Abstract

PROBLEM TO BE SOLVED: To improve throughput in a sheet-type substrate processor by providing a cooling chamber which can receive numerous wafers. SOLUTION: Around a hexagonal wafer carry chamber including a wafer carrier 4, three processing chambers 1 for supplying oxidizing gas while heating a wafer 2 before processing to form an oxide film, a wafer cooling chamber 5 for receiving a high temperature wafer 21 formed with the oxide film which has completed with formation of the oxide film, and two cassette chambers 6 for putting the wafers 2, 21 to respective cassettes 7 are provided. The cooling chamber 5 has its wafer receiving part structured in multiple stages and is structured so that all of the wafers 21 processed in the three processing chambers 1 by a single process can be received. Therefore when the high temperature wafers 21 are successively taken out of the processing chambers 1 by the carrier 4, all of the wafers 21 can be cooled in the single cooling chamber 5, while the respective processing chambers 1 can manufacture next wafers 21 without being restricted by a wafer cooling process.

The VD (Chemical Vapor Deposition) process is an important process for manufacturing semiconductor devices. Up to now, the above-mentioned process has been mainly carried out in a so-called batch processing type semiconductor processing apparatus in which a large number of wafers are housed and processed in a reaction chamber because a large amount of processing can be performed and the process cost can be reduced.

In recent years, the size of the processing chamber (reaction chamber) has been increased in any of the above processes in order to cope with the ever-increasing wafer diameter (8 inches or more) and to improve the productivity by increasing the number of wafer charges. Is being promoted. However, it is very difficult to uniformly process all the wafers by the method of horizontally stacking the wafers in multiple stages and charging a large-diameter wafer in a large amount, and the method of arranging a large number of wafers in a plane has a small effect of increasing the size. It has become to.

The silicon epitaxial growth technique, in which a silicon single crystal thin film having the same orientation as the substrate is formed on the single crystal substrate wafer by a vapor phase chemical reaction, which is processed at a relatively high temperature as compared with the above-mentioned process, is also a semiconductor. This is the main process in device manufacturing. Conventionally, the epitaxial growth is performed by arranging the substrate wafers on a rotating disk-shaped heating table (susceptor) in a quartz reaction chamber in a plane and at a high temperature (up to 1000).
(C)) and the raw material silicon compound gas is radially supplied from a supply pipe in the center of the susceptor (pancake type epitaxial furnace). Further, there is also used an epitaxial growth furnace of a so-called barrel type in which the heating table has a pyramid shape and the wafers are arranged in a plane to increase the number of charges.

Each of the methods is a method in which wafers are arranged in a plane on a heating table, and the size increase is almost at the limit. Furthermore, the increase in the size of the susceptor causes an increase in heat capacity and a longer process time for raising and lowering temperature. Also from this point, the effect of improving productivity (the number of wafers produced per unit time: throughput) is reduced. Furthermore, it becomes difficult to supply the source gas uniformly to all areas of the large susceptor, and even if this non-uniformity is compensated by a method such as rotation, the epitaxial layer film thickness and resistivity of the wafer in all areas of the susceptor can be compensated. It is very difficult to make it uniform.

A single-wafer processing type semiconductor processing apparatus described in Japanese Patent Publication No. 9 and the like has been proposed. This method uses one substrate wafer,
Alternatively, since the two wafers are processed at a time, it is easy to secure the processing uniformity of the large diameter wafer.

However, in the single-wafer processing method, the number of processings in one batch is small and the throughput is theoretically small. For this reason, the process time is shortened, the operations such as wafer transfer are automated, the number of charged wafers is increased up to about 2 which can ensure the uniformity of heating and film thickness, and the processing chambers around one wafer transfer device are increased. Throughput is being increased by taking measures such as multi-setting in which a plurality of chambers are installed.

The process comprises a step of inserting a wafer into a processing chamber and heat-treating it in an oxidizing atmosphere, and a cooling step of cooling a high-temperature wafer that has been heat-treated to prevent deformation of a resin wafer cassette. ing. High throughput can be obtained by effectively utilizing the operation of one wafer transfer device (robot) (thick arrow in the figure) to complete the process of three chambers. In order to further increase the throughput in this process, it is important to shorten the heat treatment process and the cooling process time and shorten the overall process time. However, since the wafer is cooled in one chamber, the cooling process restricts the process flexibility of each chamber in addition to the operation of the wafer transfer device (robot), and eventually the process time of the entire device is shortened. It is difficult to achieve the objective of increasing throughput. Cooling chamber (cooling chamber) corresponding to each thermal oxidation chamber
The method of eliminating the restriction of the cooling process by the method of providing the above method cannot be said to be a promising measure because it causes an increase in the size and cost of the device.

FIG. 9 is an explanatory view of an example of a process sequence of a single wafer processing type epitaxial growth apparatus in which the growth chamber is multi-chambered. In the case of epitaxial growth, the process is a clean process by removing unnecessary silicon deposited in the reaction chamber after growth by vapor phase etching, in addition to the growth process of inserting the substrate wafer into the reaction chamber and forming the epitaxial layer and the cooling process of the wafer. The number of cleaning steps to be changed increases. Generally, one such as silicon epitaxial growth
In the case of a reaction at a high temperature of 000 ° C. or higher, the process time for cooling the wafer is long, and the influence of the cooling process on the process time of the entire apparatus is greater. An object of the present invention is to solve the above-mentioned problems and to provide a semiconductor processing method and a processing apparatus of a single-wafer processing system having a large throughput.

FIG. 6 shows the cooling characteristics of the wafers when the wafers are transferred to the cooling chamber 5 at equal time intervals two by three times. The wafers were stored in order from the top of the multi-stage wafer receiving section in the cooling chamber. It can be seen that the temperature of the lower wafer of the two initially transported wafers rises due to the influence of the hot wafers transported later, and the cooling time to the target temperature becomes longer. When the process time is shortened to increase the throughput, the influence of the high temperature wafer on the wafer cooling time becomes large.

FIG. 7 shows a cooling chamber 5 in which a partition plate 8 is provided for each wafer transferred at one time to reduce the influence of high-temperature wafers transferred later in order to solve such a problem. . By adopting a cooling chamber with such a structure,
Even when a large number of wafers are transferred in a short time, it is possible to solve the problem that the cooling time to the target temperature is long. A method of cooling the partition plate 8 with gas or water is a measure for making the effect more effective.
