Abstract
An electronic device has a semiconductor chip and a passive component, whose electrical values can be varied. The semiconductor chip is electrically conductively connected to a rewiring structure that, together with the semiconductor chip and with the passive component, is enclosed by a housing made of plastic. A method for producing the electronic device is also described.
Claims9
An electronic device, comprising:
- at least one semiconductor chip;
- at least one trimmable passive component electrically conductively connected to said semiconductor chip and having electrical values that can be varied;
- a rewiring structure electrically conductively connected to said semiconductor chip;
- and
- a housing made of plastic enclosing said rewiring structure, said semiconductor chip and said trimmable passive component, said housing totally enclosing said semiconductor chip and enclosing said trimmable passive component to an extent that a surface of said trimmable passive component remains accessible for a trimming operation after incorporation of the electronic device in an electronic circuit.
