Abstract

It is an object to operate a semiconductor device within a desirable operating temperature range in a normal operation or a test operation. A semiconductor device 100 comprises a temperature sensor portion 110 for detecting a temperature to output a heat generation instruction when the temperature is equal to or lower than T degree and to output a heat generation stop instruction when the temperature is equal to or higher than T' degree, and a heat generating portion 120 for performing / stopping the generation of heat in accordance with the heat generation instruction / heat generation stop instruction from the temperature sensor 110. Even if a temperature around the semiconductor device is low, the semiconductor device 100 can be maintained to be a certain temperature or more without an influence thereof. When the temperature around the semiconductor device rises, moreover, heat is not generated. Consequently, it is possible to prevent a malfunction from being caused at a high or low temperature.

Description

technical field [0001] The present invention relates to a semiconductor device. Background technique [0002] In recent years, with the development of semiconductor technology, semiconductors have been used in various electronic devices. For example, electronic equipment using semiconductors is also suitable for use in various environments such as the signal processing section of portable communication terminals, the electronic control section of automobile engines, the image processing section of artificial satellites, and the image sensing section of medical equipment. [0003] Semiconductors are designed to operate normally under the conditions of the ambient temperature in which they will be used. By designing semiconductors to operate properly over the widest possible temperature range, it is possible to use electronic devices in a variety of temperature conditions. For example, home video cameras configured with semiconductors that operate normally at -40°C to 120°C ...
