    Abstract: PROBLEM TO BE SOLVED: To provide equipment for positioning a wafer inside an exposure device.
    SOLUTION: The equipment comprises a holder 124 constituted to hold a wafer 126 (having a plurality of positioning mark), a rough positioning device, and a fine positioning device having more accuracy than the rough positioning device. The fine positioning device has a plurality of photodetectors 122. Each photodetector is arranged in order to detect a corresponding positioning mark on the wafer. A positioning processor 120 is connected to the plurality of photodetector and holder, and controls them. The plurality of photodetectors are controlled by the positioning processor, and detect the plurality of positioning mark in parallel operation. Further, the positioning processor processes signals from the plurality of photodetector in parallel operation at a time.

    Abstract: A method of forming a wiring structure for an integrated circuit includes the steps of forming a plurality of features (16) in a layer of dielectric material (13), and forming spacers (20) on sidewalls (16s) of the features. Conductors (25) are then formed in the features, being separated from the sidewalls by the spacers. The spacers are then removed, forming air gaps (40) at the sidewalls so that the conductors are separated from the sidewalls by the air gaps. Dielectric layers (42, 12) above and below the conductors may be low-k dielectrics having a dielectric constant less than that of the dielectric between the conductors. A cross-section of each of the conductors (25) has a bottom in contact with a low-k dielectric layer (12), a top in contact with another low-k dielectric (42), and sides in contact only with the air gaps (40). The air gaps serve to reduce the intralevel capacitance.
