BS IEC 62615:2010 4 62615 IEC:2010 INTRODUCTION Interest in TLP testing is growing rapidly in the testing of electronic components in the semiconductor industry. TLP testing techniques are being used for semiconductor process development, device
21、and circuit design. This technique or practice is being utilized on products in both wafer level and packaged environments. TLP testing is used as an electrostatic discharge (ESD) characterization tool to obtain voltage-current pulse characterization parameters, failure levels, and ESD metrics. The
22、TLP technique is being used today as a standard measurement for ESD devices. The TLP system to the ESD engineer is becoming a tool as critical as the parameter analyzer is to the semiconductor engineer. The majority of TLP systems are designed by engineers in a laboratory environment. A number of co
23、mmercial TLP systems have been marketed in the industry. Hence it is clear a TLP specification was needed for the TLP vendors, semiconductor industry and product customers to be able to make valid data comparisons. With the usage of TLP data for ESD characterization, technology benchmarking, and pro
24、duct quality evaluation, there is a growing need to have standard methodologies, failure criteria, and means of reporting to allow dialogue between semiconductor suppliers, vendors, and product customers. This document defines the standard test method used today in the semiconductor industry for TLP
25、 testing method and techniques in both industrial and academic institutions (this document is intended to be used by electrical technicians, electrical engineers, semiconductor process and device engineers, ESD reliability and quality engineers, and circuit designers). The context of this document i
26、s the application of TLP techniques for the electrical characterization of semiconductor components. These semiconductor components can be single devices, a plurality of devices, integrated circuits, or semiconductor chips. This methodology is relevant to both active and passive elements. This test
27、method is applicable to diodes, MOSFET devices, bipolar transistors, resistors, capacitors, inductors, contacts, vias, wire interconnects, and related components.

28、bject This International Standard defines a method for pulse testing to evaluate the voltage current response of the component under test and to consider protection design parameters for electro-static discharge (ESD) human body model (HBM).

The scope and focus of this document pertains to TLP testing techniques of semiconductor components. This document should not become alternative method of
