    • An apparatus including an electrostatic discharge (ESD) protection device is disclosed. The ESD protection device includes a semiconductor having a first region (270), a second region (120) laterally surrounded by the first region (270), and a third region (130) laterally surrounded by the second region (120) to form a bipolar device. The first region (270) is doped with a first impurity of a first conductivity type and is separated from the second region (120) which is doped with a second impurity of a second conductivity type opposite the first type. A dimensional constraint of the regions defines an operational threshold of the ESD protection device. In one example, the separation between the first region (270) and the second region (120) defines a trigger voltage to cause the ESD protection device to become conducting. In another example, a width (310) of the second region (120) controls a holding voltage of the ESD protection device.
    • 公开了一种包括静电放电(ESD)保护装置的装置。 ESD保护装置包括具有第一区域(270),由第一区域(270)横向包围的第二区域(120)的半导体和由第二区域(120)横向包围的第三区域(130),以形成第二区域 双极器件。 第一区域(270)掺杂有第一导电类型的第一杂质,并且与第二区域(120)分离,第二区域掺杂有与第一类型相反的第二导电类型的第二杂质。 这些区域的尺寸约束限定了ESD保护装置的操作阈值。 在一个示例中,第一区域(270)和第二区域(120)之间的间隔限定了触发电压,以使ESD保护装置导通。 在另一示例中,第二区域(120)的宽度(310)控制ESD保护装置的保持电压。
