  • Patent number: 8649990
    Abstract: A method of detecting variance by regression model has the following steps. Step 1 is preparing the FDC data and WAT data for analysis. Step 2 is figuring out what latent variable effect of WAT data by Factor Analysis Step 3 is utilizing Principal Component Analysis to reduce the number of FDC variables to a few independent principal components. Step 4 is demonstrating how the tools and FDC data affect WAT data by Analysis of covariance model, and constructing interrelationship among FDC, WAT and tools. The interrelationship can point out which parameter effect WAT significantly. By the method, when WAT abnormal situation happened, it is easier for engineers to trace where the problem is.

  • Patent number: 8510610
    Abstract: The instant disclosure relates to a raw data compression method for the fabrication process. The method includes the steps of: inputting into a signal converter a collection of raw data points representing operational parameter of a semiconductor equipment within a predetermined time period; obtaining an approximation of the raw data points with a Fourier series; computing the Fourier coefficients and the residuals between the raw data points and the corresponding predicted values predicted by the Fourier series; determining if the residuals exceed an error threshold; recording and storing the Fourier coefficients as the compressed data if none of the residuals exceeds the error threshold; and recording the raw data point as abnormal data point if the corresponding residual exceeds the error threshold before recording and storing the Fourier coefficients and the abnormal data point as the compressed data.

  • Publication number: 20130029109
    Abstract: The present invention discloses a conductive film including a substrate, a reflective index adjusting structure, and a transparent conductive layer. The reflective index adjusting structure may be disposed on the substrate, and the transparent conductive layer may be disposed on the reflective index adjusting structure, which may be disposed between the transparent conductive layer and the substrate. The transparent conductive layer may cover parts of the reflective index adjusting structure. When a light enters into the transparent conductive layer/the reflective index adjusting structure of the conductive film with an incident angle, the light may be associated with a first reflectance/a second reflectance. The difference between the first reflectance and the second reflectance is designed to be lower than a first threshold value. Accordingly, the present invention may eliminate the display difference between an etched and a non-etched area of the conductive film and improve the visual quality.
