摘要： A semiconductor device has a sapphire substrate, a semiconductor layer made of GaN provided on the sapphire substrate, a multilayer film provided on the semiconductor layer, and an electrode in ohmic contact with the multilayer film. The multilayer film has been formed by alternately stacking two types of semiconductor layers having different amounts of piezopolarization or different amounts of spontaneous polarization and each containing an n-type impurity so that electrons are induced at the interface between the two types of semiconductor layers. This allows the contact resistance between the electrode and the multilayer film and a parasitic resistance in a current transmission path to be reduced to values lower than in a conventional semiconductor device.

The information sharing apparatus includes information management devices each of which has a pipe management system and communicates with each other to transmit information. The pipe management system includes a pipe management part that manages a set of pipes. Each pipe has detailed items and their weights to represent a relationship between two information management devices. The pipe management system further includes a pipe retrieving part that retrieves a pipe matching a request of the user from the set of pipes managed by the pipe management part and a pipe composing part that generates a new pipe by composing retrieved pipes. The pipe management system transmits user's request to the other systems. Thereby pipes matching the request are composed to expand a pipe held by the system that originally transmitted the request.
