    摘要: The value of an unknown test temperature is measured by heating a test wafer (58) to the unknown temperature, measuring the surface electrical resistivity of the test wafer (58), and determining the value of the unknown temperature from the measured surface electrical resistivity. The test wafer (58) is prepared by providing an initial wafer (50), first ion implanting the initial wafer (50) with a first dose of an ionic species, and annealing the ion implanted initial wafer (50) at an annealing temperature. The preparation is completed by second ion implanting the annealed wafer with a second dose of the same ionic species as used in the first dose to form a test wafer, the second dose being lower than the first dose.
