A vacuum processing apparatus includes vacuum processing chambers for subjecting a sample to vacuum processing, a vacuum carriage, a switchable chamber, a cassette support for supporting a plurality of cassettes capable of housing samples, and a waiting cassette support for supporting a waiting cassette that differs from the cassettes supported on the cassette support and capable of having a number of samples. An atmospheric carriage enables carrying a sample among a given cassette of the plurality of cassettes or the waiting cassette. A controller effects control for carrying unprocessed and processed samples among the given cassette, the waiting cassette and the vacuum processing chamber, so that a mixture of both processed and unprocessed samples does not exist in the given cassette or the waiting cassette.

Vacuum processing apparatus

A vacuum processing apparatus and method in which the apparatus includes vacuum processing chambers for subjecting a sample to vacuum processing, a vacuum carriage, a switchable chamber, a cassette support for supporting a plurality of cassettes capable of housing samples, and a waiting cassette support for supporting a waiting cassette that differs from the cassettes supported on the cassette support and capable of having a number of samples. An atmospheric carriage enables carrying a sample among a given cassette of the plurality of cassettes or the waiting cassette. A controller effects control for carrying unprocessed and processed samples among the given cassette, the waiting cassette and the vacuum processing chamber, so that a mixture of both processed and unprocessed samples does not exist in the given cassette or the waiting cassette.

Vacuum processing apparatus and vacuum processing method

A vacuum processing apparatus and method includes at least one vacuum processing chamber, at least one carriage for carrying the sample from a given cassette into and out of the vacuum processing chamber. A controller performs carriage control for carrying the sample taken out of the given cassette into the vacuum processing chamber, and for carrying the processed sample out of the vacuum processing chamber. A waiting cassette support supports a waiting cassette in which an unprocessed sample from the given cassette or a processed sample from the given cassette after vacuum processing is placed so as to prevent the processed and unprocessed sample from being mixed with each other.

Vacuum processing method

The invention provides a semiconductor fabrication apparatus capable of preventing increase of carriage time of samples, deterioration of sample output, increase of footprint and increase of investment costs. The vacuum processing apparatus comprises a plurality of vacuum processing chambers for subjecting a sample to vacuum processing; a vacuum carriage for carrying the sample into and out of the vacuum processing chamber; a switchable chamber capable of being switched between atmosphere and vacuum for carrying the sample into and out of the vacuum processing chamber; a cassette support for supporting a plurality of cassettes and a controller for controlling carrying of the sample from a cassette through the switchable chambers, the vacuum carriage means into and out of the vacuum processing chamber. The vacuum processing chamber is equipped with an etching chamber and a critical dimension measurement chamber for critical dimension inspection of the sample.
