The invention includes a single chip having multiple different devices integrated thereon for a common purpose. Wherein, in a protocol assignment table is recorded the connection relations of a network protocol of Extended Firmware Interface, and a driver program corresponding to a network driver interface specification layer. The U-shaped bow itself forms the pull mandrel for the blind rivets. The laser radiation may be patterned prior to exposing the opacifying layer, for example by passing the radiation through a mask. This also reduces routing scaling issue as the routing itself is against the OTU level and not against the embedded lines.
