In an embodiment, a connectivity test is performed on vias between a first layer and a second layer to determine a via diameter and a via offset that are used to evaluate misalignment.

In this way, the via diameter, the via offset, or the alignment rotation are used to evaluate the tiered semiconductor structure, such as during a stacked CMOS process, for misalignment.

Abstract: The present invention provides a radio field intensity measurement device having a display portion with improved visibility, in the case of measuring a weak radiowave from a long distance. In the radio field intensity measurement device, a battery is provided as a power source for power supply and the battery is charged by a received radiowave. When a potential of a signal obtained from the received radiowave is higher than an output potential of the battery, the power is stored in the battery. On the other hand, when the potential of the signal obtained from the received radiowave is lower than the output potential of the battery, power produced by the battery is used as power to drive the radio field intensity measurement device. As an element to display the radio field intensity, a thermochromic element or an electrochromic element is used.

Abstract: A method of operating an electronic device during test mode operation of a duplicated voltage monitor includes sensing a functional supply voltage with a voltage monitor, deasserting an output of the voltage monitor if the functional supply voltage is exceeds a threshold, and asserting output of the voltage monitor if the functional supply voltage falls below the threshold.
