摘要:
A fully inverted type SOI-MOSFET has a channel region 18 constructed of a portion that belongs to a top silicon layer 13 and is located just under a gate electrode 15 and a source region 16 and a drain region 17, which belong to the top silicon layer 13 and are located adjacent to this channel region 18. The channel region 18 is inverted throughout the entire thickness during operation. The source region 16 has a source resistance RS, which satisfies a relation that (1/gm)>RS with respect to the mutual conductance gm of the channel region 18 itself. According to this fully inverted type SOI-MOSFET, the effective mutual conductance (Gm) can be increased.

摘要:
A method and apparatus for recording and reading information in a recording medium comprising a thin film of an organic compound having polymorphisms. The free energy of each polymorphism is different with each other. Information is recorded in the recording medium by applying energy to the recording medium and transferring locally the polymorphism of the organic compound to another polymorphism of the organic compound. The amount of the energy corresponds to the difference in free energy between the polymorphisms. Information is read from the recording medium by optically discriminating between the optical absorption properties of the polymorphisms.
