Silicon controlled rectifier device with high-surge and high-stability triggering characteristics and preparation method of silicon controlled rectifier device
ActiveCN119630008AImprove surge capabilityImprove pressure resistanceSilicon-controlled rectifierMetal electrodes
The invention relates to the technical field of power devices, in particular to a silicon controlled rectifier device with a high-surge and high-stability triggering characteristic and a preparation method of the silicon controlled rectifier device. A protective layer is arranged between a front base region metal electrode and a front emitter region metal electrode, and a polycrystalline silicon resistance region is arranged in the protective layer and is respectively connected with electrodes on two sides for shunting. In order to solve the problem that a silicon controlled rectifier device cannot have high trigger current and high surge resistance at the same time, a parallel path is formed between positive electrodes through a polycrystalline silicon resistor region for shunting, so that the IG value of the trigger current is improved. According to the structure, the device can select a lightly doped base region and an emitter region with a wider area, so that the anti-surge capability and the voltage resistance are improved. Parameters of a polycrystalline silicon resistance region are limited, so that the polycrystalline silicon resistance region has a negative temperature coefficient, temperature compensation is formed for trigger current, and the problems that the trigger current of an existing silicon controlled rectifier changes along with temperature change, and IG current is reduced along with temperature rise are solved.
