230(heaters23) is identical to the direction of movement of the substrate mounting stage210. The configuration of the heater unit230(heaters23) will be described in detail later.

A wafer lifter150is on standby below the substrate mounting stage210(substrate mounting face210a). A plurality of lifting pins151(e.g., three lifting pins151) is disposed on the wafer lifter150. The wafer lifter150lifts up/down the lifting pins151. The wafer lifter150and the lifting pins151are, as described later, for use in loading/unloading a wafer200. The substrate mounting stage210is provided with through holes (not illustrated), through which the lifting pins151penetrate one-to-one, at positions corresponding to the lifting pins151.

Above the substrate mounting stage210, provided is a cartridge head assembly300serving as a gas supplier to the wafer200on the substrate mounting stage210. The cartridge head assembly300is larger in size than the entire wafer200and is provided ranging from one end to the other end in the lateral direction of the process container101.

As illustrated inFIG.1A, for example, the cartridge head assembly300includes a single source-gas cartridge330and reactant-gas cartridges340and350. The reactant-gas cartridges340and350are disposed such that the source-gas cartridge330is interposed therebetween.

The source-gas cartridge330includes a source-gas supply line (not illustrated), a source-gas exhaust line (not illustrated), an inert-gas supply line (not illustrated), and an inert-gas exhaust line (not illustrated), in which a common exhaust line may be provided as the source-gas exhaust line and the inert-gas exhaust line. The reactant-gas cartridges340and350each include a reactant-gas supply line (not illustrated), a reactant-gas exhaust line (not illustrated), an inert-gas supply line (not illustrated), and an inert-gas exhaust line (not illustrated), in which a common exhaust line may be provided as the reactant-gas exhaust line and the inert-gas exhaust line. For space separation of source gas and reactant gas, each supply line has an on/off valve (not illustrated), a mass flow controller (not illustrated) that controls a flow rate, and a gas supply source (not illustrated) disposed therein and each exhaust line has a pressure controller (not illustrated) and an exhaust pump (not illustrated) disposed therein.

As the source gas, for example, used can be a silane-based gas containing silicon (Si) serving as a main element for a film to be formed on a wafer200. As the silane-based gas, for example, used can be gas containing Si and halogen, namely, halosilane gas. Halogen includes, for example, chlorine (CI), fluorine (F), bromine (Br), and iodine (I). As the halosilane gas, for example, used can be chlorosilane gas containing Si and Cl. Specifically, dichlorosilane (SiH2Cl2, abbreviation: DCS) gas or hexachlorodisilane (Si2Cl6, abbreviation: HCDS) gas can be used. As the source gas, gas containing a metal, such as titanium (Ti), can be used, in addition to the chlorosilane gas. As a Ti-containing gas, for example, used can be titanium tetrachloride (TiCl4) gas.

As the reactant gas, for example, used can be a nitrogen (N)/hydrogen (H)-containing gas serving as nitriding gas (nitriding agent). Examples of the reactant gas that can be used include hydronitrogen-based gases, such as ammonia (NH3) gas, diazene (N2H2) gas, hydrazine (N2H4) gas, and N3H8gas.

Examples of inert gas that can be used include nitrogen (N2) gas and rare gases, such as argon (Ar) gas, helium (He) gas, neon (Ne) gas, and xenon (Xe) gas.

As illustrated inFIG.1C, the substrate processing apparatus100includes a controller110that controls the operation of each constitute of the substrate processing apparatus100. The controller110serves as a computer including at least an arithmetic section120and a memory130serving as hardware resources. The controller110is connected to each constituent described above. In response to an instruction from a higher-level controller or an operator, the controller110reads, from the memory130, a control program or a process recipe (hereinafter, these are collectively and simply referred to as a “program”) serving as predetermined software and then controls the operation of each constituent in accordance with the description thereof. That is, the controller110executes, with the hardware resources, the program serving as the predetermined software, so that the operation of each constituent of the substrate processing apparatus100is controlled due to the hardware resources and the predetermined software in cooperation. Note that, in the present specification, in some cases, the term “program” indicates the control program, the process recipe, or both thereof.

