Abstract

The invention discloses a high-temperature testing device and method for an integrated chip, and the method comprises the steps: inputting a heating current to an idle pin of a to-be-tested chip, so as to improve the testing temperature of the to-be-tested chip; determining whether the test temperature of the to-be-tested chip reaches a target temperature; and when the test temperature of the to-be-tested chip reaches the target temperature, performing parameter or performance test on the to-be-tested chip by using the test machine. The high-temperature test of the integrated chip can be realized on a general test board at normal temperature, the requirement on equipment is low, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a high-temperature testing device and testing method for an integrated chip. Background technique [0002] With the enhancement of integrated chip functions and the continuous expansion of integration scale, chip testing has become more and more difficult, and the testing cost is often higher than the design cost. The testing cost has become an important part of the product development cost. The length of testing time It also directly affects the time to market of products and thus affects economic benefits. [0003] The parameters and performance of integrated chips exhibit different characteristics under different temperature conditions, mainly including normal temperature (25°C) characteristics, low temperature (below 25°C) characteristics and high temperature (higher than 25°C) characteristics. In the research and development, factory testing and application development of i...
