A transfer chamber for a substrate processing tool includes a main body having side walls adapted to couple to at least one processing chamber and at least one load lock chamber. The main body houses at least a portion of a robot adapted to transport a substrate between the processing chamber and the load lock chamber. A lid couples to and seals a top of the main body of the transfer chamber. The transfer chamber also has a domed bottom adapted to couple to and to seal a bottom portion of the main body of the transfer chamber.

An improved prober for an electronic devices test system is provided. The prober is “configurable,” meaning that it can be adapted for different device layouts and substrate sizes. The prober generally includes a frame, at least one prober bar having a first end and a second end, a frame connection mechanism that allows for ready relocation of the prober bar to the frame at selected points along the frame, and a plurality of electrical contact pins along the prober bar for placing selected electronic devices in electrical communication with a system controller during testing. In one embodiment, the prober is be used to test devices such as thin film transistors on a glass substrate. Typically, the glass substrate is square, and the frame is also square. In this way, “x” and “y” axes are defined by the frame. The electrical pins may be movable along the axial length of the prober bars, or may be selectively pushed down to contact selected contact pads on the substrate.

A robot device that either translationally or rotationally aligns an object with a slot. For translational alignment, the robot device comprises a position sensor positioned in close proximity to the slot. The translational position sensor determines the position of the object by moving the object parallel to the slot until it actuates the position sensor. For rotational alignment, two position sensors are provided that determine the relative angle between the object and a portion of the robot device and the object.

The invention provides an apparatus and method for performing a process on a substrate. At least two types of structures may be used to provide a flow path for a substrate so that the substrate may be moved from one processing or loading position to another. The first is a conveyor. The second is a track. The flow path may be a closed continuous loop. Each processing island has a valve for introduction and extraction of the substrate into and out of an interior of the island. The processing island may include load locks, and may include in conjunction therewith an inspection station, a CVD chamber, a PECVD chamber, a PVD chamber, a post-anneal chamber, a cleaning chamber, a descumming chamber, an etch chamber, or a combination of such chambers.

A method and apparatus for recording data on a magnetooptical recording medium finds an optimum laser beam intensities for recording. The method and apparatus do not cause a low level P.sub.L setting to become excessively low and poor overwriting of data during overwrite recording. Recording can be accomplished changing low level and high level laser beam intensities, while holding the ratio of the low level and high level laser beam intensities constant. Data can be reproduced and evaluated. When the optimum laser beam intensities have not been determined, the intensity ratio of the low level and high level intensities can be altered. After data has been is reproduced and evaluated, the process can be repeated, until the optimum laser beam intensities are obtained. Further, recording can be based on temperature of the recording medium and surroundings to obtain optimum laser beam intensities.

In magnetooptic recording, compensation is provided for changes in temperature up and down characteristics for heating and cooling processes of a recording medium due to the rise and fall of a laser beam effected in dependence on the relative velocity of the laser beam and the recording medium. The advantages of the Z-CAV system, i.e., a high density recording and an enhanced access performance are realized and the reliability for performing a high density recording is also improved in the case of the CAV system. The relation between the relative velocity of the laser beam and the medium or the linear velocity of the medium and the thermal time constant of the medium is clarified and the thermal time constant .tau. at the current linear velocity is obtained. Information to be recorded is converted into binary signals and the laser beam intensity modulated in accordance with the binary signals is projected on the mangetooptic recording medium thereby recording the information. Thermal time constant information relating to the temperature variations of the magnetooptic recording medium due to the projection of the laser beam is preliminarily recorded on the magnetooptic recording medium. A clock frequency f is controlled in such a manner that a ratio T/.tau. between a reciprocal T of the clock frequency f and the thermal time constant .tau. of the medium is always maintained constant. The starting and end positions of each mark are formed with a high degree of accuracy.

This invention relates to an optical recording method and apparatus, in which the intensity of a laser beam to be radiated onto an optical recording medium is raised from an intensity P.sub.pre for maintaining a pre-heat state in which the temperature of the medium surface becomes a predetermined temperature, to P.sub.W1 higher than P.sub.pre, the intensity is reduced to an intensity P.sub.LT lower than P.sub.W1 after P.sub.W1 is maintained for a time T.sub.W1, and thereafter, the laser beam is intensity-modulated between P.sub.LT and an intensity P.sub.W2 higher than P.sub.LT so as to form a mark on the optical recording medium. When at least one of P.sub.W2, P.sub.LT, and a time T.sub.W2 for maintaining P.sub.W2 is controlled, the medium temperature, after an elapse of T.sub.W1, at the peak temperature position or the spot center position of the laser beam radiated onto the medium surface is equal to the medium temperature after an elapse of T.sub.W2.

A plasma welding method has successive steps including pre-heating of members to be welded, tack welding of the members for tentatively fixing these members, keyhole welding for completely welding the members to each other, and finish padding. These steps are automatically conducted by a single plasma welding apparatus operative in accordance with a programmed sequence including data concerning the optimum conditions of operation in each step in relation to the conditions such as sizes and materials of the members to be welded. The apparatus has a welding torch, a welding head on which the welding torch is mounted for rotation, a controller adapted for storing the optimum welding conditions for successive steps of the welding process in relation to the conditions of the members to be welded, a power supply system for transmitting welding current and welding speed signal to the welding head in accordance with a command provided by the controller, and a gas supply system for supplying a plasma gas at a rate determined in accordance with a command from the controller.
摘要:
A piping travelling apparatus having a plurality of continuous treads driven by motors through transmission gearing. The continuous treads are mounted to a frame and spaced apart a predetermined distance peripherally of the inner wall surface of the piping. At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.
