A method of identifying failures in a metrology tool system used to measure desired dimensions in microelectronic features. Each metrology tool in the system runs a plurality of recipes for measuring desired dimensions in microelectronic features, with each recipe comprising a set of instructions for measuring at least one dimension in a microelectronic feature. The system includes an error log having stored thereon failures in measurement of microelectronic feature dimensions. The method includes determining normalized number of errors for the recipes used by the metrology tool from the failures stored in the error log, identifying one or more recipes having the greatest normalized number of errors in the error log, identifying, in a list of jobs to be performed by the metrology tool, the one or more identified recipes having the greatest normalized number of errors, and from the identified one or more recipes having the greatest normalized number of errors, determining the cause of the errors in the one or more recipes. The method then includes effecting a change in the one or more identified recipes having the greatest normalized number of errors to correct the errors therein and tracking a metrology tool job having the one or more recipes in which a change has been effected to determine whether the cause of errors has been corrected.

The present invention is drawn to compositions and methods of generating epoxide group-functionalized latex particulates in a liquid suspension, as well as compositions and methods of preparing ink-jet inks. Steps of the methods can include forming an emulsion including a continuous hydrophilic phase and a discontinuous hydrophobic phase, wherein the discontinuous hydrophobic phase includes a plurality of monomers. The plurality of monomers can comprise epoxide group-forming monomers and support-forming monomers. Other steps include copolymerizing the monomers to form precursor latex particulates dispersed within the hydrophilic phase, and reacting the precursor latex particulates with a base to form epoxide group-functionalized latex particulates.

Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.

A magnetoresistive sensor for detecting stored information from a magnetic medium and for providing an output voltage to auxiliary circuitry is disclosed. The magnetoresistive sensor includes a magnetoresistive magnetic layer formed from a magnetic material, the magnetic layer having a magnetization, a resistivity and a thickness. A resistance of the magnetic layer equals the resistivity of the layer divided by the thickness of the layer. The magnetic sensor also comprises a bias layer having a resistivity, a thickness and a saturation inductance. A resistance of the bias layer equals the resistivity of the layer divided by the thickness of the layer. The resistance of the bias layer is in parallel with the resistance of the magnetic layer. The saturation inductance of the bias layer helps to bias the magnetic layer from a rest position to a magnetized position. A spacer layer is positioned between the magnetic layer and the bias layer. The spacer layer has a resistivity and a thickness. A resistance of the spacer layer equals the resistivity of the layer divided by the thickness of the layer. The resistance of the spacer layer is in parallel with both the resistances of the magnetic layer and the bias layer. The parallel resistances of the bias layer and the spacer layer is at least twice as large as the resistance of the magnetic layer such that at least two-thirds of the current flows through the magnetic layer and at most one-third of the current flows through the combination of the bias layer and the spacer layer.

A diagnostic and therapeutic apparatus for gastrointestinal diseases which has a central control unit a set of diagnosis and therapy lead electrodes, diagnosis and therapy switch, acupunctural point stimulating pulse amplifier, display, and a human body spectrum generator. During the diagnostic operation, bioelectric signals from a patient stomach received by the lead electrodes are supplied to the central control unit via the switch and displayed on a display. During the therapeutic operation, the human body spectrum generator radiates a simulated human body spectrum which matches with the spectrum of the human stomach to reinstate the abnormal spectrum of the patient so that gastrointestinal diseases can be cured. Meanwhile, the acupunctural point stimulating pulse amplifier introduces point stimulating pulses to the relevant accupoints of the patient body via the switch and lead electrodes for therapeutic purpose.
