Abstract
A packaged semiconductor device comprising a stack including a die comprising a functional circuit, and a cap which is wafer bonded to the die for protecting the functional circuit as well as a mold component for packaging the stack. At least the cap and/or the die comprises at least one groove at least partially in contact with the mold component, for increasing adhesion of the mold component to the stack. A corresponding method for manufacturing such a packaged device also is described.
