Title: Allyl-or propenyl-naphthalene derivative
Inventor: SHIOBARA TOSHIO
IPC: C07D303/27
Filed: 1992-01-22
Abstract: PURPOSE:To obtain the subject derivative excellent in processability, heat resistance, the strengths of a cured product, etc., and desirable as, e.g. a resin modifier by allylating dihydroxynaphthalene and optionally isomerizing the product. CONSTITUTION:The objective derivative is represented by formula I (wherein G is H or formula II; R<1> is allyl, propenyl or H; and R<2> is H, a 1-6 C (un) substituted monovalent hydrocarbon group or halogen). The derivative in the form of a phenol derivative can easily be synthesized, for example, by allylating dihydroxynaphthalene and optionally isomerizing the product. An epoxy derivative can be prepared by epoxidizing the phenol derivative. The naphthalene derivative of formula I is highly reactive with another epoxy resin, phenol resin or the like and is useful for modifying such resins.

Abstract: PURPOSE:To implement amplifying and switching actions, by modulating the current flowing from a drain electrode to a source electrode based on the expansion and contraction of a depletion layer formed in an operating layer beneath a gate electrode in the vertical (longitudinal) direction with respect to mainly a wafer surface. CONSTITUTION:An N type crystal layer is formed on a semiinsulating GaAs substrate 7. An insulating film 9 is made of a silicon oxide film or silicon nitride film and deposited on the surface of said crystal layer. One or a plurality of circular openings 8 are formed by machining a part of the insulating film 9, which is held between the source electrode 2 and the drain electrode 3. A numeral 11 shows cylindrical holes which are provided by piercing a GaAs N type crystal layer 10 beneath the openings 8 down to the semiinsulating substrate with the insulating film 9 as a mask. A part of the gate electrode metal 12, which is deposited on the insulating film, forms a Schottky barrier junction 13 on the surface of the GaAs crystal layer in the cylindrical hole 11 through each opening 8. Since the Schottky barrier junction is formed in the vertical direction on the surface of the GaAs wafer, a gate width wg can be increased without increasing the area of the element.
