    摘要: Systems and methods are described for fabricating semiconductor gate oxides of different thicknesses. Two methods for forming gate oxides of different thicknesses in conjunction with local oxidation of silicon (LOCOS) are disclosed. Similarly, two methods for forming gate oxides of different thicknesses in conjunction with shallow trench isolation (STI) are disclosed. Techniques that use two poly-silicon sub-layers of substantially equal thickness and techniques that use two poly-silicon sub-layers of substantially unequal thickness are described for both LOCOS and STI. The systems and methods provide advantages because gate uniformity and quality are improved, the processes and resulting devices are cleaner, and there is less degradation of carrier mobility.

    摘要: A substrate transport apparatus is provided for stably transporting a substrate and sensing a receiving state of the substrate. The substrate transport apparatus includes a grip member for gripping a substrate placed on the pocket part of the hand when a hand returns to a groove position from a pickup position. The grip member may include a pusher and an elastic member. The pusher has a curved section contacting the edge of a substrate and is mounted on the base to move in the same direction as the at least one hand, and the elastic member supplies an elastic force for enabling the pusher to laterally press the edge of the substrate.

    摘要: The present invention is directed to a spin chuck for use in a process, such as a cleaning process and an etching process, performed while rotating a substrate. The spin chuck includes a spin head on which a substrate is placed, a driving part configured to rotate the spin head, and a fix bracket installed on the spin head and having a contact surface that is in contact with a flat surface of a flat zone of the substrate at a position corresponding to the flat zone to prevent a vortex caused by the flat zone. Since the fix bracket has the same shape as the flat zone of the substrate, an air current unbalance resulting from the flat zone is suppressed to uniformly inject etchants to a rear surface of the substrate.
