It is a purpose of the invention to provide a semiconductor device comprising a high density integrated circuit having a large number of insulated gate field effect transistors having minute size and improved performance and uniformity. Upon being unwound from the drum, the individual optical waveguide pieces are available for further assembly. One exemplary energy density is the amount of energy deposited in the treatment region divided by the volume of the treatment region. The fabric-less part may be an automotive interior part such as a pillar trim, headrest, trim panel, instrument panel, door panel, armrest, or part of an automotive seat such as a seat cushion. An electrochemical cell including the electrode assembly is also disclosed. The positional relationship between the edges can affect carrier mobility within the channel region of the transistor structure.
