21、ntegrated circuits. This test is classified as destructive. The purpose of this test is to establish a method for determining integrated circuit (IC) latch-up characteristics and to define latch-up failure criteria. Latch-up characteristics are used in determining product reliability and minimizing

22、“no trouble found“ (NTF) and “electrical overstress“ (EOS) failures due to latch-up. This test method is primarily applicable to CMOS devices. Applicability to other technologies must be established. The classification of latch-up as a function of temperature is defined in 3.1 and the failure level

23、criteria are defined in 3.2 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 cool-down time period of time between successive applications of trigger pulses or the period of time between the removal of the Vsupplyvoltage and the application of

24、 the next trigger pulse (See Figures 4, 5, and 8 and Table 2.) 2.2 device under test DUT semiconductor product subjected to latch-up test 2.3 ground GND common or zero-potential pin(s) of the DUT NOTE 1 Ground pins are not latch-up tested. NOTE 2 A ground pin is sometimes called Vss. 2.4 input pins

25、all address, data-in control, Vrefand similar pins 2.5 I/O (bi-directional) pins device pins that can be made to operate as an input or output or in a high-impedance state BS EN 60749-29:2011 6 60749-29 IEC:2011 2.6 Isupplytotal supply current in each Vsupplypin (or pin group) with the DUT biased as

26、 indicated in Table 1 2.7 I-test latch-up test that supplies positive and negative current pulses to the pin under test 2.8 latch-up state in which a low-impedance path resulting from an overstress that triggers a parasitic thyristor structure, persists after removal or cessation of the triggering c

27、ondition NOTE 1 The overstress can be a voltage or current surge, an excessive rate of change of current or voltage, or any other abnormal condition that causes the parasitic thyristor structure to become regenerative. NOTE 2 Latch-up will not damage the device provided that the current through the

28、low-impedance path is sufficiently limited in magnitude or duration. 2.9 logic-high level within the more positive (less negative) of the two ranges of logic levels chosen to represent the logic states NOTE 1 For digital devices, a voltage level equal to Vsupplyis used for latch-up testing, except w

29、here otherwise specified in the relevant specification. NOTE 2 For non-digital devices, Vsupply voltage level or the maximum operating voltage that can be applied to that pin as defined in the relevant specification may be used for latch-up testing. 2.10 logic-low level within the more negative (les

30、s positive) of the two ranges of logic levels chosen to represent the logic states NOTE 1 For digital devices, ground voltage level is used for latch-up testing, except where specified in the relevant specification. NOTE 2 For non-digital devices, ground voltage level or the minimum operating voltag

31、e that can be applied to that pin as defined in the relevant specification may be used for latch-up testing. 2.11 maximum Vsupplymaximum operating voltage for operation within performance specifications NOTE 1 The maximum voltage is not the absolute maximum voltage beyond which permanent damage is l

32、ikely. NOTE 2 Maximum refers to the magnitude of Vsupplyand can be either positive or negative. 2.12 no connect pin pin that has no internal connection and that can be used as a support for external wiring without disturbing the function of the device NOTE All “no connect” pins should be left in an

33、open (floating) state during latch-up testing. 2.13 nominal Isupply(Inom) measured dc supply current for each Vsupplypin (or pin group) with the DUT biased at the test temperature as defined in Clause 5 and Table 1 BS EN 60749-29:201160749-29 IEC:2011 7 2.14 output pin device pin that generates a si

34、gnal or voltage level as a normal function during the normal operation of the device NOTE Output pins, though left in an open (floating) state during testing of other pin types, are latch-up tested. 2.15 preconditioned pin device pin that has been placed in a defined state or condition (input, outpu

37、TE Required timing signals may be applied by the latch-up tester, external equipment, and/or external components as appropriate. 2.19 trigger pulse positive or negative current pulse (I-Test) or voltage pulse (Vsupplyovervoltage test) applied to any pin under test in an attempt to induce latch-up (s

38、ee Figures 4, 5 and 8) 2.20 trigger duration duration of an applied pulse from the trigger source (see Figures 4, 5 and 8 and Table 2) 2.21 Vsupplypin (or pin group) all DUT power supply and external voltage source pins (excluding ground pins), including both positive- and negative-potential pins NO

39、TE 1 Generally, it is permissible to treat equal potential voltage source pins as one Vsupplypin (or pin group) and connect them to one power supply. NOTE 2 When forming Vsupplypins (or pin groups), the combination of Vsupplypins with significantly different supply current levels is not recommended

40、as this would make it difficult to detect significant current changes on low supply current pins. 2.22 Vsupplyovervoltage test latch-up test that supplies overvoltage pulses or overvoltage d.c. level to the Vsupplypin under test 2.23 Vsupplyvoltage level applicable voltage level of the Vsupplypin sp

41、ecified in the relevant specification. The Vsupplyvoltage level is used for latch-up testing as the typical logic high level unless otherwise specified (see 2.9) BS EN 60749-29:2011 8 60749-29 IEC:2011 2.24 ground voltage level ground potential used for latch-up testing as the typical logic low leve

42、l, unless otherwise specified (see 2.10) 3 Classification and levels 3.1 Classification There are two classes for latch-up testing. Class I is for testing at room temperature ambient. Class II is for testing at the maximum operating ambient temperature (Ta) or maximum operating case temperature (Tc)

43、 or maximum operating junction temperature (Tj) in the detailed specification. For Class II testing at the maximum operating Taor Tc, the ambient temperature or case temperature (Tc) shall be established at the required test value. For Class II testing at the maximum operating Tj, the ambient temper

44、ature Taor the case temperature Tcshould be selected to achieve a temperature characteristic of the junction temperature for a given device operating mode(s) during latch-up testing. The maximum operating ambient or case temperature during stress may be calculated based on the methods detailed in An

45、nex B. NOTE Elevated temperature will reduce latch-up resistance, and class II testing is recommended for devices that are required to operate at elevated temperature. 3.2 Levels Level defines the I-test current injection value used during latch-up testing. Latch-up passing levels are defined as fol

46、lows: Level A The trigger current value in Table 1 shall be +100 mA as defined in Figure 6 and -100 mA as defined in Figure 7. If all pins on the part pass at least the Level A trigger current values, then the part shall be considered a Level A part. Level B If any pins on the part do not pass the L

47、evel A standard, then the supplier shall determine the minimum passing trigger current requirement for each pin stressed differently than in Level A. The maximum (or highest) passing trigger current value shall be reported in the record for each pin stressed differently than in Level A, and the part

48、 shall be considered to be a Level B part, see 5.2.5. 4 Apparatus and material The apparatus required for this test method includes the following. 4.1 Latch-up tester 4.1.1 General Test equipment capable of performing the tests as specified in this standard. For devices requiring dynamic testing, th

49、e test equipment shall be capable of supplying timing signals and logic setup vectors required to control the I/O pin output states as specified in 5.2.3. The required timing signals and logic vectors may be applied by the latch-up tester itself, external equipment, and/or external components as appropriate. BS EN 60749-29:201160749-29 IEC:2011 9 4.1.2 Vsupplyand their qualification method For the I-test, sink type voltage power supplies shall be connected to all V
