A spacer layer is formed on a single-crystal substrate and an epitaxially grown layer composed of a group III-V compound semiconductor layer containing a nitride or the like is further formed on the spacer layer. The epitaxially grown layer is adhered to a recipient substrate. The back surface of the single-crystal substrate is irradiated with a light beam such as a laser beam or a bright line spectrum from a mercury vapor lamp such that the epitaxially grown layer and the single-crystal substrate are separated from each other.

The disclosed invention relates to a calibration method, system and apparatus for a multimetals continuous emissions monitor system (hereinafter "multimetals CEMS"). More specifically, this invention relates to a calibration scheme for continuous monitoring of mercury emissions from stationary sources by plasma emission spectrometry. A source of mercury vapor, preferably a mercury permeation tube, entrains mercury vapor into a constant flow of carrier air. The carrier air mixes with a constant flow of diluent air in an aerosol mixer. The mixer is operably coupled to the analyzer. A gaseous mixture having a calibration mercury concentration flows from the mixer into the analyzer at a constant rate. A graph having coordinates of analyzer signal intensity and mercury concentration is used to plot the calibration scheme. A first signal intensity generated by the analyzer in response to the calibration mercury concentration is used for the first plot on the graph. A second signal intensity generated by the analyzer in response to a blank having zero mercury concentration is used as the second plot on the graph. A linear relationship between the analyzer signal intensity and the mercury concentration on the graph is established from the first plot and the second plot. The slope intercept and slope are used to create a mathematical relationship between the analyzer signal intensity and the mercury concentration. This enables the analyzer to be calibrated by inserting a known mercury concentration into the analyzer and adjusting the signal intensity to conform to the signal intensity calculated from the graph or mathematical relationship.
