Mit den handelsüblichen Probenhalterungen können weder Materialbruchstücke noch Proben mit ungewöhnlichen Geo metrien und Größen in standardisierten - auch automati sierten - Prozeßabläufen bearbeitet werden. Entweder müssen derartige Proben separat behandelt werden oder sie werden verworfen. Beides ist kostenaufwendig.With the commercially available sample holders, neither Material fragments still samples with unusual geo metrics and sizes in standardized - also automatic Processed processes are processed. Either have to such samples are treated separately or will be discarded. Both are expensive.
Es ist die Aufgabe der Erfindung, ausgehend von den han delsüblichen Halterungen und unter deren Nutzung, solche Veränderungen vorzusehen, daß Proben mit beliebig abwei chender Geometrie eingesetzt werden können.It is the object of the invention, starting from the han usual mounts and using them, such Provide changes that samples with any deviations appropriate geometry can be used.
Die Lösung dieser Aufgabe gelingt mit den im Kennzeichen des Anspruchs 1 dargelegten Mitteln.This problem is solved with the in the license plate of claim 1.
Allgemeingültige vorteilhafte weitere Ausbildungsmöglich keiten sind den Unteransprüchen entnehmbar.Generally valid advantageous further training opportunities can be found in the subclaims.
Die verwendeten Paßstücke und Haltestäbe sind in ihren Einzelteilen untereinander kompatibel und in kommerziell erhältliche Halterungen einsetzbar.The adapters and support rods used are in theirs Individual parts compatible with each other and in commercial available brackets can be used.
So können Proben mit unüblichen Maßen oder Bruchstücke jeden technologischen Prozeß - auch automatisierte - durch laufen ohne apparativen oder personellen Mehraufwand. Wichtig ist dies u. a. in der Industrie, beispielsweise der Halbleiterindustrie. This allows samples with unusual dimensions or fragments every technological process - even automated - through run without additional equipment or personnel. This is important. a. in industry, for example the Semiconductor industry.
Dadurch können teure Verluste durch Materialbruch, bei spielsweise von InP, LiNb03, vermieden werden.This can result in expensive losses due to material breakdown by InP, LiNb03, for example.
Die Konstruktion und die Herstellung der Spezialhalterung ist einfach. Das Material für die Spezialhalterung kann je nach Bedarf gewählt werden (PTFE, andere Polymere, Quarz glas, Metall, etc.).The design and manufacture of the special bracket is simple. The material for the special bracket can vary can be selected as required (PTFE, other polymers, quartz glass, metal, etc.).
Die Spezialhalterung kann in handelsüblichen Halterungen, z. B. für Prozeßautomaten in der Halbleiterindustrie, ein gesetzt werden. Deshalb können auch die Proben mit unge wöhnlichen Geometrien und Größen die standardisierten bzw. automatisierten Prozesse durchlaufen.The special holder can be used in standard holders, e.g. B. for process machines in the semiconductor industry be set. Therefore, the samples can also be usual geometries and sizes the standardized or go through automated processes.
Die Wirkungsweise und die näheren Ausbildungsmöglichkeiten sind nachfolgend an Ausführungsbeispielen näher erläutert.
