摘要： An end point of polarization titration is detected by the steps of passing constant DC pulse having a magnitude of 0.1-100 .mu.A between a pair of detection electrodes immersed in a solution to be titrated, detecting a polarization state generated between the detection electrodes at each current passage before the polarization reaches an equilibrium state and judging the end point based on the detected polarization state. The polarization state is detected by integrating a polarization potential generated at each current passage and the polarization is eliminated by short circuiting the detection electrodes before passing the next DC pulse.

摘要： A maskless exposure method of drawing a circuit pattern includes: moving a substrate with respect to a projection optical system; scanning, by the projection optical system, the substrate in a first direction; shifting a scanning region in a second direction; scanning the substrate in the first direction so that an overlapping part is formed. A plurality of marks different from the circuit pattern are exposed in a vicinity of the overlapping part. The plurality of marks are a set of marks at least including two marks disposed on one side of the overlapping part and two marks disposed on another side of the overlapping part. Deviations between the pair of the scanning regions, an inclination of exposing light, and a yawing angle of a stage are analyzed by measuring deviations of distances among the plurality of marks.

摘要： An average fault ratio is calculated from product characteristics of a product as a target of yield prediction, in order to predict yield accurately in the course of manufacturing the prediction target product.With respect to a reference product, whose wiring pattern is different from the prediction target product but manufactured by the same manufacturing process, a monthly electric fault density is calculated from actually measured data. Respective average fault ratios are obtained from product characteristics of the prediction target product and the reference product. A monthly electric fault density of the prediction target product is obtained by multiplying the monthly electric fault density of the reference product by the ratio of the average fault ratios. The yield is calculated by using the monthly electric fault density of the month in which a yield prediction target lot of the prediction target product was processed.

摘要： Direct exposure equipment having a multiple heads generally conducts overlapping exposure at an exposure area boundary between the heads. In such a case, if the heads are misaligned, a flaw will occur in a pattern shape at an area that is subject to overlapping exposure. To overcome this, TEGs are disposed for evaluating line width and resistance at an overlapping exposure area between the exposure heads and at a returning exposure area formed when direct exposure equipment having a multi-head configuration exposes a substrate. By examining measured values from these TEGs, a misalignment in the multiple exposure heads is detected.
