Expert Solution

the detailed steps and diagrams for the n mosfet fabrication process is given above .

in first step si3n4 is added and it is in p substrate.
in next the si3n4 is removed by chemical vapour deposition process(CVD) and a poly-si gate is added and it becomes n substrate here .
in third an extra deposited insulator is added .
last step a Al metal is added to the deposited insulator .
these are the 4 steps for the fabrication process of N-mosfet device.

Can you please type out the answer A random sample of n = 12 individuals is selected from a population with µ = 70, and a treatment is administered to each individual in the sample. After treatment, the sample mean is found to be M = 74.5 with SS = 297. Is there evidence to indicate that your sample is significantly different from the population using α=.05? calculate the effect size for your results.

Engineering system of type k-out-of-n is operational if at least k out of n components are operational. Otherwise, the system fails. Suppose that a k-out-of-n system consists of n identical and independent elements for which the lifetime has Weibull distribution with parameters r and λ. More precisely, if T is a lifetime of a component, P(T ≥ t) = e−λtr, t ≥ 0. Time t is in units of months, and consequently, rate parameter λ is in units (month)−1. Parameter...