The controller110as above may be a dedicated computer or may be a general-purpose computer. For example, an external memory140storing the program described above is prepared and then the program is installed on a general-purpose computer through the external memory140, so that the controller110in the present embodiment can be achieved. Note that examples of the external memory140include a magnetic tape, a magnetic disk, such as a flexible disk or hard disk, an optical disc, such as a CD or DVD, a magneto-optical disc, such as an MO, and a semiconductor memory, such as a USB memory or a memory card. For supply of the program to a computer, the supply through the external memory140is not limiting. For example, the program may be supplied through the Internet or a dedicated line or from a higher-level apparatus through a receiver, instead of through the external memory140.

The memory130in the controller110and the external memory140connectable to the controller110each serve as a computer-readable recording medium. Hereinafter, such memories are collectively and simply referred to as a “recording medium”. Note that, in the present specification, in some cases, the term “recording medium” indicates the memory130, the external memory140, or both thereof.

(2) Configuration of Heater23

As illustrated inFIGS.2A and2B, a heater23includes, mainly, a main heater tube500serving as an outer tube, an insulating tube510serving as an inner tube, and a heat emitter540serving as a heater wire.

The main heater tube500includes a main body505substantially cylindrical in shape. The main body505has an end, in its longitudinal direction (axial direction), provided with a support target504to be supported by the walls101eoutside the opening101dof the process container101for setting to the process container101. The main body505(support target504) has the end provided with an opening502enabling the heat emitter540in communication and the other end provided with a lid503. The opening502(support target504) is provided with an O-ring23aenabling the main heater tube500to retain internal airtightness after the main heater tube500(heater23) is set to the process container101.

Outside the main heater tube500, provided is a reflector protective tube520covering the outer circumference of the main heater tube500. The main heater tube500is inserted inside the reflector protective tube520substantially cylindrical in shape.

Between the reflector protective tube520and the main heater tube500, provided is an aligner501that aligns the position of the main heater tube500inside the reflector protective tube520. More specifically, the reflector protective tube520substantially cylindrical in shape has an inner circumferential face provided with the aligner501for alignment such that friction occurs to the main heater tube500to prevent the reflector protective tube520from sliding. The provision of the aligner501as above enables alignment of the position of the main heater tube500inside the reflector protective tube520. Thus, for example, during transfer of the heater23, misalignment can be avoided between the reflector protective tube520and the main heater tube500. Note that, for example, the main heater tube500may be provided with the aligner501, provided that the aligner501can set the positional relationship between the main heater tube500and the reflector protective tube520.

For example, the main heater tube500is formed of quartz.

The reflector protective tube520includes a cylinder having an end, in its longitudinal direction (axial direction), provided with an opening522and the other end provided with a lid523. The reflector protective tube520has a cavity based on the cylinder and the lid523, and the space of the cavity is filled with a vacuum atmosphere or an inert-gas atmosphere. For a vacuum atmosphere in the space, for example, the air in the space is sucked through a suction/supply port521with which the lid523of the reflector protective tube520is provided. For an inert-gas atmosphere in the space, inert gas is supplied into the space through the suction/supply port521. In both cases, the space is kept depressurized. Note that, for example, the suction/supply port521also functions as a seal that prevents the inert gas from leaking outward from the space.

For example, a reflector530semicylindrical in shape is disposed in the space of the cylinder of the reflector protective tube520such that the reflector530is open toward the process chamber101aabove. A gap V is provided between the lid503of the main heater tube500and the lid523of the reflector protective tube520.

The reflector530is higher in thermal reflectivity than the bottom wall of the process container101disposed below the heater23.

For example, the reflector protective tube520is formed of quartz. For example, the reflector530is formed of molybdenum (MO) or platinum (Pt).

The insulating tube510cylindrical in shape is disposed inside the main heater tube500. For example, the insulating tube510is formed of a ceramic material, such as alumina (Al2O3), magnesia (MgO), zirconia (ZrO2), or aluminum titanate (Al2O3·TiO2), quartz, or SiC.

The heat emitter540serving as a heater wire is disposed inside the main heater tube500. The heat emitter540is wound spirally at predetermined pitches such that the insulating tube510is disposed inside the spiral. Between the main heater tube500and the insulating tube510, disposed is a power line (e.g., a power supply line)560connected to the heat emitter540through a sleeve580. In the inner space of the insulating tube510, disposed is a power line (e.g., a power output line)570connected to the heat emitter540through a sleeve590. The power lines560and570are disposed inside the support target504of the main heater tube500. For example, the current supplied from the power line560flows through the heat emitter540to cause the heat emitter540to generate heat.

