摘要:
A semiconductor wafer-processing apparatus has a plurality of support members provided respectively for the processing units of a processing apparatus, and designed for supporting wafer receptacles each containing semiconductor wafers, and receptacle-inserting/extracting mechanism for inserting a wafer receptacle from the support members into the processing units, and for extracting the wafer receptacle from the processing units back to the support members. Receptacle-transporting mechanism is provided, operated independently of the receptacle inserting/extracting mechanism, for transporting the wafer receptacle between each support member and a predetermined position.

The present invention relates to an apparatus for transferring a plurality of semiconductor wafers from their cassettes to a boat. This apparatus comprises a support body on which the cassettes and the boat are mounted, a lifter for lifting wafers from the cassettes, a handling device for carrying the wafers and transferring them to the boat, and a plurality fans for introducing dust created by the handling device into the support body and removing it outside the support body.

A wafer transferring method for transferring wafers between a cassette and a boat having grooves to hold the wafers, comprises the steps of providing an identification mechanism for positional alignment on the boat in advance, detecting the identification mechanism, and aligning the boat to a predetermined position based on a detection result and transferring the wafers from the cassette to the boat. A wafer transferring apparatus comprises a loading device for extracting wafers from a cassette and transferring the wafers onto a boat, a detection device for detecting an identification section provided on the boat in order to identify a wafer transferring position on the boat, and a control device for acquiring the wafer transferring position on the boat based on a detection result attained from the detection device and controlling a mutual position between the boat and the cassette to come to a predetermined position.

A pitch changing device of the present invention includes a lift mechanism for unloading a plurality of wafers arranged in a cassette at predetermined pitches from the cassette while the pitches are kept unchanged, and a chuck mechanism for holding the unloaded wafers while the pitches are kept unchanged. The chuck mechanism includes moving pieces mounted to be movable in an arrangement direction of the wafers, for respectively supporting the wafers, elastic members mounted in the movable pieces to be expandible/contractible in the arrangement direction of the wafers, and a driving mechanism for expanding/contracting the elastic members. When the elastic members expand/contract by the driving mechanism, the pitches of the wafers are changed while the wafers are held. The lift mechanism includes a handler for variably moving wafer stands in the arrangement direction of the wafers, and changes the pitches while the wafers are lifted.

A treatment apparatus used in manufacturing processes for semiconductor devices and the like, in which substrates are treated by means of a reaction gas. An inner tube, which is coaxially disposed in a reaction tube, defines a reaction region surrounding the substrates to be treated. The inner tube has a number of perforations in its wall, by means of which the inside and outside of the reaction region communicate with each other. During reaction treatment, the reaction gas is supplied to the reaction region, while a cleaning gas is supplied to the region outside the reaction region. Both these gases are discharged through a common exhaust pipe. The flows of the reaction gas and the cleaning gas are controlled so that the pressure inside the reaction region is higher than the pressure outside the region. As the cleaning gas is supplied, production and adhesion of reaction compound particles on the inner surface of the reaction tube is prevented.

The apparatus comprises a first holding member having a flat surface which is brought into contact with the nonprocess surface of the semiconductor wafer, a pair of second holding members having inclined surfaces which are spaced apart from said flat surface by a predetermined distance, and cooperate with the flat surface to receive the arcuated edge of the semiconductor wafer. The second holding members are spaced apart from each other in a direction perpendicular to a semiconductor wafer insertion direction. The inclined surfaces being inclined such that a distance between the inclined surfaces and the flat surface is decreased in the semiconductor wafer insertion direction, thereby clamping the arcuated edge portions of the semiconductor wafer.

An apparatus for detecting an array of wafers comprises a reference information generator for generating reference information from the reference condition in which wafers are partly inserted correctly in all grooves formed in side plates of a first wafer carrier, a window setting device for setting wafer-detecting windows at those positions where the wafers are arranged on a second wafer carrier, in accordance with the reference information supplied from said reference information generator, a photosensor for detecting the wafers arranged on the second wafer carrier and generating information representing the presence of the wafers on the second wafer carrier, a signal generator for generating signals from the information generated by the photosensor, and a position detector for collating the signals supplied from the signal generator with said wafer detecting windows, to detect the shape of that portion of any signal that corresponds to a wafer window, and to determine the position of the wafer from the shape of said portion of the signal.

A heat-treating apparatus includes a process tube accommodating an object to be heat-treated therein, and a plurality of independent heaters including at least three heaters arranged at both end portions and the central portion of a side wall of the process tube, so as to surround the process tube and, the heating temperatures of the individual heaters being freely adjustable. In this heat-treating apparatus, no direct heat transfer is caused between the heaters, so that the heating temperature of the heater at each end portion of the process tube can be adjusted to a high value, without entailing such an uneven temperature distribution as is caused in the case of a conventional heat-treating apparatus. Thus, uniform temperature distribution can be attained in an area covering the same range for the conventional apparatus, even though the heaters at both end portions are reduced in length.

An apparatus for transferring wafers comprises a turntable for orienting a plurality of wafers which are loaded in a cassette, a lifting mechanism for lifting the wafers away from the cassette, a plurality of opening/closing chuck mechanisms, and a slide movement mechanism for conveying the wafers which are held by the opening/closing mechanism onto a boat. The cassette on the turntable is turned selectively through an angle of 180.degree. and wafers are lifted by the link mechanism all at a time and selectively held by the opening/closing chuck mechanism. The wafers thus held are conveyed to a location of a boat where they are loaded onto the boat in a face-to-face relation.
