A method for analyzing a sample of wafers includes identifying F failure metrics applicable to at least one pattern on each wafer within the sample. Z spatial and / or reticle zones are identified on each wafer, where Z and F are integers. Values are provided for each failure metric, for each zone on each wafer. A point is defined for each respective wafer in an N-dimensional space, where N=F*Z, and each point has coordinates corresponding to values of the F failure metrics in each of the zones of the corresponding wafer. The sample of wafers is partitioned into a plurality of clusters, so that the wafers within each clusters are close to each other in the N-dimensional space. A plurality of clusters is thus identified from the sample of wafers so that within each individual cluster, the wafers have similar defects to each other.

An integrated sensing device is capable of detecting analytes using electrochemical (EC) and electrical (E) signals. The device introduces synergetic new capabilities and enhances the sensitivity and selectivity for real-time detection of an analyte in complex matrices, including the presence of high concentration of interferences in liquids and in gas phases.

A Raman signal detection and analyzing system and a method thereof are disclosed. The Raman signal is generated by emitting an excitation light to a sample. The Raman signal is then modulated by passing through a plurality of optical filter and modulator. The resulting modulated Raman signal comprises two orthogonal components, which intensities are to be computed based on the first harmonic of said modulated Raman signal. The content of a specific analyte within the sample can then be determined based on the ratio of the intensities of the two components.

The invention provides a no-injury blood glucose detector based on blood raman scattering of the blood vessels of the eyes and a detection method. The no-injury blood glucose detector comprises a module for seeking the blood vessels, a laser focus projection module and a signal detecting and analyzing module, wherein the module for seeking the blood vessels, the laser focus projection module and the signal detecting and analyzing module are sequentially connected. The module for seeking the blood vessels is used for seeking and selecting the blood vessels on the surfaces of the conjunctivae or the sclera and locating coordinates of the blood vessels. The laser focus projection module is used for projecting the laser focus to the blood in the selected blood vessels according to the located coordinates of the blood vessels. The signal detecting and analyzing module is used for collecting scattered light generated by the blood in the blood vessels selected by laser radiation, analyzing the blood glucose level according to the raman scattering spectrum analysis of the detected scattered light, and displaying the blood glucose level. The no-injury blood glucose detector based on blood raman scattering of the blood vessels of the eyes and the detection method have following beneficial effects: the blood does not need to be sampled from a patient; consumable items like test paper are not needed either; and the blood glucose can be directly detected and displayed automatically, intelligently and fast in real time under the circumstance of not injuring the human body; and moreover, detecting can be repeatedly carried out many times according to needs, which is beneficial for monitoring the blood glucose.
