A semiconductor device has a substrate having a plurality of metal layers. The apparatus includes a substrate holder assembly having a substrate engaging surface formed thereon, the substrate engaging surface being configured to engage a substrate on the non-production surface. Thereby, the switch for outputting the signal in accordance with a position of a displacement member, the switch being capable of easily outputting the signal in accordance with a desired position of the displacement member without need for an adjusting screw can be provided. The strap is configured to secure the gel pack against the user’s eye region and to exert compressive forces to the gel pack. Embodiments disclosed include lamps having a drive probe and a feedback probe, and lamps having a drive probe, feedback probe and start probe, which minimize power reflected from the body back to the source. As the result, it becomes possible to construct a service association system in which different services can be automatically adapted to the template in addition to the service which simply adapted to the template.
