Filed: 1991-12-05
Abstract: PURPOSE:To accurately and inexpensively measure the temperature characteristic of a specific parameter in a short time by simultaneously measuring parameters having known and unknown temperature characteristics while the temperature of a semiconductor element is changed by irradiating the element with light. CONSTITUTION:Parameter having certain temperature characteristics are measured in advance about several pieces of samples. A semiconductor element 1 which is an object to be measured is placed on a table 2 made of a heat insulating material and heated by irradiating the element 1 with the light of an infrared laser, etc., introduced to the vicinity of a measuring instrument through a light guiding fiber 5 after condensation 4. Under such a condition, parameters having a known and unknown temperature characteristics are respectively and simultaneously measured with tracers 6 and 7 and 8 and 9. Then the then temperature is found from the parameter having the known temperature characteristic and the found temperature is used as the temperature of the parameter having the unknown temperature characteristic. By only heating the element 1 in such way, the thermal equilibrium state reaching time is shortened and the power consumption is reduced. In addition, since no header is required, the cost, labor, and time can be reduced and the measuring time can be shortened.
