摘要： Back-end-of-line (BEOL) circuit structures and methods are provided for blocking externally-originating or internally-originating electromagnetic edge interference. One such BEOL circuit structure includes a semiconductor substrate supporting one or more integrated circuits, and multiple BEOL layers disposed over the semiconductor substrate. The multiple BEOL layers extend to an edge of the circuit structure and include at least one vertically-extending conductive pattern disposed adjacent to the edge of the circuit structure. The vertically-extending conductive pattern is defined, at least partially, by a plurality of elements disposed in the multiple BEOL layers. The plurality of elements are uniformly arrayed at the edge of the circuit structure in a first direction or a second direction throughout at least a portion thereof. The plurality of elements are sized and positioned in the first direction or the second direction to block electromagnetic interference of a particular wavelength from passing therethrough.

摘要： Circuits and methods are provided for facilitating transitioning of a digital circuit from backgate biased standby mode to active mode. The digital circuit includes a semiconductor substrate, multiple n-channel transistors disposed at least partially in one or more p-type wells in the semiconductor substrate, multiple p-channel transistors disposed at least partially in one or more n-type wells in the semiconductor substrate, and a backgate control circuit. The backgate control circuit is electrically coupled to the p-type well(s) and to the n-type well(s) to facilitate transitioning of the multiple n-channel transistors and the multiple p-channel transistors from backgate biased standby mode to active mode by automatically shunting charge from the n-type well(s) to the p-type well(s) until a well voltage threshold is reached indicative of a completed transition of the transistors from backgate biased standby mode to active mode.

摘要： Back end of line (BEOL) circuit structures and methods are provided for blocking externally-originating or internally-originating electromagnetic interference. One such BEOL circuit structure includes one or more semiconductor substrates supporting one or more integrated circuits, and one or more BEOL layers disposed over the semiconductor substrate(s). At least one BEOL layer includes a conductive pattern defined at least partially by a plurality of elements arrayed in a first direction and a second direction throughout at least a portion thereof. The plurality of elements are sized and positioned in at least one of the first and second directions to block electromagnetic interference of a particular wavelength from passing therethrough. In one implementation, a first conductive pattern of a first BEOL layer polarizes electromagnetic interference, and a second conductive pattern of a second BEOL layer blocks the polarized electromagnetic interference.

摘要： System and method are provided for continually monitoring reliability, or aging, of a digital system and for issuing a warning signal if digital system operation degrades past a specified threshold. The technique includes implementing a ring oscillator sensor in association with the digital system, wherein logic and/or device percent composition of the ring oscillator sensor mirrors percent composition thereof within the digital system. Counter logic is coupled to the ring oscillator sensor for converting outputted count signals to an oscillation frequency, and control logic is coupled to the counter logic for periodically evaluating oscillation frequency of the ring oscillator sensor and generating a warning signal indicative of reliability degradation if at least one of: (i) a measured or estimated oscillation frequency is below a warning threshold frequency; or (ii) a measured or estimated rate of change in a difference between measured oscillation frequencies exceeds an acceptable rate of change threshold.
