  • Publication number: 20200227402
    Abstract: In a general aspect, a semiconductor device can include a heavily-doped substrate of a first conductivity type, a lightly-doped epitaxial layer of a second conductivity type disposed on the heavily-doped substrate, and a heavily-doped epitaxial layer of the second conductivity type disposed on the lightly-doped epitaxial layer. The heavily-doped epitaxial layer can have a doping concentration that is greater than a doping concentration of the lightly-doped epitaxial layer. At least a portion of the heavily-doped substrate can be included in a first terminal of a Zener diode, and at least a portion of the lightly-doped epitaxial layer and at least a portion of the heavily-doped epitaxial layer can be included in a second terminal of the Zener diode. The semiconductor device can further include a termination trench that extends through the heavily-doped epitaxial layer and the lightly-doped epitaxial layer, and terminates in the heavily-doped substrate.

  • Patent number: 10217733
    Abstract: An ultra-low capacitance ESD protection device with an ultra-fast response time and a low turn-on voltage, and a high holding current. The device may include: a heavily-doped p-type substrate; a lightly-doped n-type epitaxial layer with a heavily-doped n-type buried layer; and a semiconductor-controlled rectifier (SCR) structure within the epitaxial layer. The SCR structure includes, between a ground terminal and a pad terminal: a shallow P+ region within a moderately-doped n-type well to form an emitter-base junction of a trigger transistor; a shallow N+ region within a moderately-doped p-type well to form an emitter-base junction of a latching transistor, and a PN junction coupled to either of the shallow regions as a forward-biased series diode. To reduce capacitance, the n-type and p-type wells are separated by a lightly-doped portion of the epitaxial layer having a small lateral dimension for enhanced switching speed.
