摘要:
A batteryless inverter allows for a positive or a negative lead from a photovoltaic array to be attached to a grounding terminal of the inverter. Internally a ground fault voltage is rectified and processed to produce a signal that will shut down the inverter. This signal will be the same whether the ground fault voltage is positive, negative, or AC.

An integrated circuit current sensor includes a lead frame having at least two leads coupled to provide a current conductor portion, and a substrate having a first surface in which is disposed one or more magnetic field sensing elements, with the first surface being proximate to the current conductor portion and a second surface distal from the current conductor portion. In one particular embodiment, the substrate is disposed having the first surface of the substrate above the current conductor portion and the second surface of the substrate above the first surface. In this particular embodiment, the substrate is oriented upside-down in the integrated circuit in a flip-chap arrangement. The current sensor can also include an electromagnetic shield disposed between the current conductor portion and the magnetic field sensing elements.

摘要:
A coating for sensor transducers that transmit a signal to—and/or receive a signal from—a fluid, either liquid or gas, in contact with the transducer. In particular the coating minimizes or eliminates fouling of the transducer surface by the fluid, reducing the need for transducer maintenance, while not interfering with the transducer's ability to send and/or receive signals.

The structurally independent load bearing support system comprises at least two side frames comprising a plurality of longitudinally spaced vertical members and at least one transverse member connecting the two side frames.
摘要:
Photoresist, which contains hydrogen, is patterned over a semiconductor substrate then treated with either a molecular halogen or a liquid fluorinating agent in order to improve subsequent ion implantation. Hydrogen is replaced, to whatever extent is found desirable, with the halogen. Molecular fluorine (F2) has been found to be particularly effective as the molecular halogen. Molecular fluorine (F2) reacts very efficiently in replacing the hydrogen and further has the benefit of continuing to penetrate into the patterned photoresist so that the entire patterned photoresist layer can have the hydrogen atoms replaced with fluorine atoms if the molecular fluorine flow is continued long enough. The resulting treated photoresist is much more resistant to penetration by implanted ions so that the photoresist can be deposited to a lesser thickness. This is beneficial in shadowing problems such as can occur in halo implants and where the patterned photoresist has a high aspect ratio.

摘要:
A semiconductor device and fabrication process includes forming a gate dielectric overlying a semiconductor substrate and a gate electrode overlying the gate dielectric. The gate electrode includes an interface between a first portion of the gate electrode and a second portion of the gate electrode. A silicide is then formed overlying the gate electrode. The presence of the gate electrode interface substantially prevents the silicide from spiking into or through the gate electrode to encroach upon or contact the underlying gate dielectric. Forming the gate electrode may include forming a polysilicon first gate electrode layer and forming an amorphous silicon layer over the polysilicon first gate electrode layer. Forming the second gate electrode layer may include forming a SiGe first sublayer and a polysilicon second sublayer.
