  • Patent number: 7537673
    Abstract: Disclosed herein is a plasma processing apparatus, which generates plasma within a vacuum chamber to process semiconductor substrates using the plasma. The apparatus comprises a substrate mounting table, an outer lifting bar, and a baffle. The outer lifting bar comprises a driving shaft, and a substrate supporting member coupled perpendicular to an upper end of the driving shaft. The baffle comprises a baffle plate coupled to the upper end of the driving shaft, and a shielding portion coupled to a lower surface of the baffle plate. The substrate supporting member is a foldable substrate supporting member. The baffle and the substrate supporting member are driven up and down at the same time by the driving shaft. As a result, it is possible to protect the substrate supporting member from plasma, and to prevent interference between the baffle and the outer lifting bar during operation of the plasma processing apparatus.

  • Patent number: 6867323
    Abstract: Improved methods for generating a ā€”Cā€”Cā€” bond by cross-coupling of a transferable group with an acceptor group. The transferable group is a substituent of an organosilicon nucleophile and the acceptor group is provided as an organic electrophile. The reaction is catalyzed by a Group 10 transition metal complex (e.g., Ni, Pt or Pd), particularly by a palladium complex. Certain methods of this invention use improved organosilicon nucleophiles which are readily prepared, can give high product yields and exhibit high stereoselectivity. Methods of this invention employ activating ions such as halides, hydroxide, hydride and silyloxides. In specific embodiments, organosilicon nucleophilic reagents of this invention include siloxanes, particularly cyclic siloxanes. The combination of the cross-coupling reactions of this invention with ring-closing metathesis, hydrosilylation and intramolecular hydrosilylation reactions provide useful synthetic strategies that have wide application.

  • Publication number: 20040123952
    Abstract: An FPD fabricating apparatus according to the present invention comprises two chambers of a process chamber 130 and a transfer chamber 120. The substrate 140 is mounted on and transferred by one of two carrier plates 150a and 150b, each of which have a forked shape. The carrier plate lift pins 160b are raised up and fallen down while avoiding contact with the forked prongs of the robot arm 122a, so that the carrier plates 150a and 150b can be raised up and fallen down. The substrate lift pins 160a which are raised up and fallen down while avoiding contact with all the forked prongs of the robot arm 122a and the carrier plates 150a and 150b, so that only the substrate 140 mounted on the carrier plates 150a and 150b can be raised up and fallen down. According to the present invention, a load-lock chamber for transferring a substrate and a transfer chamber is incorporated into a single transfer chamber, so that space of the apparatus can be remarkably reduced and cost of the apparatus can be reduced.
