Because of a large lattice mismatch between a sapphire substrate and a group III-V compound semiconductor, a good crystal is difficult to grow. A high-quality AlN buffer growth structure A on a sapphire substrate includes a sapphire (0001) substrate 1, an AlN nucleation layer 3 formed on the sapphire substrate 1, a pulsed supplied AlN layer 5 formed on the AlN nucleation layer 3, and a continuous growth AlN layer 7 formed on the pulsed supplied AlN layer 5. Formed on the continuous growth AlN layer 7 is at least one set of a pulsed supplied AlN layer 11 and a continuous growth AlN layer 15. The AlN layer 3 is grown in an initial nucleation mode which is a first growth mode by using an NH₃ pulsed supply method. The pulsed supplied AlN layer 5 is formed by using NH₃ pulsed supply in a low growth mode which is a second growth mode that increases a grain size and reduces dislocations and therefore is capable of reducing dislocations and burying the nucleation layer 3. The continuous growth AlN layer 7 is a fast vertical growth mode that improves flatness and suppresses crack occurrences. As examples of the thickness of layers; the pulsed supplied AlN layer 5, 11 is 0.3 μm and the thickness of the continuous growth AlN layer 7, 15 is 1 μm, for example. Characteristics of conditions under which layers are grown are as follows. The AlN layer 3 is grown under a high temperature and a high pressure with a low V-III ratio (less N). The pulsed supplied AlN layer 5 is grown at a low temperature and a low pressure with a high V-III ratio (more N). The continuous AlN layer 7 is grown at a high temperature and a high pressure with a high V-III ratio (Al rich and less N) without using an NH₃ pulsed supply AlN growth method.

A surface treatment, especially for titanium and aluminum alloys, forms a pigmented sol-gel film covalently bonded on the metal surface to produce desired color, gloss, reflectivity, electrical conductivity, emissivity, or a combination thereof usable over a wide temperature range. The coating retains its characteristics and impact resistance following exposures to temperatures at least in the range from −321° F. to 750° F. An aqueous sol containing an organometallic alkoxide containing either Ti or Al and an organosilane with an organic acid catalyst and stabilizer is applied to etched or grit blasted substrates by dipping, spraying, or drenching, to produce bonds in a single application comparable in strength and performance to standard anodize controls. The sol-gel coating may be graded in its ceramic character by adjusting the organosilane component between TEOS and silanes that have more distinctive organic character by virtue of organic ligands attached to the silicon.

The invention discloses an isolated gate field effect transistor and the manufacture method thereof. Through the method of introducing metal when a dielectric layer is grown on a nitride transistor structure, the chemical properties of the dielectric layer are changed, and the effects of controlling etching speed and depth can be played. A groove structure is formed in a grid region in a partially thinned manner, and part of dielectric layer is reserved at the grid. A metal grid is arranged on the dielectric layer in the groove region of the grid, so as to form metal/ dielectric layer/ semi-conductor contact, and meanwhile, the groove is used for forming a field plate structure. Since the surface of a semi-conductor is protected by the dielectric layer during the entire technological process, damages to the surface of nitride, stress releasing and staining on the surface of the nitride can be greatly reduced, and the current collapsing effect of a device can be reduced greatly. Due to the MISFET (Metal Insulation Semiconductor Field Effect Transistor) or MOSFET (Metal-Oxide -Semiconductor Field Effect Transistor) structure is formed by the high-quality dielectric layer, current leakage of the grid can be reduced greatly.
