  • Patent number: 7731826
    Abstract: An electrolytic sensing system for measuring a blocking signal allows for controlled translocation of a molecule, such as DNA, through a fluid channel. A substantially constant electric field supplied by a DC source is applied across the fluid channel and induces translocation of the molecule within the system. An oscillating electric parameter (e.g. current or voltage) supplied by an AC source is also applied across the fluid channel as a means for measuring a blocking signal. The substantially constant electric field can be altered to provide more detailed control of the molecule and, optionally, run a select portion of the molecule through the channel multiple times to provide numerous signal readings. A temperature control stage cools the system, providing further control of molecule translocation. A modified or non-modified protein pore may be utilized in the fluid channel. The system allows for long DNA strands to be sequenced quickly without amplification.

  • Patent number: 7731830
    Abstract: An electroformed tool has an integrated base with channels contacting the tool with heat exchange fluids flowing through the channels during molding or embossing. A blank base is machined with a network of interconnected open channels on a top surface and end flow through passageways communicating with the channels. The tool is used as an electrode to erode the top surface of the blank base using plunge electro discharge machining by lowering the uneven deposit on the bottom of the electroformed tool down onto the top surface of the blank base in the electro discharge machining environment to form a top contoured surface to mate with the uneven deposit on the non-molding side of the substrate. Thermal management fluid channels are thereby conformal to the mold cavity. The tool and base are sealed together.

  • Patent number: 7731833
    Abstract: The present invention relates to methods and apparatus for plating a conductive material on a workpiece surface in a highly desirable manner. Using a workpiece-surface-influencing device, such as a mask or sweeper, that preferentially contacts the top surface of the workpiece, relative movement between the workpiece and the workpiece-surface-influencing device is established so that an additive in the electrolyte solution disposed on the workpiece and which is adsorbed onto the top surface is removed or otherwise its amount or concentration changed with respect to the additive on the cavity surface of the workpiece. Plating of the conductive material can place prior to, during and after usage of the workpiece-surface-influencing device, particularly after the workpiece surface influencing device no longer contacts any portion of the top surface of the workpiece, to achieve desirable semiconductor structures.

  • Patent number: 7731834
    Abstract: A method and apparatus for mixing chemical additives into contaminated liquids and electrolyzing contaminated liquids includes the positioning of a vibratable element, such as a metal spring, within a cylindrical liquid conduit. A treatment additive is introduced into the liquid upstream of the vibratable element and the liquid is directed through the conduit. The flow of the liquid in proximity to the vibratable element causes the element to vibrate and mix the liquid and the additive. The conduit and the vibratable element may be electrically charged such that the flow of the liquid in proximity to the charged and vibrating element causes an electrical charge to be imparted to the liquid. The vibration of the element also prevents fouling.
