DIODE DEVICE COMPRISING CATHODE BUFFER LAYER

摘要

The present invention relates to a diode comprising: a positive electrode plate; an insulator layer on the positive electrode plate; a negative electrode buffer layer on the insulator layer; and a negative electrode on the negative electrode buffer layer. The diode having the negative electrode buffer layer does not limit the thickness of an insulator and an electrode of a bottom; and selectively controls unidirectional and bidirectional rectification according to the thickness of the insulator. Mass production is possible due to easy manufacturing. Provided are an improved feature and an excellent feature of the diode.
