27、rt of IEC 60749 provides a test procedure for defining requirements for testing packaged semiconductor integrated circuits and discrete semiconductor devices for ionizing radiation (total dose) effects from a cobalt-60 ( 60 Co) gamma ray source. This standard provides an accelerated annealing test f

28、or estimating low dose rate ionizing radiation effects on devices. This annealing test is important for low dose rate or certain other applications in which devices may exhibit significant time-dependent effects. This standard addresses only steady-state irradiations, and is not applicable to pulse

29、type irradiations. It is intended for military- and space-related applications. This standard may produce severe degradation of the electrical properties of irradiated devices and thus should be considered a destructive test. 2 Terms and definitions For the purposes of this part of IEC 60749, the fo

30、llowing terms and definitions apply. 2.1 ionizing radiation effects changes in the electrical parameters of a device or integrated circuit resulting from radiation- induced charge NOTE These are also referred to as total dose effects. 2.2 in-flux test electrical measurements made on devices during i

31、rradiation exposure 2.3 non in-flux test electrical measurements made on devices at any time other than during irradiation 2.4 remote tests electrical measurements made on devices that are physically removed from the radiation location Page4 EN6074918:2003067-9418 CEI:0220 5 2.5 time-dependent effec

32、ts significant degradation in electrical parameters caused by the growth or annealing or both of radiation-induced trapped charge after irradiation NOTE Similar effects also take place during irradiation. 2.6 accelerated annealing test procedure utilizing elevated temperature to accelerate time-depe

33、ndent effects 3 Test apparatus The apparatus shall consist of the radiation source, electrical test instrumentation, test circuit board(s), cabling, interconnect board or switching system, an appropriate dosimetry measurement system, and an environmental chamber (if required for time-dependent effec

34、ts measurements). Adequate precautions shall be observed to obtain an electrical measurement system with sufficient insulation, ample shielding, satisfactory grounding, and suitable low noise characteristics. 3.1 Radiation source The radiation source used in the test shall be the uniform field of a

35、60 Co gamma ray source. Uniformity of the radiation field in the volume where devices are irradiated shall be within 10 % as measured by the dosimetry system, unless otherwise specified. The intensity of the gamma ray field of the 60 Co source shall be known with an uncertainty of no more than 5 %.

36、Field uniformity and intensity can be affected by changes in the location of the device with respect to the radiation source and the presence of radiation absorption and scattering materials. 3.2 Dosimetry system An appropriate dosimetry system shall be provided that is capable of carrying out the m

37、easurements called for in 4.2. 3.3 Electrical test instruments All instrumentation used for electrical measurements shall have the stability, accuracy, and resolution required for accurate measurement of the electrical parameters. Any instrument- ation required to operate in a radiation environment

38、shall be appropriately shielded. 3.4 Test circuit board(s) Devices to be irradiated shall either be mounted on or connected to circuit boards together with any associated circuitry necessary for device biasing during irradiation or for in situ measurements. Unless otherwise specified, all device inp

39、ut terminals and any others which may affect the radiation response shall be electrically connected during irradiation, i.e. not left floating. The geometry and materials of the completed board shall allow uniform irradiation of the devices under test. Good design and construction practices shall be

40、 used to prevent oscillations, minimize leakage currents, prevent electrical damage and obtain accurate measurements. Only sockets that are radiation resistant and do not exhibit significant leakages (relative to the devices under test) shall be used to mount devices and associated circuitry to the

41、test board(s). Page5 EN6074918:2003067-9418 CEI:0220 6 All apparatus used repeatedly in radiation fields shall be checked periodically for physical or electrical degradation. Components which are placed on the test circuit board, other than devices under test, shall be insensitive to the accumulated

42、 radiation or they shall be shielded from the radiation. Test fixtures shall be made such that materials will not perturb the uniformity of the radiation field intensity on the devices under test. Leakage current shall be measured outside the field of radiation. With no devices installed in the sock

43、ets, the test circuit board shall be connected to the test system such that all expected sources of noise and interference are operative. With the maximum specified bias for the test device applied, the leakage current between any two terminals shall not exceed 10 % of the lowest current limit value

44、 in the pre-irradiation device specification. Test circuit boards used to bias devices during accelerated annealing must be capable of withstanding the temperature requirements of the accelerated annealing test and shall be checked before and after testing for physical and electrical degradation. 3.

45、5 Cabling Cables connecting the test circuit boards in the radiation field to the test instrumentation shall be as short as possible. If long cables are necessary, line drivers may be required. The cables shall have low capacitance and low leakage to ground, and low leakage between wires. 3.6 Interc

46、onnect or switching system This system shall be located external to the radiation environment location, and provides the interface between the test instrumentation and the devices under test. It is part of the entire test system and subject to the limitation specified in 3.4 for leakage between term

47、inals. 3.7 Environmental chamber The environmental chamber for time-dependent effects testing, if required, shall be capable of maintaining the selected accelerated annealing temperature within 5 C. 4 Procedure The test devices shall be irradiated and subjected to accelerated annealing testing (if r

48、equired for time-dependent effects testing) as specified by a test plan. This plan shall specify the device description, irradiation conditions, device bias conditions, dosimetry system, operating conditions, measurement parameters and conditions and accelerated annealing test con- ditions (if requi

49、red). 4.1 Sample selection and handling Only devices that have passed the electrical specifications as defined in the test plan shall be submitted to radiation testing. Unless otherwise specified, the test samples shall be randomly selected from the parent population and identically packaged. Each part shall be individually identifiable to enable pre- and post-irradiation comparison. For device types that are ESD- sensit
