    摘要: An electrostatic-discharge protection circuit having a low level of current leakage from a first power supply to a second power supply. An example protection circuit includes a timing element that electrically decouples the first and second power supplies. Another example protection circuit includes two transistors connected via a node that is electrically decoupled from the second power supply.

    摘要: Silicon is formed at selected locations on a silicon-on-insulator (SOI) substrate during fabrication of selected electronic components, including resistors, capacitors, and diodes. The silicon location is defined using a patterned, removable mask, and the silicon may be applied by deposition or growth and may take the form of polysilicon or crystalline silicon. Electrostatic discharge (ESD) characteristics of the SOI device is significantly improved by having a thick double layer of silicon in selected regions.

    摘要: ESD power clamp devices with vertical NPN devices are disclosed. The power clamp is formed on an N type substrate and includes an N channel field effect transistor (NFET). The source and drain regions of the NFET, a P type epitaxial region under the NFET, and the N type substrate constitutes two vertical NPN devices. As such, vertical interactions of electrons are enabled to avoid the disadvantages of traditional power clamps, e.g., minority carrier cross-talk.

    摘要: A method of testing a semiconductor wafer and a related structure. In various embodiments, a method includes: placing a probe on a first chip on the semiconductor wafer; testing a scribe line automatic built-in self-test (ABIST) for the first chip to search for a fault; progressively testing a subsequent scribe line ABIST for a subsequent chip on the semiconductor wafer in response to determining the ABIST for the first chip does not indicate the fault; moving the probe point to the subsequent chip and retesting the subsequent scribe line ABIST in response to determining the ABIST for the subsequent chip indicates a fault; and testing a further subsequent scribe line ABIST for a further subsequent chip on the semiconductor wafer in response to determining the retesting of the subsequent scribiline ABIST does not indicate a fault in the subsequent scribe line ABIST.

    摘要: A test system for testing a multilayer 3-dimensional integrated circuit (IC), where two separate layers of IC circuits are temporarily connected in order to achieve functionality, includes a chip under test with a first portion of the 3-dimensional IC, and a test probe chip with a second portion of the 3-dimensional IC and micro-electrical-mechanical system (MEMS) switches that selectively complete functional circuits between the first portion of the 3-dimensional IC in a first IC layer to circuits within the second portion of the 3-dimensional IC in a second IC layer. The MEMS switches include tungsten (W) cone contacts, which make the selective electrical contacts between circuits of the chip under test and the test probe chip and which are formed using a template of graded borophosphosilicate glass (BPSG).
