Claim:
1. A circuit device, comprising: a base plate having a first outer side and a second outer side opposite said first outer side; a first substrate disposed on said first outer side of said base plate; a second substrate disposed on said second outer side of said base plate; at least one electrical connection element electrically connecting said first substrate and said second substrate; at least one electronic component disposed on or in said first substrate; at least one electronic component disposed on or in said second substrate; a mold package molded around said first and second substrates and said electronic components arranged thereon; said mold package, in a region of said first substrate, being formed of a first material having a thermal expansion coefficient equal or substantially equal to a thermal expansion coefficient of said first substrate, and, in a region of said second substrate, being formed of a second material having a thermal expansion coefficient equal or substantially equal to a thermal expansion coefficient of said second substrate; the thermal expansion coefficient of said first material being different from the thermal expansion coefficient of said second material; and at least one contacting element for electrically contacting one or both of said first and second substrates, said at least one contacting element being electrically conductively connected to one or both of said first and second substrates and passing out of said mold package.
