Samsung, problems in chip yield? Qualcomm chooses TSMC

It seems that Samsung Foundrythe division of the company dedicated to production chip is not meeting the quality criteria required by Qualcomm, which had relied on it for the manufacture of the Snapdragon 8 Gen 1.

The news comes from the South Korean newspaper TheElec and also outlines one lost which, if effective, could compromise the future of this division of Samsung: Qualcomm would have in fact decided to entrust exclusively to the Taiwanese company TSMC instead of Samsung to produce the chip with a 3nm which will be presented on the market next year.

The motivation lies precisely in the poor yield that Samsung industries are demonstrating in the mass production of Snapdragon 8 Gen 1 chips: the rate of return, i.e. the percentage of processors produced that are actually working, is equal to only 35%.

In other words, the 65% of the processors that Samsung Foundry produces are flawed and therefore unusable, an unacceptable percentage if we also consider the crisis of raw materials in which we have been for more than a year now.

The situation would be even more worrying if it refers to the production of the new Exynos 2200the SoC always with 4nm production process that we find on board the new Galaxy S22, at least according to what anonymous sources have reported to TheElec.

TSMC

In the current state of affairs Qualcomm has called for help TSMC also for the production of the same Snapdragon 8 Gen 1 (and probably its Plus variant coming in the next few months): theorder has already been received by the company, which has already started the production of the parts with delivery scheduled for the second quarter of 2022.

Samsung has meanwhile started ainternal investigation to his Foundry division for this shortage in production yield: the loss of a partner like Qualcomm could in fact have a significant impact at the level of business. The verifications, which are still in progress and involve past and present employees, concern the production of 3nm, 4nm and 5nm chips and the alleged handling yield percentages.
