    • A junction barrier Schottky (JBS) rectifier device and a method of making the device are described. The device comprises an epitaxially grown first n-type drift layer and p-type regions forming p+-n junctions and self-plana'zing epitaxially over-grown second n-type drift regions between and, optionally, on top of the p-type regions. The device may include an edge termination structure such as an exposed or buried p+-n guard ring, a regrown or implanted junction termination extension (JTE) region, or a ''deep'' mesa etched down to the substrate. The Schottky contact to the second n-type drift region and the ohmic contact to the p-type region together serve as an anode. The cathode can be formed by ohmic contact to the n-type region on the backside of the wafer. The devices can be used in monolithic digital, analog, and microwave integrated circuits.
    • 描述了结屏障肖特基(JBS)整流器件及制造器件的方法。 该器件包括外延生长的第一n型漂移层和形成p + -n结的p型区域和自平面外延生长的第二n型漂移区之间,并且任选地在p型上 区域。 该装置可以包括边缘终端结构,例如暴露或掩埋的p + -n保护环,再生长或注入的连接终止延伸(JTE)区域或向下蚀刻到衬底的“深”台面。 与第二n型漂移区的肖特基接触和与p型区的欧姆接触一起用作阳极。 阴极可以通过欧姆接触形成在晶片背面的n型区域上。 该器件可用于单片数字,模拟和微波集成电路。
