Silicate glasses such as PSG and borophosphosilicate glass are commonly used in semiconductor device fabrication for intermetal layers, i.e., insulating layers deposited between succeedingly higher metal or conducting layers. BPSG has been implicated in increasing a device's susceptibility to soft errors since the boron-10 isotope is good at capturing thermal neutrons from cosmic radiation.〔(Neutron Induced Single Event Upset Dependence on Bias Voltage for CMOS SRAM With BPSG )〕〔(An Accurate and Comprehensive Soft Error Simulator Y. Tosaka, S. Satoh, and H. Oka - Fujitsu Laboratories )〕 It then undergoes fission producing a gamma ray, an alpha particle, and a lithium ion. These products may then dump charge into nearby structures, causing data loss (bit flipping, or single event upset). In critical designs, depleted boron consisting almost entirely of boron-11 is used to avoid this effect as a radiation hardening measure. Boron-11 is a by-product of the nuclear industry. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Borophosphosilicate glass」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
