Qualcomm asks Samsung Foundry and TSMC to each build 2nm Snapdragon 8 prototypes – do phone


In accordance to ETNews (by way of SamMobile), San Diego-based mostly Qualcomm has requested Samsung Foundry to produce a prototype 2nm chipset for the subsequent-technology Snapdragon 8 software processor (AP). The underside line is that the request reveals that Qualcomm is thinking about having Samsung Foundry build an upcoming flagship SoC for the fabless chip designer. If the prototype impresses Qualcomm and the foundry’s yields are passable, Samsung Foundry may obtain an order to manufacture the chip.
You may recall that Samsung Foundry was producing the 4nm Snapdragon 8 Gen 1 AP when Qualcomm got upset over the low 35% yield that Samsung reportedly was reaching. Merely put, this meant that out of each 100 Snapdragon 8 Gen 1 chips produced by the foundry, solely 35 handed high quality management (QC) and might be shipped. And the best way issues work within the trade, Qualcomm had to pay for the chips that failed to go QC.
Qualcomm ended up making a minor redesign to the chip, slapped a brand new title on it (Snapdragon 8+ Gen 1), and let TSMC manufacture it utilizing its 4nm node. TSMC has been producing the Snapdragon 8 sequence since then. Qualcomm is anticipated to introduce the Snapdragon 8 Gen 4 later this yr; TSMC will likely be manufacturing that chip as nicely utilizing its 3nm node. For the Snapdragon 8 Gen 5, there was discuss Qualcomm twin-sourcing the part from each TSMC and Samsung.

The 2nm prototype ordered from Samsung Foundry by Qualcomm is known as a Multi-Wafer Mission (MWP) and the concept is to create a number of chip prototypes on a single wafer. It’s at this stage that the prototype is put by way of the paces to see if the shopper (on this case, Qualcomm) desires to transfer ahead. Qualcomm has reportedly requested TSMC to create a 2nm prototype as nicely. Qualcomm may have to determine between having TSMC or Samsung Foundry produce the Snapdragon 8 Gen 5, or going forward with the twin-sourcing.

Samsung Foundry is meant to give you the option to begin mass manufacturing of 2nm chips within the second half of 2025. The Exynos 2400 AP, used to energy the Galaxy S24 and Galaxy S24+ within the overwhelming majority of nations, is produced utilizing Samsung Foundry’s third-gen 4nm course of (4LPP+). The decrease the method node quantity, the upper a chip’s transistor rely. And the upper a chip’s transistor rely, the extra highly effective and/or power environment friendly that chip is.
