An electronic apparatus includes an insulative substrate containing an aluminum-based glass and a layer containing a semiconductive material over the substrate. The fluidized bed reactor in the present invention allows an improved fluidization of catalyst and thus allows an efficient reaction of a hydrocarbon with an oxygen-containing gas in the presence of a catalyst. A first back gate terminal of the primary transistor is coupled to a second back gate terminal of the secondary transistor and the primary transistor is configured to have an output for the buffer circuit. , proximate to the related traffic content in the web page. In particular, the invention relates to packaging which may be hermetically sealed and, during heating, is able to allow a build up of pressure within the packaging, without the packaging exploding or bursting. The first semiconductor device is arranged such that each side thereof is not parallel to that of the second semiconductor device, and that the first semiconductor device is superimposed on the second semiconductor device, when seen from the direction perpendicular to the surface of the substrate.
