Latest Patents

Among his latest patents is a "Method and apparatus for die testing." This invention features a device tester that includes a probe card and a substrate coupled to the probe card. The substrate is designed with multiple layers for routing signals, and an integrated circuit is connected to it. This integrated circuit is capable of transmitting an input signal from a testing apparatus to a device under test via the substrate to a signal probe. The signal probe can receive a test signal from the device under test in response to the input signal. The integrated circuit amplifies this test signal and sends the amplified version back to the testing apparatus.

Another significant patent is the "Delay test circuitry." This programmable delay test circuitry is designed for testing a circuit under test on an integrated circuit. It utilizes logic circuitry to output an error signal when the delay time from the circuit under test exceeds a programmed characteristic time. The circuitry may also include a logic gate that generates a pulse with a width equal to the delay of the delay circuitry. Additionally, it features a programmable load that can be set to a specific characteristic time, asserting an error signal when the delay time surpasses the test circuitry's characteristic time.
