Abstract
Abstract The object of a device for coupling loading and unloading devices with semiconductor machines is to couple devices required for the use of SMIF technology with semiconductor processing machines in which subsequent integration of SMIF technology is not possible, wherein the charging to be carried out after coupling is highly flexible and capable of managing increasing dimensions of semiconductor wafers. An adjustable receiving element for the loading and unloading device is provided inside a movable enclosure, this receiving element being displaceable between at least two planes situated one above the other, one plane serving for charging the loading and unloading device and every other plane being used for the charging of the semiconductor machine carried out by the loading and unloading device. The enclosure has aligning and holding elements for fastening to a coupling element which is aligned with the semiconductor processing machine. The device enables retrofitting of semiconductor processing planes with SMIF technology while taking into account ergonomic requirements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
A device for coupling loading and unloading devices with semiconductor processing machines, comprising: an adjustable receiving element for a loading and unloading device which is provided inside a movable enclosure; said receiving element being displaceable between at least two planes situated one above the other, one plane serving for charging the loading and unloading device and every other plane being used for the charging of the semiconductor machine carded out by the loading and unloading device; wherein said enclosure has aligning and holding elements for fastening to a coupling element which is aligned with the semiconductor processing machine; wherein said enclosure includes a stationary outer part and an extendable inner part which encloses the receiving element together with the loading and unloading device; and wherein said inner part can be moved in and out in a telescoping manner together with the receiving element and the loading and unloading device for the purpose of adjusting the receiving element between planes located one above the other.
Claim 2
