Referring to Figure 3.2 and assuming a three-dimensional (3D) density of states and the Maxwell-Boltzmann statistics for the carrier density, the electron and hole densities are described by

The backup command offers a few more options than Management Studio, and using the backup command directly is useful for assembling SQL Server Agent jobs by hand, rather than with the Maintenance Plan Back Up Database Task. Without all the options and frills, the most basic backup command is as follows:

to a speci c IC substrate and to study its attenuation as it moves along the substrate path. Point A is an interference source and point B is the sensor for receiving the interference signal moving along the substrate path from A to B. The source at point A looks like an n-channel MOSFET on the left hand side, which will be connected to the network analyzer port 1. The network analyzer at port 1 provides an RF signal to this IC die sample as an interference source. The sensor at point B is a P+ buried pad with a metallic contact on the right hand side, which will be connected to port 2 of the network analyzer and will function as an interference sensor. If the substrate is not a perfect insulator in the interference frequency, the interference signal from port 1 of the network analyzer will move along the substrate path from point A to B and be received by the sensor. The attenuation of the interference signal from A to B can be found from the reading of S21 in the network analyzer. If the substrate were an ideal insulator, the attenuation would be in nite and the interference would completely disappear. Usually, the substrate is not an ideal insulator and the interference will appear with a certain amount of attenuation. As a matter of fact, the attenuation from source A to sensor B is a measure of isolation between the sensor and the source. Quantitatively, the value of S21 depends on the distance D between the sensor and source, the size of the source contact area and the sensor contact area d, and other parameters of the IC die, such as the thickness of the substrate, the characteristics of the substrate, and so on. As an example, Figure 16.4 shows a measured

behavior. A quantity that allows immediate interpretation is the occurrence rate of fading dips this occurrence rate is known as the Level Crossing Rate (LCR). Obviously, it depends on which level we are considering (i.e., how a fading dip is de ned): falling below a level that is 30 dB below the mean happens more rarely than falling 3 dB below this mean. As the admissible depth of fading dips depends on the mean eld strength, as well as on the considered system, we want to derive the LCR for arbitrary levels (i.e., depth of fading dips). Providing a mathematical formulation, the LCR is de ned as the expected value of the rate at which the received eld strength crosses a certain level r in the positive direction. This can also be written as: NR (r) =
