    • According to the present embodiment, a method for calculating the parasitic capacitance in a semiconductor device is disclosed. According to the preferred method, a layout file containing the shapes of a semiconductor device is provided. The dimensions of the layout file are then adjusted to wafer dimensions so as reflect actual production devices. The shapes of the layout file are then partitioned into simpler shapes, typically abutted rectangles, called tiles. Each tile is then decomposed into overlap and fringe capacitance components, each component having a uniform capacitance environment with respect to its capacitance elements. The parasitic capacitance of the semiconductor device can thus be accurately computed, with an efficient use of resources. Additionally the preferred embodiment is easily adaptable to a wide range of technology types.
    • 根据本实施例,公开了一种用于计算半导体器件中的寄生电容的方法。 根据优选方法,提供了包含半导体器件的形状的布局文件。 然后将布局文件的尺寸调整为晶圆尺寸,以反映实际的生产设备。 然后,布局文件的形状被分割成更简单的形状,通常是称为块的邻接矩形。 然后,每个瓦片被分解成重叠和边缘电容分量,每个部件相对于其电容元件具有均匀的电容环境。 因此,可以有效利用资源来准确地计算半导体器件的寄生电容。 此外,优选实施例容易适应于广泛的技术类型。

    • A method of testing a semiconductor wafer and a related structure. In various embodiments, a method includes: placing a probe on a first chip on the semiconductor wafer; testing a scribe line automatic built-in self-test (ABIST) for the first chip to search for a fault; progressively testing a subsequent scribe line ABIST for a subsequent chip on the semiconductor wafer in response to determining the ABIST for the first chip does not indicate the fault; moving the probe point to the subsequent chip and retesting the subsequent scribe line ABIST in response to determining the ABIST for the subsequent chip indicates a fault; and testing a further subsequent scribe line ABIST for a further subsequent chip on the semiconductor wafer in response to determining the retesting of the subsequent scribiline ABIST does not indicate a fault in the subsequent scribe line ABIST.
    • 一种半导体晶片的测试方法及相关结构。 在各种实施例中,一种方法包括:将探针放置在半导体晶片上的第一芯片上; 测试划线自动内置自检(ABIST)为第一芯片寻找故障; 响应于确定第一芯片的ABIST而对半导体晶片上的后续芯片进行随后的划线ABIST的逐步测试不表示故障; 将探针点移动到随后的芯片,并且响应于确定随后芯片的ABIST指示故障,重新测试随后的划线ABIST; 以及响应于确定随后的scribiline的重新测试,测试另一后续划线ABIST用于半导体晶片上的另外的后续芯片,ABIST不指示后续划线ABIST中的故障。
