    • An apparatus and method for providing external electrostatic discharge (ESD) protection to a semiconductor device, which may or may not include its own ESD protection, are provided. An ESD structure may be associated with each interconnect, either individually or shared between two or more interconnects. Each interconnect includes a contact tip for establishing a temporary electrical connection with a bond pad of the semiconductor device and a contact pad for electrically interfacing the bond pad with external burn-in and/or test equipment. The ESD structure may be implemented, for example, as a fusible element or a shunting element, such as a pair of diodes, a diode-resistor network, or a pair of transistors. The interconnect may be employed as part of an insert including a plurality of interconnects that provides ESD protection to a plurality of integrated circuits of at least one semiconductor device.
    • 提供了一种用于向半导体器件提供外部静电放电(ESD)保护的装置和方法,其可以包括或可以不包括其自身的ESD保护。 ESD结构可以与每个互连相关联,单独地或在两个或更多个互连之间共享。 每个互连包括用于与半导体器件的接合焊盘建立临时电连接的接触尖端和用于将接合焊盘与外部老化和/或测试设备电接口的接触焊盘。 ESD结构可以实现为例如可熔元件或分流元件,例如一对二极管,二极管 - 电阻器网络或一对晶体管。 互连可以用作插入件的一部分,其包括向至少一个半导体器件的多个集成电路提供ESD保护的多个互连。

    • A probe card for testing semiconductor wafers, and a method and system for testing wafers using the probe card are provided. The probe card is configured for use with a conventional testing apparatus, such as a wafer probe handler, in electrical communication with test circuitry. The probe card includes an interconnect substrate having contact members for establishing electrical communication with contact locations on the wafer. The probe card also includes a membrane for physically and electrically connecting the interconnect substrate to the testing apparatus, and a compressible member for cushioning the pressure exerted on the interconnect substrate by the testing apparatus. The interconnect substrate can be formed of silicon with raised contact members having penetrating projections. Alternately the contact members can be formed as indentations for testing bumped wafers. The membrane can be similar to multi layered TAB tape including metal foil conductors attached to a flexible, electrically-insulating, elastomeric tape. The probe card can be configured to contact all of the dice on the wafer at the same time, so that test signals can be electronically applied to selected dice as required.
    • 提供了用于测试半导体晶片的探针卡,以及使用探针卡测试晶片的方法和系统。 探针卡被配置用于与测试电路电气通信的常规测试装置,例如晶片探测器处理器。 探针卡包括具有用于与晶片上的接触位置建立电连通的接触构件的互连基板。 探针卡还包括用于将互连基板物理和电连接到测试装置的膜,以及用于缓冲由测试装置施加在互连基板上的压力的可压缩构件。 互连衬底可以由具有穿透突起的凸起接触构件的硅形成。 或者,接触构件可以形成为用于测试凸起的晶片的凹陷。 膜可以类似于多层TAB带,其包括附接到柔性,电绝缘的弹性体带的金属箔导体。 探针卡可以配置为同时接触晶片上的所有骰子,以便测试信号可以根据需要以电子方式应用于选定的骰子。

    • A spring element used in a temporary package for testing semiconductors is provided. The spring element is compressed so as to press the semiconductor, either in the form of a bare semiconductor die or as part of a package, against an interconnect structure. The spring element is configured so that it provides sufficient pressure to keep the contacts on the semiconductor in electrical contact with the interconnect structure. Material is added and/or removed from the spring element so that it has the desired modulus of elasticity. The shape of the spring element may also be varied to change the modulus of elasticity, the spring constant, and the force transfer capabilities of the spring element. The spring element also includes conductive material to increase the thermal and electrical conductivity of the spring element.
    • 提供了用于测试半导体的临时封装中的弹簧元件。 弹簧元件被压缩以将半导体以裸半导体管芯的形式或作为封装的一部分压在互连结构上。 弹簧元件构造成使得其提供足够的压力以保持半导体上的触点与互连结构电接触。 向弹簧元件添加和/或移除材料,使其具有所需的弹性模量。 弹簧元件的形状也可以改变以改变弹性元件的弹性模量,弹簧常数和力传递能力。 弹簧元件还包括导电材料以增加弹簧元件的导热性和导电性。
