ELECTRONIC COMPONENT

摘要

The invention relates to an electronic component (1) comprising a substrate layer (2), a buffer layer (3) positioned on the latter, a cover layer (8) that is applied over the buffer layer (3) and at least two channel layers (7a, 7b) located between the buffer layer (3) and the cover layer (8). According to the invention, each channel layer (7a, 7b) consists of piezo-polar material and at least one intermediate layer (6) is provided between each pair of adjacent channel layers (7a, 7b). At least the area surrounding one of the boundary surfaces between the first channel layer (7b, 7c) and/or the lower channel layer (7a) and one of the layers (3, 4a, 5a, 4b, 5b, 8) that is adjacent to the upper or lower channel layer (7a, 7b, 7c, ...) is doped, forming a compensation layer (4a, 4b), in such a way that the piezo charges occurring on each doped boundary surface are partially or fully compensated.
