    摘要: A III-V compound semiconductor structure comprises epitaxial structures that include an integrated pair of different types of active devices. The semiconductor structure includes a semi-insulating substrate of a compound semiconductor III-V material and a first compound semiconductor III-V epitaxial structure disposed on the substrate. A concentration profile of dopant material in the semiconductor structure decreases substantially smoothly across an interface between the substrate and the first epitaxial structure in a direction from the first epitaxial structure toward the substrate, and continues to decrease substantially smoothly from the interface with increasing depth into the substrate despite the presence of silicon or oxygen contaminant at the interface. The interface is substantially free of a second contaminant that was present, during formation of the first epitaxial structure, in a chamber in which the first epitaxial structure was formed.

    摘要: An integrated pair of HBT and FET transistors shares a common compound semiconductor III-V epitaxial layer. The integrated pair of transistors includes a semi-insulating substrate of a compound semiconductor III-V material, a first epitaxial structure disposed on top of the substrate, a second epitaxial structure on top of the first epitaxial structure, and a third epitaxial structure disposed on top of the second epitaxial structure. The first epitaxial structure forms a portion of the HBT transistor. A concentration profile of a first contaminant, which contributes electrical charge, decreases substantially smoothly across an interface between the semi-insulating substrate and the first epitaxial structure. In some cases, the interface is free of a second contaminant that was present, during formation of the epitaxial structures, in a chamber in which the epitaxial structures were formed.

    摘要: Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross-linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with “easy-open” end closures.
