Patent TW-550876-B (TW)
Title: RMS-to-DC converter with fault detection and recovery
Inventor: PETROFSKY JOSEPH GERARD
IPC: G01R19/02
Filed: 2001-12-13
Granted: 2003-09-01
Abstract: A circuit that provides the root-mean-square (RMS) value of an input signal and that detects and independently recovers from an output fault condition is provided. The circuit includes reconfigurable circuitry that changes from normal operating mode to fault recovery mode when an output fault is detected. During fault recovery mode, the circuit provides a modified output signal that allows independent recovery from an output fault condition. Once recovery is complete, the circuit returns to normal operating mode and provides a DC output signal proportional to the RMS value of an AC input signal.

Title: Wide bandgap semiconductor structure, semiconductor device including the structure, and methods of forming the structure and device
Inventor: DROOPAD RAVINDRANATH
IPC: H01L21/20
Filed: 2001-12-26
Granted: 2003-05-11
Abstract: High quality epitaxial layers (26) of wide bandgap materials can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer (24) on a silicon wafer (22). The accommodating buffer layer (24) is a layer of monocrystalline oxide or nitride spaced apart from the silicon wafer (22) by an amorphous interface layer of silicon oxide (28). The layer of wide bandgap material (26) can be used to form electronic devices such as high frequency devices or light emitting devices such as lasers and light emitting diodes.

Granted: 2003-05-01
Abstract: A 4-20 nm silicon oxide film is formed on the surface of a polycrystalline silicon at a processing temperature lower than 500 DEG C by use of OZONE (O3) to perform an Oxidation process to the polycrystalline silicon film adopped with Boron or phosphorus with an economical non-annealing glass as a substrate. Hence, the level density of the junction between the gate isolating film and the channel layer is reduced, and a thin film transistor with fewer-changing properties is formed on the non-annealing glass.

Title: Semiconductor light emitting element
Inventor: TADATOMO KAZUYUKI
IPC: H01L33/32
Filed: 2002-03-20
Granted: 2003-06-11
Abstract: An undulation la is formed on the surface of a first layer 1, and a second layer 2 having a refractory index different from that of the first layer 1 is grown to fill the undulation la. (Or a first crystal 10 is grown in an undulated shape on a crystal layer S which is the foundation of growth.) After such undulated refractory interface 1a (10a) is formed, a semiconductor crystal layer containing a light emitting layer A is laminated thereon to form an element structure. Thereby the lateral light produced in the light emitting layer changes its direction because of the effect of the undulated refractory interface and is directed outwards. On this construction, if InGaN is used as the material for the light emitting layer for emitting an ultraviolet ray, a quantum well construction is employed and the layer between such quantum well construction and a low temperature buffer layer is formed of GaN crystal; A1GaN is excluded, preferably the quantum well construction is made with a well layer of InGaN and a barrier layer of GaN, with the thickness of the barrier layer in between 6 nm to 30 nm preferably.
