Samsung and GlobalFoundries recently announced that develop 14 nm process using FinFET-structures will be a united front. Moreover, customers will be able to access any of these companies, as well as to migrate between them without making significant changes to the process.
Samsung offers to UMC to join an alliance with Globalfoundries was refused, fearing the high license fees and other hidden costs. It was assumed that UMC will also be able to use the operating time of the alliance and offer clients issue 14-nm semiconductor with FinFET-layout. Alliance should become a counterweight to TSMC, but UMC is not yet ready to join.
