Cirrus Logic transfers orders towards TSMC

Cirrus Logic has reportedly shifted its orders back to Taiwan Semiconductor Manufacturing Company (TSMC) from Vanguard International Semiconductor (VIS), as the audio chip provider is looking to upgrade its entire product line which will require 12-inch processing.

In response, both TSMC and VIS said they do not comment on speculation about customers and orders.

Cirrus Logic will have TSMC manufacture its audio chips using the foundry's 45/55nm process technologies, according to industry sources.

VIS, which owns only 8-inch fabs, is currently Cirrus Logic's foundry partner, said the sources. Cirrus Logic uses VIS' 0.18-micron process to manufacture its audio chips, the sources added.

Cirrus Logic was previously TSMC's customer, but has shifted its orders to VIS because of tight production capacity at TSMC's 8-inch fabs, the sources indicated.

Orders from Cirrus Logic are able to consume VIS' monthly capacity of almost 30,000 8-inch wafers, the sources noted. The loss of orders will affect negatively VIS' production utilization rate, the sources said.

Cirrus Logic reportedly makes audio chips for Apple.

VIS president Leuh Fang was quoted in previous reports as saying that there is no urgent need for VIS to build 12-inch wafer manufacturing as the areas that the company focuses on do not require larger wafer processing. VIS specializes in analog and mixed-signal ICs, and has expanded its offerings to include wafer manufacturing services for fingerprint sensors and ICs for use in automotive electronics.
