    • A bipolar transistor designed to support a substantially uniform current density in base and collector regions to prevent the characteristic early fall-off of bipolar transistor current gain, and to improve the forward safe operating area performance. The advantages of the present invention are achieved by optimally spacing the neighboring emitters in relation to base thickness and further by maintaining a symmetrical topology by the self-aligned formation of emitters and base contacts. The spacing distance between the neighboring emitters does not exceed the base thickness. As a result, the current density below each emitter island is substantially uniform and the transistor as a whole can conduct a higher total current. Moreover, the transistor inhibits formation of current filaments and hot spots because the electric field in the collector region is uniform.
    • 设计为支持基极和集电极区域中基本上均匀的电流密度的双极晶体管,以防止双极晶体管电流增益的特征性早期脱落,并改善正向安全工作区域性能。 本发明的优点是通过相对于基底厚度最佳间隔相邻的发射体并且进一步通过通过发射器和基极接触的自对准形成保持对称拓扑来实现。 相邻发射体之间的间隔距离不超过基底厚度。 结果,低于每个发射极岛的电流密度基本上是均匀的,并且整个晶体管可以传导更高的总电流。 此外,由于集电区域的电场均匀,所以晶体管抑制了电流丝和热点的形成。

    • The present invention discloses method for fabricating, and the structure of, a unique and novel bipolar transistor. The bipolar transistor of the present invention has a substantially uniform current density in base and collector regions. This uniform current density prevents the characteristic early fall-off of bipolar transistor current gain, and improves the forward safe operating area performance. As such, the bipolar transistor of the invention increases current gain at high collector currents, and expands the current and voltage region over which the device may safely operated. The advantages of the present invention are achieved by optimally spacing the neighboring emitters in relation to base thickness and further by maintaining a symmetrical topology by the self-aligned formation of emitters and base contacts. According to the invention, the emitters are optimally spaced so that the current emanating from an emitter would fill base and collector regions beneath and beside the emitter in a fashion to provide a uniform current distribution. As such, the entire base and collector regions below the center of a given emitter conduct the emitter majority carrier current in a substantially uniform manner. Therefore, the current density below each emitter island is substantially uniform and the transistor as a whole can conduct a higher total current. Furthermore, according to the invention, a uniform current flow is established before the carriers move out of the base region. The invented transistor inhibits formation of current filaments and hot spots because the electric field in the collector region is uniform.
    • 本发明公开了一种独特且新颖的双极晶体管的制造方法和结构。 本发明的双极晶体管在基极和集电极区域具有基本均匀的电流密度。 这种均匀的电流密度可防止双极晶体管电流增益的特征提前脱落,并提高正向安全工作区的性能。 因此,本发明的双极晶体管在高集电极电流下增加了电流增益,并扩展了器件可以安全工作的电流和电压区域。 本发明的优点是通过相对于基底厚度最佳间隔相邻的发射体并且进一步通过通过发射器和基极接触的自对准形成保持对称拓扑来实现。 根据本发明,发射器被最佳间隔开,使得从发射器发出的电流将以发射器下方和旁边的底部和集电极区域填充以提供均匀的电流分布。 因此,给定发射体中心下方的整个基极和集电极区域以基本均匀的方式传导发射极多数载流子电流。 因此,低于每个发射极岛的电流密度基本上是均匀的,并且整个晶体管可以传导更高的总电流。 此外,根据本发明,在载体移出基部区域之前,建立均匀的电流。 本发明的晶体管抑制了电流丝和热点的形成,因为集电区域的电场是均匀的。

    • Semiconductor diodes are diode connected cylindrical junction field effect devices having one diode terminal as the common connection between a top gate, a back gate and a first channel terminal of the cylindrical junction field effect devices. The second diode terminal of the semiconductor diodes being the second channel terminal of the diode connected cylindrical junction field effect devices. The method of processing the cylindrical junction field effect devices provide very short channels, shallow diffused regions and trench terminated junctions at the edges of the active device for low forward voltage turn-on and high reverse bias breakdown. The trench terminated junctions spread the breakdown energy over the entire active device region rather than just device edges.
