| 摘要 |
The invention relates to a semiconductor component having a coreless first transformer ( 71, 72 ) which comprises a first ( 71 ) and a second ( 72 ) planar winding, is arranged on a semiconductor body 9 and is surrounded in the lateral direction by a protective ring ( 1, 2 ). The protective ring ( 1, 2 ) has metal portions ( 1 a- 1 d), of which the top metal portion ( 1 a) is further apart of the first planar winding ( 71 ) in the lateral direction than the protective ring ( 1 b) which is second from top.
