  • Patent number: 11961770
    Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

  • Publication number: 20100308754
    Abstract: Organic light emitting diode (OLED) devices are one of the most promising alternatives to liquid crystal displays (LCDs) for flat panel display (FPD) applications. The OLED technique is based on organic semiconductors used either as hole- or electron transporting materials or as an emitter. Working on common problems of performance and life time in OLED preparation, improved charge transport molecules and polymers such as triarylamine- and poly(para-phenylene)-have been developed. Some useful materials include: (1) cyclic triarylamine-derivatives possessing enhanced glass transition temperatures; (2) triarylamine based low molecular mass hole-transport molecules and hole-transport polymers with pendant oxetane groups for processing out of solution and subsequent cross-linking; and (3) fluorenyl-segmented poly(para-phenylene)s with defined electrochemical properties. Provided is a polymer precursor that is useful as a hole transport polymer in OLED and other organic electronic devices.
