    Abstract: Integrated circuits that include bi-directional protection diode structures are disclosed. In one example, an integrated circuit includes a test circuit portion for testing the functionality of the integrated circuit during or after fabrication of the integrated circuit. The test circuit portion includes first, second, and third diode structures and a resistor structure. The first and third diode structures are in parallel with one another and in series with the resistor, and the resistor and the first and third diode structures are in series with the second diode structure. The first and third diode structures are configured for current flow in a first direction and the second diode structure is configured for current flow in a second direction that is opposite the first direction.

    Abstract: Disclosed is a method of manufacturing integrated circuit (IC) chips, which includes forming routing structure(s) that facilitate process limiting yield (PLY) testing of test devices. A routing structure includes an array of link-up regions and a set of metal pads surrounding that array. Each link-up region includes two sections, each having two nodes electrically connected to the terminals of a corresponding two-terminal test device. During PLY testing with a probe card, electrical connections between the test devices and the metal pads through the link-up regions allow each test device to be tested individually. Optionally, additional routing structures with the same footprint are formed down the line and stacked one above the other. These additional routing structures are used for PLY testing with the same probe card. Optionally, dummy pads are formed between stacked routing structures to improve robustness. Also disclosed is a semiconductor structure formed according to this method.
