Filed: 2011-04-06
Abstract: PROBLEM TO BE SOLVED: To solve such problems that ohmic contact properties are unable to secure even though a junction body is used as a temperature sensor by using a technique to diffuse metal components onto ceramics to join each other, and especially when the temperature sensor is used in the wide temperature range of -50°C to 1050°C, measuring accuracy cannot be increased and peeling and cracking are easy to occur because of bad heat resistance.SOLUTION: The temperature sensor element is composed of a thermistor which is constituted by Si-based ceramics, and a pair of metal electrodes joined onto the surface of the thermistor. The metal electrode contains Cr and a metallic element α having a diffusion coefficient of silica higher than that of Cr. On a boundary surface of the thermistor and the metal electrode, a diffusion layer is formed in which silicide of the metallic element α exists in a crystal grain boundary of the Si-based ceramics. By this diffusion layer, heat resistance and junction reliability are secured, and the temperature sensor capable of detecting a highly accurate temperature can be obtained, especially also in the temperature range of -50°C to 1050°C.

Title: Method for evaluating semiconductor device
Inventor: KAMATA KOICHIRO
IPC: H01L29/786
Filed: 2011-05-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating reliability of a transistor in a simple manner.SOLUTION: Instead of a bias temperature-stress test (BT test), a simple test having a correlation with the BT test is performed. Specifically, a gate current value of an n-channel transistor in which a channel region is formed by an oxide semiconductor is measured in a state where a voltage lower than the threshold voltage of the transistor is applied between a gate and a source, and a potential higher than that applied to the gate is applied to a drain. Compared to the BT test, the evaluation of the gate current value can be performed in a simpler manner, as the measurement of the gate current value takes short time, for example. That is, reliability of a semiconductor device having the transistor can be simply evaluated.
