DigiTimes is reporting that Qualcomm’s S4 chip is currently in very short supply due to high demand. As a direct result, it has forced vendors and manufacturers like Samsung Electronics, LG Electronics, HTC and Sony Mobile Communications to look for alternate suppliers for chips for their devices, according to Taiwan-based handset supply chain makers. The main culprit of the lack of supply? According to DigiTime’s source, it’s 28nm foundry of Taiwan Semiconductor Manufacturing Company which is currently not sufficient and/or the yield rate of the process is not high enough. If the report is accurate, the lack of supply from Qualcomm will mean that other players, such as NVIDIA now have an opportunity to try and nab a few more customers to use their chip solutions.
