Abstract:
Some embodiments of the invention are directed to the electrochemical fabrication of microprobes which are formed from a core material and a material that partially coats the surface of the probe. Other embodiments are directed to the electrochemical fabrication of microprobes which are formed from a core material and a material that completely coats the surface of each layer from which the probe is formed including interlayer regions. These first two groups of embodiments incorporate both the core material and the coating material during the formation of each layer. Still other embodiments are directed to the electrochemical fabrication of microprobe arrays that are partially encapsulated by a dielectric material during a post layer formation coating process. In even further embodiments, the electrochemical fabrication of microprobes from two or more materials may occur by incorporating a coating material around each layer of the structure without locating the coating material in inter-layer regions.
Abstract:
Embodiments of invention are directed to the formation of microprobes (i.e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates.
Abstract:
A process kit is described that resists plasma erosion, preserves the spatial uniformity of plasma properties, reduces particle generation in the chamber, and significantly enhances the lifetime of the process kit. A layer of polymer material covers the top surface of the process kit. The polymer material is fluorocarbon-based and not reactive with the species in the plasma. The polymer material not only protects the process kit from progressive erosion, but also prevents the generation of particles in the chamber. The polymer material has similar permittivity to that of the process kit and therefore maintains the spatial uniformity of plasma properties, e.g., etch rate, near the wafer perimeter. The thickness of the layer is controlled between 0.5 and 1.5 mm such that the difference between its coefficient of thermal expansion and that of the process kit will not cause the layer to peel off the process kit's top surface.
Abstract:
Composite substrates include a silicon layer disposed on a ceramic layer. Different thermal expansion coefficient for the composite substrates can be achieved by changing the thermal expansion coefficient of the ceramic layer. Composite substrates can include two layers of silicon sandwiching a layer of ceramic.
Abstract:
Featured is a device for NMR or MRI signals from excited nuclei as well as related apparatus, systems and methods. The device includes a strip array antenna including one or more conductor and N reactive tuning components, where N is an integer ≧1 at least one of the N reactive components is electrically coupled to each of the one or more conductors as well as to ground/virtual ground. The apparent electrical length of the conductors is tuned with the reactive tuning components so it is equal to be about nλ/4, where n is an integer ≧1 and λ is the wavelength of the signal to be detected. The length of the strip also is such as to be substantially in the approximate range of 1.3 times the depth of interest. The strip conductors are also combined with loop coils to form quadrature detectors.
Abstract:
Methods of applying specialty ceramic materials to semiconductor processing apparatus, where the specialty ceramic materials are resistant to halogen-comprising plasmas. The specialty ceramic materials contain at least one yttrium oxide-comprising solid solution. Some embodiments of the specialty ceramic materials have been modified to provide a resistivity which reduces the possibility of arcing within a semiconductor processing chamber.
Abstract:
Embodiments of the present invention are directed to the formation of microprobe tips elements having a variety of configurations. In some embodiments tips are formed from the same building material as the probes themselves, while in other embodiments the tips may be formed from a different material and/or may include a coating material. In some embodiments, the tips are formed before the main portions of the probes and the tips are formed in proximity to or in contact with a temporary substrate. Probe tip patterning may occur in a variety of different ways, including, for example, via molding in patterned holes that have been isotropically or anisotropically etched silicon, via molding in voids formed in exposed photoresist, via molding in voids in a sacrificial material that have formed as a result of the sacrificial material mushrooming over carefully sized and located regions of dielectric material, via isotropic etching of the tip material around carefully sized and placed etching shields, via hot pressing, and the like.

Abstract:
Embodiments of invention are directed to the formation of microprobes (i.e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates. Some embodiments of the invention transfer probes to permanent substrates prior to separating the probes from a temporary substrate on which the probes were formed while other embodiments do the opposite. Some embodiments, remove sacrificial material prior to transfer while other embodiments remove sacrificial material after transfer. Some embodiments are directed to the bonding of first and second electric components together using one or more solder bumps with enhanced aspect ratios (i.e. height to width ratios) obtained as a result of surrounding the bumps at least in part with rings of a retention material. The retention material may act be a solder mask material.
