发明名称 Multi-purpose planarizing/back-grind/pre-underfill arrangements for bumped wafers and dies
摘要 Multi-purpose planarizing/back-grind/pre-under-fill arrangements for bumped wafers and dies, in which a planarizing coating provides improved and continued surface protection to the circuit surface of a wafer or die throughout back-grinding and subsequent mounting operations, and provides improved stiffening/strengthening of the wafer and die throughout back-grinding and subsequent mounting operations.
