Abstract
이 발명은 과전압, 과전류, 고온도 등에 의한 반도체 디바이스(device)의 파괴를 방지할 수 있도록 보호기능이 내장되어 있는 스카트 디스크리트의 구조 및 제조방법에 관한 것이다.The present invention relates to a structure and a manufacturing method of a scart disc with a built-in protection function to prevent the destruction of a semiconductor device due to overvoltage, overcurrent, high temperature and the like.
일반적으로 전류 제한회로는 주 반도체 장치, 감지장치, 감지저항, 보호 트랜지스터 등으로 구성되는데, 이렇게 구성된 종래의 스마트 디스크리트(smart discrete)는 주 반도체 장치와 감지장치 사이에 기생 트랜지스터와 기생저항이 발생하는 문제점이 있었고, 또한 이러한 문제점을 해결한 또다른 종래 기술은 추가적인 공정이 필요하여 제조공정과 구조가 복잡해진다는 문제점이 있었다.In general, the current limiting circuit is composed of a main semiconductor device, a sensing device, a sensing resistor, a protection transistor, and the like. In the conventional smart discrete structure, a parasitic transistor and a parasitic resistance are generated between the main semiconductor device and the sensing device. There was a problem, and another prior art that solves this problem has a problem that the manufacturing process and structure is complicated because additional processes are required.
따라서, 이 발명에서는 이오 같은 문제점을 해결하기 위하여 감지장치의 기능과 보호 트랜지스터의 기능이 복합된 셀 구조, 또는 독립된 보호 트랜지스터의 기능을 갖는 구조를 주 반도체 장치와 감지장치 사이에 형성한 전류 제한회로를 구성하여 집적도를 향상시키고 기생 트랜지스터와 기생저항의 발생을 방지하여 과전류에 대하여 정확히 동작하므로써 반도체 장치를 보호할 수 있는 스마트 디스크리트를 구성하였다.Therefore, in the present invention, in order to solve the problem, the current limiting circuit is formed between the main semiconductor device and the sensing device with a cell structure in which the function of the sensing device and the protection transistor are combined, or the structure having the function of an independent protection transistor. The smart discrete can protect the semiconductor devices by improving the integration density and preventing the occurrence of parasitic transistors and parasitic resistances so as to operate correctly against overcurrent.
