Title: Wire bonding apparatus
Inventor: NAKAMURA NAOYA
IPC: H01L21/60
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To minimize the deformation of a wire by detecting the fact that the wire is bonded to the surface of a work, setting a predetermined delay time based on the detected signal, and starting the oscillation of ultrasonic wave based on the set signal. SOLUTION: When bonding is performed by using a chip, which is die-bonded on a ceramic substrate with solder, as a work 1 and by applying pressure to a wire 8 while lowering a tool 2 onto the work 1, a force detector 5 using a piezoelectric detecting element or the like is embedded in a work bench 4 to thereby detect a force applied to the work 1 by the tool 2. A signal from the detector 5 is amplified by a high-sensitivity amplifier, and the amplified signal is further given a predetermined time delay by triggering a delay circuit 6. An ultrasonic oscillator 7 is thereafter activated. As a result of this arrangement, the deformation of the wire 8 before applying ultrasonic wave can be minimized, thereby improving the bonding quality such as the lifetime of bonds.

Title: Planar motor device and projection aligner
Inventor: TANAKA KEIICHI
IPC: H02K41/02
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a planar motor device for suppressing heat effects to a surrounding environment. SOLUTION: When a current is supplied to an armature coil 34 that faces a magnetic pole unit 40, a wafer stage WST is driven along a traveling surface 32a by electromagnetic force. As a result, each armature coil 34 where a current is supplied generates heat. The armature coil 34 is arranged along the traveling surface in a base 32, and a first fluid path 62, where a first fluid flows in a laminar flow state is provided at the traveling surface side of the armature coil 34, and a second fluid path 64 where a second fluid flows in a laminar flow state is provided at the opposite side to the traveling surface. Therefore, a temperature boundary layer is formed in the flow of the first fluid for effectively preventing the heat of the armature coil 34 from being transferred to the traveling surface.  At the same time, the heat transfer rate between the second fluid and a stator yoke 58 increases, thus efficiently eliminating the heat of the armature coil 34 due to the second fluid.
