  • Patent number: 6568580
    Abstract: Wafers are previously positioned so that the wafer orientation flat is oriented in a particular direction. A transporting means then moves and places the previously positioned wafer on a bonding stage where bumps are formed on the wafer by means of a bonding head. The transporting means has a sensor for detecting the position of the orientation flat of a wafer on the bonding stage from a position above the bonding stage, thereby avoiding the adverse effects of heat from the bonding stage during orientation flat detection.

  • Patent number: 6484252
    Abstract: A microcomputer includes an instruction decoder and a program counter. The instruction decoder decodes fetched instructions and outputs a control signal ordering execution of the fetched instruction. The control signal from the instruction decoder includes a component controlling fetch cycles which triggers a fetch cycle at the beginning of each instruction cycle to fetch the operand for the instruction currently being executed and midway through each instruction cycle to fetch the OP code for the next instruction. The program counter is responsive to the triggering of each fetch cycle to increment its counter value so as to keep the counter value consistent with the address being accessed in each fetch cycle.

  • Patent number: 6392202
    Abstract: An object of the present invention is to provide a bump-bonding heating apparatus, a bump bonding method and a bump forming apparatus which do not involve large-sized apparatus configuration and which are easy to handle, and a semiconductor wafer in which bumps are formed by using the bump bonding method. The bump-bonding heating apparatus has a wafer turning member, a turning unit and a wafer heating unit. The turning member is turned by the turning unit without turning the wafer heating unit, whereby a semiconductor wafer mounted on the turning member is turned. Like this, since the wafer heating unit is not turned, the apparatus configuration can be made compact. Since the turning member is turned directly by the turning unit, the turning angle of the semiconductor wafer can be implemented with higher precision as compared with the conventional gas floating type turning method.

  • Publication number: 20010052114
    Abstract: A data processing apparatus which downloads a corrective program into its RAM during initial program loading, performs by its CPU interrupt processing in response to an interrupt request signal output from a debugging circuit when a program address coincides with a predetermined bug address, executes the debugged program, then reads program codes from the memory address next to the buggy part of a program to continue the processing after the interrupt processing. By executing the debugged program stored in the RAM as an interrupt processing routine instead of executing the buggy part of the program stored in the ROM, the buggy program is replaced by the bug-free corrected program and therefore the bug can be avoided.

  • Patent number: 6229874
    Abstract: A base member obtained by cutting a cylindrical body having a center axial line at a maximum asymmetric angle &agr;0 with respect to a plane orthogonal to the center axial line of cylindrical body is prepared. Next, the thus obtained ellipsoidal asymmetric cut surface of the base member is shaped along a peripheral surface of an imaginary cylindrical body having a radius R0, into an asymmetric cut curved-surface. Then, a monochromator Si crystal is bonded to the asymmetric cut curved-surface of the base member. Both the asymmetric angle and the radius of curvature for a desired wavelength within a wide wavelength range can be simultaneously tuned only by the &phgr;-axis rotation.
