IPC: H01L21/66
Filed: 1990-01-12
Abstract: PURPOSE:To increase the simulating speed by fixing the logical value of a net forming a logic circuit and simulating a trouble generating state via a simulation chip. CONSTITUTION:A simulation chip 1 simulates the state of a logic circuit to be simulated with its self-run based on the response secured to plural RAMs 2 which store the data on the constitution of a function logic circuit 13 which performs the simulation, the data on a test pattern used for testing the working of the circuit 13, and the simulation result. As a result, the simulation is attained with the self-run (arithmetic processing carried out within the chip 1) without answering a general-purpose computer during the simulation. In such a constitution, the logic circuit is simulated and the trouble detecting rate of the test pattern is decided at a high speed.

Filed: 1993-01-18
Abstract: PURPOSE:To suck and move an IC chip with a collet without causing damages or cracks in the surface protective film of the IC chip by providing an air inlet port at the side surface of the collet. CONSTITUTION:When a collet 2 is driven with a driving device and a protruding part 4b of the side surface having an air inlet port 4a comes into contact with the side surface of an IC chip 3, a side surface 3a of the IC chip 3 is sucked with a sucking device through the air inlet port 4a and attracted to the air inlet port 4a. When the side surface 3a of the IC chip 3 is attracted to the collet 2, the driving device drives the collet 2 again, and the IC chip 3 is moved to a semiconductor-chip attaching part such as a die pad of a lead frame. Thus, the occurrences of damages or cracks on the protective film of the semiconductor chip during the movement of the semiconductor chip caused by the collet can be prevented.

Abstract: PURPOSE:To eliminate the release of a capping state even if an impact or a vibration is applied by locking a lever for performing capping and pumping operations in the capping state in the period until the pressure in a sub-tank is returned to the original state by the first and second locking levers. CONSTITUTION:Even if a lever 20 is released after pumping, a pawl 31 is engaged with the bent 33b of the first locking lever 33, and cannot move upward from the capping position. Since other pawl 32 is contacted with the straight part 34c of the second locking lever 34 at this time, it is not engaged with the inside of an extension 40 since it is contacted with the straight part 34c of the second locking lever 34, but the lever 34 is inclined by deflecting a twisted coil spring 41. This state is continued until the pressure in the sub-tank in pumping 5 is returned to the original. The pawl 32 is engaged within the recess 40b of the second lever 34 in the capping state, and held by the returning force of the spring.

Filed: 1984-01-18
Abstract: PURPOSE:To generate an FFT address capable of rearray an output data in the FFT operation by inverting the logic of the LSB of the FFT address counter in the final bus of the FFT. CONSTITUTION:During a path 4 which is the final bus of the FFT operation, outputs S0, S1 and S2 of a shift register 2 go to ''1'', ''1'' and ''1'' respectively, selectors 5a-5d select outputs of C1, C2 and C3 of a counter 1 and the output of an exclusive OR4, and they are outputted. Since the serial output E0 of the shift resister 2 is the logic ''1'' at this time, the output of the exclusive OR4 goes to C0 if a control input V0 is the logic ''1''. If the V0 is the logic ''0'', the output of the exclusive OR4 goes to C0. The FFT output is rearranged when V0=''1''.
