    • An apparatus and a method for testing a semiconductor device are provided to shorten a development period by facilitating a board design in a DUT parallel expansion process. A first board(100,200,300,400) includes a site and a first application. A DUT(Device Under Test) is loaded on the site. The first application is formed to test the DUT. A second board(600) collects test results through the first application, transmits the test results to a handler, and sorts the test results. An interface connector(700) is formed to connect the first board and the second board to each other electrically. The first board is attached to or detached from a fixing frame(500). The site is composed of a dual site on which two DUTs are loaded.

    • A semiconductor device (10) has a large number of bond pads (24) on the periphery for wirebonding. The semiconductor device (10) has a module (12) as well as other circuitry, but the module (12) takes significantly longer to test than the other circuitry. A relatively small number of the bond pads (20), the module bond pads (20), are required for the module testing due, at least in part, to the semiconductor device having a built-in self-test (BIST) (16) circuitry. The functionality of these module bond pads (22) is duplicated on the top surface of and in the interior of the semiconductor device (10) with module test pads (22) that are significantly larger than the bond pads (24) on the periphery. Having large pads (22) for testing allows longer probe needles, thus increasing parallel testing capability. Duplicating the functionality is achieved through a test pad interface so that the module bond pads (20) and the module test pads (22) do not have to be shorted together. ® KIPO & WIPO 2007
    • 半导体器件(10)在外围具有大量的接合焊盘(24)用于引线接合。 半导体器件(10)具有模块(12)以及其它电路,但是模块(12)需要比其他电路更长的测试时间。 由于至少部分地由具有内置自检(BIST)的半导体器件(BIST)(16),模块测试所需的相对较少数量的接合焊盘(20),模块接合焊盘(20) )电路。 这些模块接合焊盘(22)的功能性被复制在半导体器件(10)的内表面上和在半导体器件(10)的内部,其中模块测试焊盘(22)明显大于外围的接合焊盘(24)。 具有大的用于测试的焊盘(22)允许更长的探针,因此增加了并行测试能力。 通过测试垫接口实现复制功能,使得模块接合焊盘(20)和模块测试焊盘(22)不必一起短路。 ®KIPO&WIPO 2007

    • PURPOSE: An apparatus for performing a self test for boundary scan in a multi-board and multi-drop system is provided to reduce existing overheads by using only a part of BSC(Boundary Scan Cell) within CUT(Circuit Under Test) and a logic gate. CONSTITUTION: A BIST(Built-In Self Test) logic(1) is used for performing a BIST. An address boundary scan cell(2) is used for determining an enable/disable state of a CUT if a JTAG master transfers an address of the CUT and generates an UpdateDR signal. An address register(3) is used for loading the address of the CUT including the BIST. A board enable/disable BSC(4) is used for preventing a transferring operation of all address values when the JTAG master activates a particular CUT and maintains a boundary path. A TDO 3-state driver(5) is activated when the address of the CUT is identical with the address of the JTAG master. A BIST result BSC(6) is used for transferring a result of a BIST operation to the JTAG master after the BIST operation of the CUT is finished.
    • 目的:提供一种用于在多板和多点系统中进行边界扫描自检的装置,以通过仅使用CUT(待测电路)内的一部分BSC(边界扫描单元)和逻辑 门。 构成:BIST(内置自检)逻辑(1)用于执行BIST。 如果JTAG主机传送CUT的地址并产生UpdateDR信号,则地址边界扫描单元(2)用于确定CUT的使能/禁止状态。 地址寄存器(3)用于加载包含BIST的CUT地址。 当JTAG主机激活特定的CUT并保持边界路径时,板卡启用/禁用BSC(4)用于防止所有地址值的传送操作。 当CUT的地址与JTAG主机的地址相同时,TDO 3状态驱动器(5)被激活。 BIST结果BSC(6)用于在CUT的BIST操作完成后将BIST操作的结果传送到JTAG主机。
