Phase end point determination is provided to automatically halt the application of energy to tissue. Prior to the application of energy, the phase end point determination is identified by measuring the product of permittivity and conductivity of the tissue to be treated. An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.

A homogeneous marker is formed, possibly by the adsorption of trace amounts of an ambient material such as carbon monoxide gas, at a surface of a deposited material when the plasma in momentarily interrupted during plasma enhanced chemical vapor deposition or other deposition processes involving the presence of a plasma. When the deposited material is etched, the resulting crystal dislocations or adsorbed gas is detected as a marker by optical emission spectroscopy techniques. The accuracy of an end point determination of the etching process can be increased by providing a sequence of such markers within the bulk or volume of the deposited material. The markers, being merely an interface such as a slight crystal dislocation in otherwise homogeneous material, do not affect the electrical, chemical or optical properties of the remainder of the predetermined deposited material and thus the homogeneity of the deposited material is not significantly affected.

Magnets and magnetic particle-labeled reagents are used to capture and/or release magnetic particle-tagged entities for immunohematology diagnostic testing purposes, especially tests performed in blood banking. The magnetic tagged entities may be tagged antibodies, tagged blood cells, tagged universal binding partners, especially tagged lectins and tagged Coombs reagent, and other binding agents such as biotin-avidin, Protein A or G, ligands and their receptors and the like. Separation of unbound material from bound material is effected through the use of one or both the magnetic field effect on the magnetic labeled reactants and the density gradients of layers of an assay construct. Constructs such as chromatographic strip lateral flow format, and liquid phase reactions in suitable vessels with end point determinations that do not require centrifugation to detect reacted entities. Readable labels such as enzymes, fluorophors, chemiluminescent materials, radioactive isotopes, and other labels may be attached to Coombs reagent to provide a readable product of the Coombs reagent with any antibody participating in the assay.

A method for determining a film thickness in a semiconductor substrate is provided. The method initiates with providing multiple layers on the semiconductor substrate. Then, two reflectance spectra are generated where each of the two reflectance spectra are associated with different time periods while an upper layer is being removed. Next, a difference between the two reflectance spectra is calculated. Then, a curve is defined from the difference between the two reflectance spectra. Next, the defined curve is fitted by a known parametric function to determine the film thickness. An endpoint detector and a CMP system are also provided.
