A semiconductor device includes a first MOS transistor and a second MOS transistor of a second conductivity type. The first MOS transistor includes a first main electrode connected to a first potential and a second main electrode connected to a second potential. The second MOS transistor includes a first main electrode connected to a control electrode of the first MOS transistor and a second main electrode connected to the second potential. The control electrodes of the first and second MOS transistors are connected in common. The first and second MOS transistors are formed on a common wide bandgap semiconductor substrate. In the first MOS transistor, a main current flows in a direction perpendicular to a main surface of the wide bandgap semiconductor substrate. In the second MOS transistor, a main current flows in a direction parallel to the main surface of the wide bandgap semiconductor substrate.

The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a studbump connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.

An origami enabled manufacturing system. The system uses origami design principles to create functional materials, structures, devices and/or systems having an adjustable size and/or shape. An operational device can be coupled to a planar substrate shaped and sized to correspond to a desired origami shape of an origami pattern. A plurality of planar substrates can be coupled together by a plurality of connection members that corresponds to one or more crease of the origami pattern. An array of planar substrates can be formed that convert into a three dimensional structure with origami shape. The resulting three-dimensional structure provides smaller projection area, higher portability and deformability.
