What does that have to do with Qualcomm's Snapdragon S4 chip, you ask? Well, Qualcomm may have designed the S4, which indeed uses a 28nm manufacturing process, but it is TSMC that actually takes care of its manufacturing. And without the chips, production of the devices that use them may be facing a delay.
Among the devices that use a Snapdragon S4 processor are the HTC One X for AT&T and the HTC One S, which are both expected to hit the shelves this spring, as well as the Panasonic ELUGA Power and the Asus PadFone, which are expected to be made available for purchase in April. Note that the launch of the international version of the HTC One X should not be affected by the manufacturing issues as it uses a different processor, namely the quad-core Tegra 3 by NVIDIA.
Bear in mind, however, that this is nothing but a rumor, so the troubles that TSMC is facing may not be that serious, if existent at all. Hopefully, the aforementioned devices will all launch within their projected time frames. We will be keeping our fingers crossed.
