    摘要: An arrangement and method for detecting sequential processing effects on devices to be manufactured in a manufacturing process extracts data regarding responses of the devices to a process step in the manufacturing process and data regarding a processing sequence of the devices in that process step. The extracted data is refined before analysis and control chart rules are then applied to the refined data. These control chart rules detect whether there are any unusual processing effects caused by the sequence of processing of the devices in any one of the individual processing steps. Application of control chart rules to the refined data allows an automatic determination of whether there are any rule violations. One or more control charts which have a rule violation are automatically generated when it is determined that there is a rule violation. Process engineers may then use the automatically generated charts to direct their efforts at improving the manufacturing process.

    摘要: An apparatus and method for detecting defect sizes in polysilicon and source-drain semiconductor devices and methods for making the same. Implemented is a double bridge test structure that includes a resistor path of first semiconductor material, such as doped silicon comprising a plurality of strip segments and with interconnection segments. A plurality of strips of second semiconductor material having a substantially lower resistivity are connected to form parallel circuit interconnections with the corresponding strip segments. The test structure is formed by masking techniques wherein a prescribed mask region enables portions of the silicon resistor or deposited polysilicon to be selectively silicided to form silicide and polycide, respectively. One embodiment for testing for defects in a polysilicon layer uses polycide as the low-resistivity strips, enabling the testing of open and short-circuit defects. A second embodiment selectively silicides exposed portions of a source-drain resistor, thereby enabling testing for defects in a source-drain layer of a metal oxide semiconductor. Defect sizes are determined by comparing the measured resistance values with predetermined width and spacings of the strips.

    摘要: An arrangement and method for detecting sequential processing effects on products to be manufactured in a manufacturing process orders a first set of the products in a first specified processing sequence for a first process step in the manufacturing process. In order to prevent any positional trend created at one process step from being carried over into the next process step, the first set of the products is re-ordered into a second, different specified processing sequence for a second process step in the manufacturing process. Data regarding responses of the first set of the products to the process steps are extracted. The extracted data are correlated with the first and second processing sequences and data analysis is performed on the correlated extracted data. These steps are repeated for subsequent sets of the products, so that although the specified processing sequence is different for each of the individual process steps for a set of products, the same processing sequences for the individual processing steps are used for subsequent sets of the products to be manufactured. Since the processing sequences are not randomized from set to set and do not have to be provided to a database, the amounts of interfacing and disk storage needed are greatly reduced.

    摘要: A real-time in-line defect disposition and yield forecasting system for a semiconductor wafer having layer containing devices includes an in-line fabrication inspection tool, a design review station, and a yield management station. The in-line fabrication inspection tool inspects at least two layers of the semiconductor wafer and produces first information including particle size, particle location and number of particles introduced therein for each of these layers. The design review station inspects the layers of the semiconductor wafer and produces second information including layouts of each of the layers. The yield management station is operatively connected to the in-line fabrication inspection tool and to the design review station. The yield management station retrieves the first information and the second information from the in-line fabrication inspection tool and from the design review station. The yield management station determines at least one of a number of killer defects for the devices in each of the layers or a defect sensitive area index for each of the layers using the first and second information. The yield management station also determines a priority for analyzing each of the at least two layers responsive to at least one of the number of killer defects and the defect sensitive area index for each of the layers.

    摘要: The configuration of a faulty line segment in a switch matrix of a programmable logic device is identified using read-back capture. Each original programmable interconnection point (“PIP”) in the line segment is tested by generating routes from a first logic port through the original line segment and PIP, through all PIPs, adjacent to the original PIP to the opposite logic port. Routes through all PIPs adjacent to the PIPs in the line segment from the first logic port to the second logic port, and from the second logic port to the first logic port, are tested to isolate the fault in the line segment.
