    • 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.
    • 用于检测对在制造过程中制造的产品的顺序处理影响的布置和方法,以在制造过程中的第一处理步骤的第一指定处理顺序中对第一组产品进行订购。 为了防止在一个处理步骤中产生的任何位置趋势被转移到下一个处理步骤中,将第一组产品重新排列成制造过程中第二个处理步骤的第二个不同的指定处理顺序。 提取关于第一组产品对处理步骤的响应的数据。 提取的数据与第一和第二处理序列相关,并且对相关的提取数据进行数据分析。 对于随后的产品组重复这些步骤,使得尽管对于一组产品的各个处理步骤的指定处理顺序是不同的,但是用于各个处理步骤的相同处理顺序用于随后的产品集合 被制造。 由于处理序列不是从集合中随机化设置的,并且不必提供给数据库,因此大大减少了所需的接口和磁盘存储量。

    • 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.

    • 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.

    • An automated system and procedure processes wafer test bin data of semiconductor wafers to formulate a fault pattern at statistically significant levels. A processor such as a neural engine or neural network collects wafer test bin results to generate a N/N wafer map to be correlated with wafer maps produced from a wafer electrical test, a wafer level reliability test, and an in-line defect analysis. A N/N wafer map generated by the processor is cross-checked with a wafer map generated from another semiconductor tester to formulate possible overlap fault patterns. The confirmed fault patterns are further analyzed by performing failure analysis to find the root cause of fault patterns. A report containing fault patterns and the root cause for fault patterns is sent back to a fab for making adjustment to the fabrication process to increase the overall yield of the future batch of semiconductor wafers. The report is also stored in a pattern database to serve as a library for future reference of previously recognized fault patterns, thereby to bypass the need to perform a failure analysis for matching fault patterns.
