LG Chem reportedly developing MR-MUF materials for HBM on top of NCF work

What happened

LG Chem is developing materials for the mass reflow-molded underfill (MR-MUF) process used to make high-bandwidth memory (HBM), Korean media outlet ETNews reported, citing industry sources. The development is still in progress and conditional: if successful, the effort would widen the range of critical HBM materials produced in South Korea and reduce reliance on imports. The source does not state the cause.
