Semiconductor bridge coupled with one or more thermistors and the method of the same

A method of a detonator for an explosive material, comprising:

• providing a semiconductor bridge to couple with the explosive material, the semiconductor bridge including:
• a polysilicon resistor and one or more thermistors disposed in parallel next to the polysilicon resistor;
• coupling the polysilicon resistor with the explosive material, wherein a current flow throughout the polysilicon resistor generates heat, the heat is accumulated over time and ignite the explosive material when the heat exceeds a threshold for the polysilicon resistor, the polysilicon resistor and the at least two thermistors are precisely arranged in parallel across two spaced conductive pads and on top of an insulating layer and isolated from each other and wherein the polysilicon resistor, the at least two thermistors and the two spaced conductive pads form a parallel resistor circuit;
• and
• dropping resistance of each of the thermistors drastically when the heat exceeds a threshold for the thermistors, wherein the current flow is diverted from the polysilicon resistor to the thermistors so as to reduce the heat being generated in the polysilicon resistor, the threshold for the thermistors is lower than the threshold for the polysilicon resistor.
