TSMC to Use Current Fingerprint Sensor Processing Method for iPhone 6

iphone_5s_touch_id 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.
Apple previously decided to have TSMC produce fingerprint sensors for its next-generation iPhone at the foundry's 12-inch facilities using a 65nm process, the sources noted. However, acknowledging risks associated with 12-inch WLP technologies, Apple has finally chosen TSMC's 8-inch processing which enables mature yield rates for WLP to produce the fingerprint sensors, the sources said.
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.

This is incredible as it will also as it will provide more security for apple users


I'm sorry, what?

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.


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.

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:


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.

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

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 :)

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

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.

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