Phison Electronics will begin producing SSD controller chips using a 28nm process at Taiwan Semiconductor Manufacturing Company (TSMC) in the fourth quarter of 2014, according to industry sources.

　　Phison recently remarked that production of its SSD controllers would migrate to 28nm from 55nm in the fourth quarter of 2014, in order to satisfy the stringent power consumption requirements of ultrabooks and similar ultra-thin PCs. The company did not reveal its foundry partner.

　　In addition, with more SSD controller developers set to migrate to 28mm node technology, TSMC is expected to enjoy a pull-in of orders for SSD controllers in 2014, the sources indicated.

　　Marvell has already used TSMC's 28nm process to manufacture its SSD controllers, the sources added.
