MODE OF SEPARATION OF SEMICONDUCTOR PRODUCTS ACCORDING TO THEIR RELIABILITY

摘要

FIELD: the invention provides quality and reliability of semiconductor products as on the production stage, so at application stage. ^ SUBSTANCE: the essence is in that the intensity of noise on two frequencies 1000Hz and 200Hz is measured on a party of semiconductor articles at three different temperatures (0oC, normal and 100oC. The index of the noise spectrum form gamma is calculated according to the formula Where and - a square of effective meaning of noise on frequencies F1 and F2 for each product and for each temperature. An average meaning is found according to three temperatures for each product and according to the value of the middle meaning of the coefficient the product party is separated on reliable and potentially unreliable. ^ EFFECT: increases trustworthiness. ^ 2 tbl
