DRAM chipmaker Nanya Technology has reported net profits of NT$6.29 billion (US$206 million), or NT$2.61 a share, for the first quarter of 2015. The profits were 26.6% lower than the prior quarter's levels.

Nanya posted consolidated revenues of NT$12.03 billion in the first quarter, down 3.1% on quarter. The company attributed the sequential revenue decrease to falling product ASPs.

Nanya indicated that its wafer shipments increased 3.3% sequentially in the first quarter, but ASPs fell 8.6%. Along with the revenue drop, Nanya's gross margin slid 1.4pp on quarter to 47.2% in the first quarter.

Nanya converted 20% of the company's total wafer start capacity to a "die-shrink" 30nm process in the first quarter, the company disclosed. The proportion will exceed 50% in the second half of 2015, and climb further to 70-80% in 2016, the company said.

Nanya is also looking to transition to a newer 20nm node technology. Nanya senior vice president Lee Pei-ying noted the company is scheduled to move the process to volume production in the second half of 2017.

Lee reiterated Nanya's plans to initially have half of its overall production capacity enter 20nm production. Nanya runs a 12-inch wafer fab capable of producing 60,000 units a month.

In addition, Nanya revised upward its capex budget for 2015 to NT$8.057 billion. NT$1.88 billion will be used for 20nm manufacturing facilities, the company revealed.
