There are rumours that Samsung foundry division in the semiconductor wafer production process of production defects, Samsung responded that the claim "no basis".

According to media reports, Apple placed a huge chip order with TSMC, but required TSMC to assume the responsibility for unqualified chips.。This situation is very rare in the semiconductor industry。This is mainly because chip companies will cut wafers to make multiple chips, in the process there will be yield problems, some chips do not work properly, some chips do not meet the expected standards, but these costs are usually borne by the purchaser。The huge orders between Apple and TSMC, on the other hand, require billing based on the number of qualified chips, which means that the cost of substandard chips generated during production is borne by TSMC.。Apple could save billions of dollars if it makes such a deal with TSMC。