Below the heater23, provided is the slider220that moves the wafer200(substrate mounting stage210). The reflector530is provided between the heat emitter540and the slider220. In addition, the reflector530is provided between the heat emitter540and the wafer lifter150. Such an arrangement enables prevention of heat transfer to the slider220and the wafer lifter150that require no heating below the reflector530. Such prevention of heat transfer as above is desirable because the slider220and the wafer lifter150each include, for example, a component and grease sensitive to heat.

Inside the insulating tube510, disposed is a thermocouple550that controls/monitors the temperature of the heat emitter540. The degree of energization of the heater23is feedback-controlled based on temperature information detected by the thermocouple550. Thus, the heater23enables retention of the temperature of the wafer200supported by the substrate mounting stage210at a predetermined temperature.

(3) Substrate Processing Process

Next, a process of forming a thin film onto a wafer200with the substrate processing apparatus100will be described as a partial process in a process of manufacturing a semiconductor device. Note that, in the following description, the controller110controls the operation of each constituent of the substrate processing apparatus100.

In the present embodiment, exemplified will be a case where HCDS gas is supplied as source gas through the source-gas supply line, N2gas is supplied as inert gas through each inert-gas supply line, and NH3gas is supplied as reactant gas through each reactant-gas supply line.

In a substrate loading step S101, a wafer200is loaded into the process container101. Specifically, with the gate valve103, which is provided at the wafer access port102with which the side wall101bof the process container101of the substrate processing apparatus100is provided, open, a wafer transferer (not illustrated) loads a wafer200into the process container101. In this case, the wafer lifter150rises to the position at which the wafer200is loaded (transferred), so that the wafer200is mounted on the upper ends of the lifting pins151. After that, the wafer lifter150falls, so that the wafer200is mounted on the substrate mounting face210aof the substrate mounting stage210. Then, the wafer transferer moves outward from the process container101, and the process container101is hermetically sealed internally due to occlusion of the wafer access port102based on shutting of the gate valve103.

After the wafer200loaded into the process container101is mounted on the substrate mounting face210a, in a pressure/temperature regulation step S102, the pressure and temperature in the process container101are regulated. In this case, for example, the heaters23are each supplied with power based on the value detected by the thermocouple550such that the wafer200has a desired processing temperature, such as a predetermined temperature in the range of 400 to 750° C. The wafer200is heated continuously at least until processing to the wafer200finishes.

After the pressure in the process container101reaches a desired processing pressure and the temperature of the wafer200reaches a desired processing temperature, a substrate processing step S103is performed. In the substrate processing step S103, the source-gas cartridge330and the reactant-gas cartridges340and350each supply processing gas. Specifically, the source-gas cartridge330supplies HCDS gas and N2gas, downward. The N2gas functions as a gas shield such that the HCDS gas is prevented from spreading below the reactant-gas cartridges340and350, that is, the HCDS gas is separated spatially from the other spaces. The reactant-gas cartridges340and350each supply NH3gas, downward. With a matcher (not illustrated) and a radio-frequency power supply (not illustrated), plasma is generated in the space on the lower side of each of the reactant-gas cartridges340and350.

In parallel with the supply of the gases, the gas exhauster operates to control the process chamber101ato be kept at a desired pressure. In response to stable space separation under the source-gas cartridge330, the slider220is driven to reciprocate the substrate mounting stage210, on which the wafer200is mounted, between the reactant-gas cartridge340, the source-gas cartridge330, and the reactant-gas cartridge350. Thus, the wafer200passes under the source-gas cartridge330and the reactant-gas cartridges340and350.

A clarified flow of the wafer200with the source gas and the reactant gas focused on is given in the following description. The surface of the wafer200is exposed to various types of gas in the following order. Such exposure is defined as one cycle and is repeated to form a desired film.

Under the source-gas cartridge330, the HCDS supplied on the wafer200is decomposed to form a Si-containing layer. Next, under the reactant-gas cartridge350, NH3in a plasma state is supplied to the Si-containing layer formed under the source-gas cartridge330to modify the Si-containing layer, resulting in formation of a SiN layer. Next, under the source-gas cartridge330, a Si-containing layer is formed on the SiN layer resulting from the modification under the reactant-gas cartridge350. Next, under the reactant-gas cartridge340, NH3plasma is supplied to the Si-containing layer formed under the source-gas cartridge330to modify the Si-containing layer, resulting in formation of a SiN layer. Thus, the processing described above is performed to the wafer200with the substrate mounting stage210reciprocating, so that a desired film can be formed.

