In certain embodiments, a semiconductor device can include: a) a contact pad with pre-shaped sidewalls; b) a semiconductor chip having a terminal that is electrically connected to the contact pad, and c) a protective compound covering the semiconductor chip and at least part of the sidewalls. The sidewall can be rough or the sidewall can be tapered to facilitate locking of the contact pad into the compound.
