Latest Patents
Koumyoji's latest patents include a semiconductor device and a test method for the same. This innovative multi-bus semiconductor device allows for a probing test that performs DC tests for individual pads of a device. It effectively manages an adequate number of devices for simultaneous measurement based on the scheme of input/output pad number compressive testing. The device incorporates switch elements connected between input/output pads and a testing line, enabling the selection of pads in arbitrary combinations for testing. This is achieved while deactivating the input/output buffers of the pads under test to block their internal current paths. The corresponding switch elements are activated to connect the off-probe pads to the probe pad, allowing for the measurement of leak current with the tester.