After a SiN film having a predetermined composition and a predetermined thickness is formed on the wafer200, N2gas is supplied as purge gas from the inert-gas supply lines into the process container101and then is exhausted through the exhaust lines. Thus, a purge is made in the process container101, so that the residual gas and any reaction by-product in the process container101are removed from the process container101. After that, the atmosphere in the process container101is replaced with the inert gas (Inert gas replacement) and the pressure in the process container101is changed to a predetermined transfer pressure or is restored to the normal pressure (atmospheric pressure restoration).

In response to formation of a desired film in the substrate processing step S103, a substrate unloading step S104is performed. The substrate unloading step S104is reverse in procedure to the substrate loading step S101, in which the wafer transferer unloads the processed wafer200outward from the process container101.

A series of processing from the substrate loading step S101to the substrate unloading step S104described above is performed per wafer200serving as a processing target. That is, every time the wafer200is replaced with another wafer200, the series of processing S101to S104described above is performed a predetermined number of times. In response to completion of processing to all wafers200serving as processing targets, the substrate processing process finishes.

(4) Effects According to the Present Embodiment

According to the present embodiment, the following effects can be obtained.

(a) Each heater23includes the insulating tube510inside, in which the heat emitter540is provided with the power line570disposed in the inner space of the insulating tube510and with the power line560, different from the power line570, disposed between the main heater tube500and the insulating tube510and is wound spirally such that the insulating tube510is disposed inside the spiral. Thus, the heat emitter540can be prevented from being short-circuited. Thus, the heat emitter540being smaller in diameter in sectional view along the longitudinal direction of the heater23contributes to the heater23being smaller in size. As a result, a substrate processing apparatus smaller in size can be achieved. The heat emitter540connected to the power line570disposed in the inner space of the insulating tube510is disposed inside the insulating tube510, contributing to the heater23being smaller in size. As a result, a substrate processing apparatus smaller in size can be achieved.

(b) Since the insulating tube510is formed of an insulator, the heat emitter540can be wound around the insulating tube510, leading to a further reduction in the size of the heater23. As a result, a substrate processing apparatus smaller in size can be achieved.

(c) Since the reflector530is protected in the reflector protective tube520, the reflector530can be inhibited from being exposed to the open air, so that an improvement can be made in the efficiency of heating a wafer200.

(d) The space in which the reflector530is disposed in the reflector protective tube520is filled with a vacuum atmosphere or an inert-gas atmosphere, so that the reflector530can be inhibited from oxidizing. Thus, the reflector530can be inhibited from deteriorating over time, with an improvement in thermal reflectivity.

(e) Since the reflector530is formed of molybdenum or platinum, a high thermal reflectivity can be achieved. The reflector530is higher in thermal reflectivity than the bottom wall of the process container101disposed below the heater23, so that a further improvement can be made in the efficiency of heating a wafer200.

(f) The reflector530is open toward the process chamber101aand thus is capable of reflecting heat to the process chamber101aand preventing heat from moving below the process chamber101a, so that the wafer200disposed in the process chamber101acan be heated efficiently.

(g) The support target504having penetrated through the process container101is supported by the walls101e, so that damage can be prevented even when the main heater tube500thermally expands due to a flow of current through the heat emitter540. The power lines560and570are each disposed inside the support target504, so that the support target504can be supported by the walls101e.

(h) The gap V is provided between the lid503of the main heater tube500and the reflector protective tube520. Thus, even when the main heater tube500thermally expands due to a flow of current through the heat emitter540, the gap V absorbs the thermal expansion of the main heater tube500, so that the heater23can be prevented from being damaged.

(i) The support240that supports the heaters23is provided on the bottom (protrusion structure101f) of the process container101, so that the heaters23can be prevented from moving. Thus, the distance between the wafer200and each heater23can be kept constant.

(j) Since the longitudinal direction of each heater23is identical to the direction of movement of the substrate mounting stage210, each heater23is disposed in the longitudinal direction of the process container101, so that the space in the process container101can be effectively used.
