A wrench includes a core plate made of metal and an outer portion such as rubber encloses the core plate. If a packet matches conditions of a particular QoS policy rule, a determination is made as to whether a queue associated with the matched QoS policy rule exists on an egress port that is to forward the packet. The SiC region may be formed through a normal implantation before the second spacer is formed, or the SiC region may be formed through a tilt implantation or deposition epitaxially in a recess having a sigma-shape like sidewall after the second spacer is formed. After processing, the system provides an output on a display device to a radiologist that is in an order and orientation preferred by the radiologist. Electronic systems including such fin-FET devices are also disclosed.
