Abstract: An apparatus for use in processing a workpiece to fabricate a microelectronic component is set forth. The apparatus comprises a process container having a process fluid therein for processing the workpiece and a workpiece holder configured to hold the workpiece. A position sensor is employed to provide position information indicative of the spacing between a surface of the workpiece and a surface of the process fluid. A drive system provides relative movement between the surface of the workpiece and the surface of the process fluid in response to the position information. Preferably, the relative movement provided by the drive system comprises a first motion that causes the surface of the workpiece to contact the surface of the process fluid, and a second motion opposite the direction all of and following the first to generate and maintain a column of process fluid between the surface of the process fluid and the surface of the workpiece.

Abstract: A substrate is treated by supplying an etchant and/or deposition gas into a chamber in which the substrate is situated. In order to avoid the problems associated with transportation of toxic gases, the gases required for such processes are delivered directly from a gas generation and delivery system positioned locally to the chamber.

Abstract: A sensor for measuring a physical amount such as an amount of air includes a membrane structure composed of metal stripes sandwiched between first and second insulating layers. A metal layer made of platinum or the like is formed on the first insulating layer and then heat-treated to improve its properties. Then, the metal layer is etched into a form of the metal stripes. The second insulating layer made of a material such as silicon dioxide is formed on the etched metal stripes. Since the metal layer is heat-treated before it is etched into the form of metal stripes, the metal stripes are not deformed by the heat-treatment. The second insulating layer can be formed on the metal stripes without generating cracks in the second insulating layer.

Abstract: Methods are disclosed for forming shaped structures from silicon and/or germanium containing material with a material removal process that is selective to low stress portions of the material. In general, the method initially provides a layer of the material on a semiconductor substrate. The material, which has uniform stress therein, is then masked, and the stress in a portion of the material is reduced, such as by implanting ions into an unmasked portion. The mask is removed, and either the high stress masked portion or the low stress unmasked portion of the material is selectively removed, preferably by an etching process. The portion of the material not removed remains and forms a shaped structure. The various methods are used to form raised shaped structures, shaped openings, polysilicon plugs, capacitor storage nodes, surround-gate transistors, free-standing walls, interconnect lines, trench capacitors, and trench isolation regions.

Abstract: A method is disclosed to form external interconnections to a microfluidic device for coupling of a fluid or light or both into a microchannel of the device. This method can be used to form optical or fluidic interconnections to microchannels previously formed on a substrate, or to form both the interconnections and microchannels during the same process steps. The optical and fluidic interconnections are formed parallel to the plane of the substrate, and are fluid tight.

Abstract: Planarizing solutions, planarizing machines and methods for planarizing microelectronic-device substrate assemblies using mechanical and/or chemical-mechanical planarizing processes. In one aspect of the invention, a microelectronic-device substrate assembly is planarized by abrading material from the substrate assembly using a plurality of first abrasive particles and removing material from the substrate assembly using a plurality second abrasive particles. The first abrasive particles have a first planarizing attribute, and the second abrasive particles have a second planarizing attribute. The first and second planarizing attributes are different from one another to preferably selectively remove topographical features from substrate assembly and/or selectively remove different types of material at the substrate surface.

Abstract: A mask for a selective growth of a solid, is provided in which the solid is selectively grown in a predetermined region of a substrate and growth on other regions is suppressed. A method is also provided for selectively growing a solid on only the predetermined region of a substrate using the mask. In the mask, a surface layer and an underlayer are provided, each having different chemical compositions. Thus, even if the mask is formed on a substrate in an ultra thin film, the generation of mask defects can be suppressed and stability provided to heat and electron beams.

The second measurement mark has a width which is short enough not to be influenced by a deformation caused by the thermal flow phenomenon.

Abstract: Chemical etching methods and associated modules for performing the removal of metal from the edge bevel region of a semiconductor wafer are described. The methods and systems apply liquid etchant in a precise manner at the edge bevel region of the wafer under viscous flow conditions, so that the etchant is applied on to the front edge area and flows over the side edge and onto the back edge in a viscous manner. The etchant thus does not flow or splatter onto the active circuit region of the wafer. An edge bevel removal embodiment involving that is particularly effective at obviating streaking, narrowing the metal taper and allowing for subsequent chemical mechanical polishing, is disclosed.

Abstract: A process and apparatus for determining a real-time etching rate during a plasma mediated etching process. Real-time etching rate determination includes monitoring an interference pattern generated by a direct light beam and a reflected light beam from a wafer surface. A viewing angle for recording the interference pattern is nearly parallel to the wafer plane and at a fixed focal point on the layer to be removed. The direct light beam and reflected light beams are generated in situ during plasma processing.

Abstract: The present invention is a method to avoid deterioration of a dielectric characteristic of a dielectric layer having a low dielectric constant (low k) during a stripping process. The method involves first forming a low k dielectric layer on the surface of a substrate of a semiconductor wafer. Then, a patterned photoresist layer is formed over the surface of the low k dielectric layer. The patterned photoresist layer is then used as a hard mask to perform an etching process on the low k dielectric layer. A stripping process is then performed to remove the patterned photoresist layer. Finally, a surface treatment is utilized on the low k dielectric layer to remove Si—OH bonds in the low k dielectric layer so as to avoid moisture absorption of the low k dielectric layer that causes deterioration of the dielectric characteristic.
