The present invention is directed towards a source of ultraviolet energy, wherein the source is a UV-emitting LED. In an embodiment of the invention, the UV-LED is characterized by a base layer material including a substrate, a p-doped semiconductor material, a multiple quantum well, a n-doped semiconductor material, upon which base material a p-type metal resides and wherein the LED's are provided with a rounded mesa configuration. In a specific embodiment, the p-type metal is positioned upon a rounded mesa, such as a parabolic mesa, formed out of the base structure materials.

A flip chip light emitting diode die (&#x2033;) includes a light-transmissive substrate (&#x2033;) and semiconductor layers (&#x2033;) that are selectively patterned to define a device mesa (&#x2033;). A reflective electrode (&#x2033;) is disposed on the device mesa (&#x2033;). The reflective electrode (&#x2033;) includes a light-transmissive insulating grid () disposed over the device mesa (&#x2033;), an ohmic material () disposed at openings of the insulating grid () and making ohmic contact with the device mesa (&#x2033;), and an electrically conductive reflective film (&#x2033;) disposed over the insulating grid () and the ohmic material (). The electrically conductive reflective film (&#x2033;) electrically communicates with the ohmic material ().

A microvalve and a method of forming a microvalve. The microvalve comprises first and second layers, a diaphragm member and a switching means. The first and second layers are secured together to form a valve body that forms an inlet opening for receiving fluid, an outlet opening for conducting fluid from the valve body, and a flow channel for conducting fluid from the inlet to the outlet. The diaphragm is disposed between the layers, and is movable between open and closed positions. In these position, the diaphragm, respectively, allows and blocks the flow of fluid from the inlet to the flow channel. The diaphragm is biased to the closed position, and moves from the closed position to the open position when the pressure of fluid in the inlet reaches a preset value. The switching means is connected to the valve body for moving the diaphragm to the closed position against the pressure of fluid in the inlet. Preferably, the microvalve is constructed out of SiC and stainless steel materials, allowing the microvalve to be used in a harsh environment.
