Abstract: The methods described herein provide for a radio frequency micro-electromechanical systems switch having two or more resonant frequencies. The switch can be configured as a capacitive shunt switch having a deflectable member coupled between two electrodes over a transmission line. A first insulator can be located between one of the electrodes and the deflectable member to form a capacitive element. The deflectable member can be deflectable between an up-state and a down-state, the down-state capacitively coupling the deflectable member with the transmission line. The degree by which the deflectable member overlaps the first insulator can be adjusted to adjust the capacitance of the capacitive element and the resulting resonant frequency.

Abstract: Systems and methods directed to the use 1002F to build microdevices and biomedical devices. Through the addition of a photosensitizing agent, Epon epoxy resin 1002F can be linked in the presence of UV light, making it useful as a photoresist or as a micropatternable structural material. One embodiment comprises combining 1002F monomer resin with a solvent and a photoinitiator, placing the monomer solution on a surface, exposing the monomer solution to UV light through a mask to initiate linking, and stripping the unlinked polymer away. In another embodiment, 3-D structures are built using two or more layers of sensitized monomer films, each having different sensitivity to light, and the use of a mask containing opaque and semi-opaque regions.

Abstract: A method of forming a semiconductor device is disclosed. A semiconductor substrate is provided that has a first contact and an undoped electroplated lead-free solder bump (610) formed thereon. A device package substrate is provided that has a second contact and a doped lead-free solder layer (510) on the second contact that includes a dopant. The dopant reduces a solidification undercooling temperature of the undoped lead-free solder bump when the dopant is incorporated into the lead-free solder bump. The undoped electroplated lead-free solder bump and the doped lead-free solder layer are melted thereby incorporating the dopant into the undoped lead-free solder to form a doped solder bump (140). The solder bump provides an electrical connection between the first contact and the second contact.

Abstract: Systems and methods are providing for performing high-throughput, programmable, multiplexed assays of biological, chemical or biochemical systems. Preferably, a micro-pallet includes a small flat surface designed for single adherent cells to plate, a cell plating region designed to protect the cells, and shaping designed to enable or improve flow-through operation. The micro-pallet is preferably patterned in a readily identifiable manner and sized to accommodate a single cell to which it is comparable in size. Each cell thus has its own mobile surface. The cell can be transported from place to place and be directed into a system similar to a flow cytometer. Since, since the surface itself may be tagged (e.g., a bar code), multiple cells of different origin and history may be placed into the same experiment allowing multiplexed experiments to be performed.

Abstract: A microfluidic dynamic vapor control system adapted to change the chemistry of small drops by dynamically controlling the vapor content surrounding the drops. The small volume surface area ratio makes this an efficient mechanism for controlling chemistry in nanovolumes. The system uses small reservoirs of material that can produce vapor on demand, and microfluidic channels that direct the vapor into a small chamber that holds a drop of the solution of interest. By changing the vapors that enter the chamber, the chemical composition of the drop can be modified.

Abstract: A plate manufactured to enable samples of cells, micro-organisms, proteins, DNA, biomolecules and other biological media to be positioned at specific locations or sites on the plate for the purpose of performing addressable analyses on the samples. Preferably, some or all of the sites are built from a removable material or as pallets so that a subset of the samples of interest can be readily isolated from the plate for further processing or analysis. The plate can contain structures or chemical treatments that enhance or promote the attachment and/or function of the samples, and that promote or assist in their analyses. Use of the plate advantageously enables the selection and sorting of cells based on dynamic phenomena and the rapid establishment of stable tranfectants.
