  • Publication number: 20070023986
    Abstract: A holder for fabricating an organic light emitting display comprises: a holder main body; and a plurality of supporters provided on opposite sides of the holder main body; wherein each supporter has a ‘?’-shape and comprises a side wall having a predetermined height, and a supporting plate bent from the side wall. The supporting plate is formed with a plurality of stepped parts to support a substrate, a film tray and a mask, to hold the substrate, the film tray and the mask while the substrate, the film tray and the mask are being transported, and to prevent a pattern from being distorted, thereby transporting and processing a substrate, a film tray and a mask in a single chamber at the same time.

  • Publication number: 20060269671
    Abstract: The present invention provides a catalytic enhanced chemical vapor deposition (CVD) apparatus capable of maximizing efficiency of gas use to 80% or more, and obtaining a uniform thin film by efficiently arranging filaments mounted on a shower head of the catalytic enhanced CVD apparatus, thereby uniformly decomposing a deposition source gas. The present invention also provides a method for fabricating an organic electroluminescent device with an inorganic film formed through the catalytic enhanced CVD apparatus.

  • Publication number: 20060228827
    Abstract: Methods of fabricating an organic light emitting device using plasma and/or thermal decomposition are provided. An insulating layer is formed by reacting first and second radicals. The first radical is formed by passing a first gas through a plasma generating region and a heating body, and the second radical is formed by passing a second gas through the heating body. The methods improve the characteristics of the resulting insulating layer and increase the use efficiency of the source gas by substantially decomposing the source gas. The insulating layer can be a passivation layer formed on an organic light emitting device. The methods use plasma apparatuses such as an inductively coupled plasma chemical vapor deposition (ICP-CVD) apparatuses or plasma enhanced chemical vapor deposition (PECVD) apparatuses.

  • Publication number: 20060121816
    Abstract: A method of manufacturing an organic light emitting device by using a facing target sputtering apparatus is provided. The method includes forming a first electrode on a substrate; forming an organic film on the first electrode; and forming a second electrode on the organic film by using a facing target sputtering apparatus. Accordingly, an electrode film is formed on the organic light emitting device at a low temperature without deterioration of the electrode film due to plasma, it is possible to improve light emitting efficiency and electro-optical characteristics of the organic light emitting device.

  • Patent number: 6857090
    Abstract: A system and method automatically analyzes and manages loss factor data of test processes in which a great number of IC devices are tested as a lot with a number of testers. The lot contains a predetermined number of identical IC devices, and the lot test process is performed sequentially according to a predetermined number of test cycles. The system include a means for verifying test results for each of the test cycles and for determining whether or not a re-test is to be performed and an IC device loading/unloading means for loading IC devices to be tested and contained in the lot to a test head and for unloading the tested IC devices from the test head by sorting the tested IC devices according to the test results.
