    Last month, a report from Digitimes stated that Apple supplier TSMC was preparing to begin production on fingerprint sensors for the iPhone 6, and was said to be moving to a larger 12-inch fab from the current 8-inch fab to increase production efficiency. However, Digitimes is now reporting that TSMC will once again be utilizing its 8-inch processing for the iPhone 6, as Apple has cited concerns with the yield rate of the 12-inch fab.
    The report also notes that TSMC will continue to contract the packaging process other firms as a result of moving back to the 8-inch processing. Previously, TSMC was said to be handling the packaging process itself in order to centralize control over the component.

    The Touch ID fingerprint sensor was said to be a key factor contributing to the limited supplies of the iPhone 5s at its launch last September, with low yield rates at packaging firm Xintec and iOS 7-sensor integration slowing production. However, with several of those issues ironed out and TSMC now able to utilize a refined process, launch supplies of the next-generation iPhone are likely to be more readily available.

    Somehow Apple has got to get these yield rates (leading to product shortages) under control. If that means sticking with a slightly older but more reliable technology for another generation, I'm all for it. When they can't get their product out to people, no one cares how advanced the technology is.

    Imagine if iPhone 6 didn't get a fingerprint sensor lol

    They got millions of devices to customers. 9 million in one weekend btw. The demand is so high they can't even keep up. I'm not down for Apple withholding technology for a year so some people don't have to wait a month or two to get their devices. Talk about backward thinking.

    I'm sorry, what?

    iPad air with no touch ID was a big deal for many, never mind iPhone 6. It will be murder around here if that happened :)

    I have no problem with this. The Fingerprint sensor works great for me.

    Apple should have spilt the orders between TSMC and UMC. A dual supplier strategy is always safer.

    This also goes to show that 450mm wafer technology is a long ways off from mainstream adoption.

    so we want to know if this will be still in home button or will be on the bottom of the display!!

    I thought TSMC are going / only produce aX chips for Apple, good to know they also produce the fingerprint sensor. Good business for them.

    Won't matter if Apple doesn't make the iPhone 6 much better looking. They have been using the same faceplate since the 1st iPhone, thick bezel, just looks like an old phone.

    Was expecting new and improved fingerprint sensor on the 6. My 5s works like a charm so I'm not pressing for change...

    So in other words it will be as useless to me as the Touch ID on the three 5s units I've had. Thanks Apple.

    Get those yields up and get it on the next iPads too. The number of times I pick up my iPads after using my 5S and I sit with my finger on the home button waiting for it to unlock before remembering that I have to swipe and put in the code is annoying.

    Somehow? It's not that easy especially for someone who has probably never taken a business class to understand supply and demand theories.

    At least Apple's fingerprint sensor is gonna last more than one model.

    I remember the fingerprint sensor on the Motorola Atrix. They probably put a lot of effort into it, right?

    But it was nowhere to be found on the Atrix 2. In fact... no other Motorola smartphone had a fingerprint sensor after the Atrix. Weird.

    I'm glad Apple is sticking with it. I heartily enjoy my iPhone 5S because of it.

    Finger Print security is great...
    i enjoy thoroughly;
    hope developers make good use of this hardware....

    It will provide more security for Apple users. Is there something you dont understand? Nobody in my home or office can access my phone thus making it more secure. Its not that hard to grasp surely? :confused:

    Not everything Apple sources on the semiconductor side is dual sourced. Though that's a sound strategy, it can also lead to significant challenges between foundries - chasing problems they don't need right now.

    Staying on a predictable 8" process while continuing to improve the 12" process is standard practice in this business.

    They will likely second source in the future, however they could also simply tell TSMC they need a second source and let them deal with it. They do that with other suppliers.

    It's not hard to grasp, but it has nothing to do with this article. His comment would have made more sense as a reply to the post talking about the fingerprint sensor in the 5S before it was released. We already have the 5S with a fingerprint sensor, and know that it increases security, so his comment was un-nesscessary.

    Apple will have to open up this feature to developers first. I think the only way to use it currently is via a jailbreak.

    Which is a shame. It would be cool to be able to unlock apps like 1password using your fingerprint instead of having to type in a password every time.

    Note that they didn't get 9 million TO customers that weekend. They simply sold that many.

    The press release is here. It also noted that:

    "Demand for iPhone 5s has exceeded the initial supply, and many online orders are scheduled to be shipped in the coming weeks."

    True, but they always seem to wait until the last second to start building. The delay seems to be mostly about wanting secrecy. If they started too far ahead, there'd be leaks all over. :)
