An arrangement for handling wafer-shaped objects is to ensure a high degree of positioning accuracy with increased productivity, freely selectable transport paths, and low mechanical expenditure under SMIF conditions. The arrangement has at least one indexing device for supplying and accepting the objects at a supplying and accepting location situated in a handling plane and at least one transporting device for transporting the wafer-shaped objects between the supplying and accepting location and a work station. The work station, together with at least one other work station, is arranged substantially coaxially to a central point through which passes a rotational axis of a changer. The arrangement is applicable in the manufacture of integrated circuits.

A device for coupling containers at a loading and unloading port with a horizontally displaceable platform for receiving the container has the object of increasing protection against faulty operation and faulty loading in a simple manner while guaranteeing technical cleanroom requirements and without limiting the clear space of the platform. An arrangement for detecting the presence of a container and for distinguishing between containers with different contents is provided for an expectancy area above the platform. The device is used for the loading and unloading at machining or processing stations of objects that are to be transported in a container, especially objects in the fabrication process for integrated circuits.

An indexer for magazine shelves of a magazine and wafer-shaped objects contained therein has the object of ensuring accurate access in any desired and predeterminable magazine plane, also for magazines which are provided with an opening on only one removing and charging side, by means of an all-purpose indexing, wherein it is possible to differentiate between various standardized magazine and wafer formats. The magazine shelves and the wafer-shaped objects are detected by an optoelectronic sensor arrangement, at least a portion of which is designed as a distance measuring system. The indexer is applicable in the manufacture of integrated circuits, in particular, for handling wafer-shaped objects in the form of semiconductors and masks.

A device for handling disk-shaped objects in a handling plane of a local clean room has the object of ensuring process steps preceding or following the processing and inspection of the disk-shaped objects under the conditions of a local clean room with the use of SMIF boxes. The handling plane (H--H) is in a fixed constructional relationship with a reference plane (E--E) of at least one device comprising the magazine seat as a component part, which device serves to index the shelves of magazines and disk-shaped objects contained therein and is arranged above an intermediate base dividing the clean room into two partial spaces located one above the other, in which an air flow component of an air flow is directed from the partial space above the intermediate base into the partial space below the intermediate base. The device can be used in the manufacture of integrated circuits, particularly for handling tasks.

The invention relates to an improvement for a wafer mounting table particularly for use in photolithographic apparatus for processing wafers comprising a compact mounting block made of glass-ceramics which has two neighboring back supports limiting two sides of a top face of said mounting block. The top face is provided with at least three studs for supporting a wafer to be processed. The sides of the back-supports facing away from said top face are provided with an elongated horizontally extending silvered area each, which is in opposition to a laser path measuring system each. The laser beams of said laser path measuring system define a plane which coincides with a projection plane of a projection lens being provided in opposition to a wafer mounted on said studs. Means are provided for substantially eliminating departures of the silvered areas from a straight plane. Further means are provided which enable a quick adaption of the laser mount for wafer charges having different thicknesses or diameters.

In a device for manipulating an object for loading and unloading a clean room, the problem is to reduce the hardware expense for adjustment devices and for air conditioning while maintaining ergonomic benefits and to further improve the clean room conditions in the device. The device contains a stationary outer part (3) of a housing (2) as well as an inner part (4) that can extend telescopically from it and a receptacle element (11) in the roof area of the inner part (4). For the telescopic extension of the inner part and for the lowering of the receptacle element into the inner part, a common guide rail (16) and a common drive (20) are provided. The receptacle element connected to the drive engages with a driver of the inner part for the telescopic extension of the inner part by vertical upward movement and after reaching an access level (E2, E2), at which the inner part is secured, it can be lowered in the inner part. The inner part is flushed with an air flow coming from the clean room in the region of each level. The device is used for loading and unloading of clean rooms with objects that are transported in a container.

A device and method for the sensing of wafer-shaped objects and shelves in a container is disclosed. The device and method function to increase the reliability of detection in containers which are open on one side as well as in containers which are open on two sides, and to detect whether a shelf is occupied by more than one object, to detect oblique positions of the objects along several shelves and the position of the shelves themselves independent from dimensional tolerances without impeding the handling of either the wafer-shaped objects or the container and without interfering with clean room conditions. Radiation from a radiation source which is reflected at the front sides of the objects and at the shelves is directed to optoelectronic sensor elements for recording an image by an imaging optical device. The recording of every image is adapted to the reflectance ratios at the front sides which contribute to the imaging. The device and method is applicable in the manufacture of integrated circuits.

A device for indexing magazine compartments of a magazine and wafer-shaped objects contained therein to ensure precise access of the removing and charging device in any given predetermined plane of the magazine regardless of dimensional tolerances. An optoelectronic sensor having a transmitter and receiver emits a bundle of measurement rays to detect the position of the wafer-shaped objects as well as the position of the magazine compartments relative to a reference plane whose location is rigidly defined by design with respect to a first handling plane for removing and charging. The magazine is adjustable vertically in a measurable manner for removal and charging by a magazine seat via a magazine lift. The device is applicable in the manufacture of integrated circuits, in particular for handling wafer-shaped objects.

A secure (e.g., HTTPS) connection is established between a client and a server. Communication over the connection may utilize an application (e.g., a Web browser) that is not part of the client's trusted computing base. A password is sent from the client to the server over the connection such that the clear text password is unavailable to the application. For example, the password can be encrypted and inserted directly into the HTTPS stream from the client's trusted computing base.

For a device for the detection of substrates stacked at an opening of a wall element, there existed the problem of constructing the detection device in such a way that the detection of the position of the substrates can be performed more flexibly with respect to the course of measurement and the measuring method employed and a defined approach of a sensor system to the semiconductor substrate to be detected is ensured in a definite position of measurement with a lowered risk of particle generation.A transmitting and receiving device (11) consists of a vertical drive mechanism (10) mounted on the wall element (1) and a sensor head (13) that can be adjusted between a lower and an upper position by means of the vertical drive mechanism (10), said sensor head being arranged so as to pivot on the vertical drive mechanism (10) in order to pivot into the opening (4).The device finds application, in particular, in the semiconductor industry for recording the state of occupancy of cassettes or containers with substrates, such as semiconductor wafers, flat-screen displays, or masks.
