Alpha radiation sources in low alpha materials and implications for low alpha materials refinement

Traditionally wafer bumps are made from Pb containing solders. Over 20 years ago IBM recognized that 210Pb has a decay chain resulting in a 5.4 MeV alpha particle that induces soft errors. A variety of efforts to produce and characterize low alpha Pb ensued. Work at Honeywell over the past several y...
