Book excerpt: The availability of silicon planar transistors with DC gains up to 300 at 10-microamps collector current has made it possible to design circuits with very low power consumption. By irradiating a number of commercial types with 1.5 Mev electrons in different circuit configurations, they were shown to be rather susceptible to space radiation. The most sensitive parameters are leakage current and low current gain. The effect on saturation voltages and on matching characteristics of transistor pairs was found to be minor, as long as the DC gain did not fall below 10. Under prolonged irradiation at electron fluxes representative of the inner Van Allen belt most transistor types had leakage currents considerably less than 100nA at emitter-collector biases not exceeding 10V. A few types exhibited leakage currents as high as 500 microamps A due to the formation of surface channels. A total doese of 10 to the 15th power e/sq cm reduced the DC gain in the 5- to 10-microamps A range of most to the transistors to values between 5 and 20. The gain after irradiation was governed by recombination-generation in the base-emitter region, but did not depend significantly on the pre-irradiation gain. Encapsulation of the transistor chip in a dense plastic material proved to be an effective method of preserving the gain under irradiation with a minimum penalty in weight and volume. (Author).

Book Synopsis The Effects of Ionizing Radiation on Transistor Gain by : D. L. Nelson
Download or read book The Effects of Ionizing Radiation on Transistor Gain written by D. L. Nelson and published by . This book was released on 1965 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transistor gain is reduced by ioizing radiation, which affects the transistor surface, and by displacement radiation, which causes lattice defects. The investigation of ionizing radiation damage described in this paper was accomplished with X-rays of photon energy less than 150 kev, which is below the energy necessary for displacement damage in silicon. Experiments were performed on silicon dioxide passivated silicon planar transistors with open leads, in a normal amplifying mode and with other junction bias conditions. AC and DC gain measurements at various injection levels showed a gain degradation dependence on the operating bias conditions. Open leads and back-biasing of each junction during irradiation resulted in considerable damage, with almost complete recovery occurring in most transistors tested when the base emitter junction was forward-biased. Many of the characteristics of the radiation damage observed can be explained by Atalla's model that charge collection at the surface causes a widening of the space charge region, thus increasing the recombination-generation current.
