A gate electrode 14 is formed through a gate oxide film 13 over a channel region 12 in an element region 11, and sidewall dielectric films 16 are provided on side sections of the gate electrode 14. The system includes a spray delivery device configured to release a pressurized substance in response to an activation signal, an activation device configured to transmit an activation signal to the spray delivery device, and a power supply, configured to provide power to at least one of the activation devices and the spray delivery devices. Each portion of the bone may be coupled to at least one mount.
