The Development of High Voltage/High Speed SOI LIGBT
【摘要】 采用数值模拟分析了双降场层SOI-LIGBT击穿电压与SOI层厚度和隔离SiO2层厚度的关系,分析了阳极短路面积比对器件正向压降、关断时间和正向转折电压的影响,并利用硅直接键合(SDB)技术研制出580V的阳极短路SOI-LIGBT,关断时间为250ns
【Abstract】 The relationship between breakdown voltage of SOI LIGBTs using double field reduction layers and thickness of SOI layers and isolation SiO 2 layers is analyzed with numerical simulation Effects of anode shorted area ratio on the on state voltage,turn off time and forward snap back voltage of the device are examined Using silicon direct bonding(SDB) technology,anode shorted SOI LIGBTs have been manufactured,which have a breakdown voltage of 580 V and turn off time of 250 ns
