Abstract

The invention discloses a temperature maintaining device for an integrated circuit chip, which comprises: an on-chip heating resistor, which is composed of a metal circuit of the chip; The temperature value controls the switch of the heating current of the on-chip heating resistor, and realizes the temperature control of the chip through the on-chip method. The invention also discloses a method for maintaining the temperature of the integrated circuit chip. The invention can maintain the temperature of the chip, especially when the chip is working in a low-temperature environment, the temperature of the chip can be kept at the temperature at which the chip works normally, so as to prevent the short-term failure or permanent failure of the integrated circuit on the chip; at the same time, the cost and function can be reduced. It can also greatly reduce device accuracy requirements, reduce reliability risks, increase the manufacturing process window, help extend chip life, and reduce error rates.

Description

technical field [0001] The invention relates to the field of semiconductor integrated circuits, in particular to a temperature maintaining device for integrated circuit chips. The invention also relates to a method for maintaining the temperature of the integrated circuit chip. Background technique [0002] Due to the changeable application environment of integrated circuit chips, when a low temperature environment occurs, the integrated circuit characteristics of the chip will shift. In extreme cases, there may even be a temporary failure or an irreversible operation triggered by an internal error, resulting in permanent failure, resulting in user losses. [0003] There are several known methods to maintain the temperature of the integrated circuit of the chip, such as the method of installing a heater outside the chip, the method of covering the entire circuit board with an insulating layer or the method of heating the liquid circulation system, etc., to help the chip mai...
