    摘要: A heterobipolar transistor (HBT) for high-speed BiCMOS applications is provided in which the collector resistance, Rc, is lowered by providing a buried refractory metal silicide layer underneath the shallow trench isolation region on the subcollector of the device. Specifically, the HBT of the present invention includes a substrate including at least a subcollector; a buried refractory metal silicide layer located on the subcollector; and a shallow trench isolation region located on a surface of the buried refractory metal silicide layer. The present invention also provides a method of fabricating such a HBT. The method includes forming a buried refractory metal silicide underneath the shallow trench isolation region on the subcollector of the device.

    摘要: Abstract of the DisclosureABSTRACT OF THE DISCLOSURE Gas generating and releasing articles consisting essentially of a polymer and a gas generating solid dispersed therein are described. The article generates and releases a gas in response to moisture and in the absence of an acid, a polymer that degrades to produce an acid, a compound that generates an acid in response to humidity, a hygroscopic compound, and an oxidant. The article may also generate and release a gas in response to energy.
