Latest Patents
Yamashita's latest patents include a semiconductor test system designed for efficiently testing a semiconductor device with a phase lock loop (PLL) circuit. This innovative system features a first clock and waveform generator that supplies a clock signal to the PLL circuit at the start of the first pattern block. Additionally, it includes a second clock and waveform generator that provides pattern data to the device under test (DUT) during each pattern block. The system ensures that the clock signal is continuously provided to the PLL circuit until the end of the last pattern block, while resetting the pattern data between blocks.
Another notable patent is the semiconductor IC tester, which is capable of conducting a double-speed test for an IC device under test. This tester allows for the application of test patterns and comparison of resulting signals in both halves of the test cycle without sacrificing the number of test pins. The double-speed mode effectively doubles the generating speed of test patterns, enhancing the testing process for IC devices.
