Abstract: The present structure incorporates a police vehicle which is provided with a closed vault securing a VCR in the trunk. A first camera is mounted on the dash. A second camera is mounted on a portable structure such as a clipboard which is removed from the vehicle. A telemetry link from the clipboard to the vehicle is established for transmitting video data to and from the police officer on foot out of the vehicle. Likewise, a digital data transmission link is established with various input and output devices on the clipboard. At the vehicle, one or more images are recorded on a VCR, and digital data can be transmitted from the vehicle to a remote site for communication with a remotely located police computer or other data base to enable enhanced performance in the field.
Abstract: A pressure controlled substrate processing chamber comprising a pressure control ring and a throttling ridge. The pressure control ring is movably disposed proximate the throttling ridge to define a variable flow orifice. The pressure control ring is translated by a ring actuator in response to pressure information retrieved from the processing chamber. The translation of the pressure control ring causes the size of the orifice to change, thus inducing a pressure change within the chamber.
Abstract: The invention provides an apparatus and a method for achieving reliable, consistent metal electroplating or electrochemical deposition onto semiconductor substrates. More particularly, the invention provides uniform and void-free deposition of metal onto metal seeded semiconductor substrates having sub-micron, high aspect ratio features. The invention provides an electrochemical deposition cell comprising a substrate holder, a cathode electrically contacting a substrate plating surface, an electrolyte container having an electrolyte inlet, an electrolyte outlet and an opening adapted to receive a substrate plating surface and an anode electrically connect to an electrolyte. Preferably, a vibrator is attached to the substrate holder to vibrate the substrate in at least one direction, and an auxiliary electrode is disposed adjacent the electrolyte outlet to provide uniform deposition across the substrate surface.
Abstract: A slider which utilizes a set of four pads arranged in a generally rectangular form. The two pads on the leading edge of the slider each include an angled face on their leading edge to facilitate the lift-off of the slider. Behind each leading edge pad is a trailing pad of substantially the same width and separated from the leading pad by a cross-cut channel. The pressure relief provided by the open cross-slot that separates the front and rear pads of each rail of the slider significantly reduces the sensitivity of air bearing pressure to the shape of the disc surface, leading to a very small fly height modulation even when moving over a disc with substantial runout. The rails are separated by a cross-cut. This cross-cut design substantially diminishes the effect of pressure variations which occur owing to the peaks and valleys which exist on discs, especially plastic discs as the slider flies over the surface of the disc.
Abstract: A method of deposition for W or TiW on a silicon wafer in a physical vapor deposition chamber equipped with a clamping ring without incurring arcing problem between the wafer and the clamping ring by utilizing a novel two-step high-pressure/low-pressure process in which a first depositing step is carried out at a relatively high pressure above 11 mTorr so as to form an electrical bridge between the wafer and the clamping ring and a second depositing step is carried out at a lower pressure so as to form a high-quality conductive film.
Abstract: The present invention provides an electro-chemical deposition system that is designed with a flexible architecture that is expandable to accommodate future designs and gap fill requirements and provides satisfactory throughput to meet the demands of other processing systems.

Abstract: Apparatus for retaining a workpiece on a workpiece support and method for manufacturing same. The apparatus contains an adhesive layer, an insulating layer made of a base material having a first resistivity, an electrode layer, a hybrid/adhesive layer and a workpiece support layer made of a base material and a dopant, the dopant having a second resistivity wherein a resistivity of the resultant workpiece support layer is lower than the first resistivity. The multi-resistivity layers establish a Johnsen-Rahbek effect for electrostatic chucking while not unduly compromising chuck strength or longevity. The method consists of the steps of disposing an adhesive layer, disposing an insulating layer, disposing an electrode layer, disposing a hybrid/adhesive layer, disposing a workpiece support layer, curing the layers and forming a plurality of grooves in the workpiece support layer.
Abstract: The invention relates to an apparatus and process for the vaporization of liquid precursors and deposition of a film on a suitable substrate.

Abstract: A vacuum chuck is disclosed which has nipples as support structure and for vacuum delivery. In the preferred embodiment, two types of nipples are used: “plain” nipples which provide only support and vacuum nipples which provide support and deliver vacuum to retain the wafer on the chuck. The contact surface of the plain nipples is made smaller than that of the vacuum nipples. The chuck is secured to a stage using special supports which have limited flexibility in two axis with respect to the chuck, so as to prevent warping the chuck. Special vacuum nipples are disclosed which do not deliver vacuum unless the wafer exerts sufficient predetermined pressure on the nipple. The chuck is designed to hold both 200 mm and 300 mm wafers.

Upon completion of the deposition process, the central body and ring shaped body are removed from the workpiece support chuck leaving deposits of the material to form the wafer spacing mask.
Abstract: The present invention provides a method of depositing a carbon doped silicon oxide film having a low dielectric constant (k).

Abstract: A conductive feedthrough connector for conducting electrical current through a ceramic body. A ceramic body is generally fabricated by stacking a plurality of layers of ceramic material and then sintering the stack of layers to cure the layers into a unitary, solid ceramic body. In accordance with the present invention, as each layer is positioned, a portion of the layer is silk screened with conductive material prior to the next layer being positioned atop the silk screened layer. Each silk screen region is coaxially aligned along an axis through the ceramic body. The stack of silk screened layers are then sintered to form a solid ceramic body containing the plurality of stacked metal electrodes. A first conductor is then formed vertically into the ceramic body to interconnect the embedded electrodes. From the opposite side of the ceramic body, a second conductor is formed into the surface passing through and interconnecting one or more the layers of electrodes.
