摘要:
A complementary bipolar transistor is fabricated using an available a portion of a silicon germanium (SiGe) low temperature epitaxial layer as the raised base region for a vertical NPN transistor, and another portion of the same SiGe LTE layer as a vertical PNP collector layer. The complementary pair of transistors is vertically aligned and operates in a single direction.

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:
A device and method for reducing patient transthoracic impedance for the purpose of delivering a therapeutic current are provided. In one embodiment, the device for reducing patient transthoracic impedance for the purpose of delivering a therapeutic current may be used in a defibrillator. The device for reducing patient transthoracic impedance for the purpose of delivering a therapeutic current may be a microneedle array that may have a number of different configurations and may be made with different materials.

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.
摘要:
A composition for energy-controlled generation and release of at least one gas, which includes an energy-activated catalyst capable of being activated by electromagnetic energy, and a solid or a liquid containing anions capable of being oxidized by the activated catalyst or reacted with species generated during activation of the catalyst to generate at least one gas. The composition, when exposed to electromagnetic energy, is capable of generating and releasing the gas after activation of the catalyst and oxidation or reaction of the anions.
摘要:
Members of the TGF-β superfamily control many physiologic and pathophysiologic processes in multiple tissues and signal via type II and type I receptor serine kinases. Type II activin receptors are promiscuous and known to bind 12 TGF-β ligands including activins, myostatin, BMPs and nodal. Methods are described for the screening and identification of antagonist for TGF-β superfamily members, in particular activin-A antagonist.
