Abstract
A method for reducing soft error rates in semiconductor devices includes adding an isotopically enriched B compound during the manufacture of a semiconductor device. Such isotopically enriched B compounds include orthoborates (BOR ), acyl borates (B(OCOR) ), peroxo borates (OOR) , boronic acids (RB(OH) ), boron halides, boron hydrides, inorganic boranes, amine boranes, aminoboranes, carboranes, and borazines, where R is an alkyl group. Disclosed uses include adding between 1% to 100% of the isotopically enriched B compound to an underfill material in flip-chip assembly; adding between 1% to 100% of the isotopically enriched B compound to an encapsulent; and adding between 1% to 100% of the isotopically enriched B compound to an adhesive.
