Abstract


With the development of the aerospace and nuclear technology , more and more electronic devices are used in a radiation environment , radiation will affect the performance and reliability of electronic devices . Degradation of device performance parameters are often derived from the accumulation of material defects . Therefore, in order to guarantee the reliability of electronic devices in a radiation environment , the need for a rapid, sensitive and simple method to evaluate the radiation resistance of electronic materials . The the SiO 2 dielectric material , for example , established a SiO 2 dielectric material radiation resistance noise nondestructive evaluation methods and LabVIEW as a platform to design and realize the electronic material radiation resistance nondestructive Evaluation software system . This paper completed the following tasks : study SiO 2 media , pn junction silicon material radiation damage mechanism analysis of the relationship between the noise and material defects and the SiO 2 < / sub> dielectric material radiation damage noise sensitive characterization methods, SiO 2 noise nondestructive evaluation model parameter extraction methods is given , and the design of non-destructive evaluation program . Based on the above results , using the LabVIEW platform to complete typical electronic material radiation resistance Nondestructive Evaluation software system . Choose a suitable data acquisition boards for the frequency range of the low-frequency noise test , completed the acquisition module of the evaluation system . Continuous acquisition and storage technology , the queue structure to achieve a long continuous acquisition and data storage using LabVIEW platform . On the basis of the evaluation program was designed and implemented the burst noise analysis and evaluation analysis module based on the evaluation model , the SiO 2 medium pn junction with the assessment of the anti- radiation silicon material and forecast .
