TSMC will reportedly manufacture fingerprint sensors for use in the next-generation iPhone series at its 12-inch wafer fabs using 65nm process technology, according to industry sources.

In response, TSMC said the company does not talk about any customer engagements.

For existing iPhone models, fingerprint sensors are being built using TSMC's 0.18-micron process at the foundry's 8-inch facilities, the sources noted.

Apple's Touch ID fingerprint scanner was first introduced in the iPhone 5s series, which helped drive the market for fingerprint-enabled smartphones.

Orders for fingerprint sensors for use in Apple's existing iPhone models demand 30,000-50,000 8-inch wafers a month, the sources disclosed.
