During the fiscal year under review, there was a sense that semiconductor demand had bottomed out in the second half of the year. Nevertheless, demand for memory was significantly lower as well as the impact of inventory adjustments, conditions remained challenging in the semiconductor market.
We focused on allocating management resources in growth markets, including the decision to make additional capital investments for the Takaoka Plant in Nakano City, Nagano prefecture, as well as other plants, beginning in fiscal year 2018 with the aim of strengthening production systems for next-generation flip-chip type packages suited to nano-fabrication and high-density semiconductors, the sequential installation of equipment and construction of production lines. Under difficult circumstances caused by deteriorating memory market conditions, and we actively engaged in sales activities to receive orders, as well as lowering costs and ramping up production to secure profits.
Sales of flip-chip type packages increased, mainly for PCs. Revenue from heat spreaders for CPUs, including for servers expanded due to strong demand. On the other hand, Sales of ceramic electro static chucks for semiconductor manufacturing equipment decreased due to the impact of investment restraints in the first half of fiscal year, despite remand was recovered significantly from the third quarter of fiscal year. Revenue from plastic BGA substrates and lead frames, including for memories declined. As a result of these factors, consolidated net sales for the period under review were 148,332 million yen (up 4.3% year on year).
Although profit and loss took an upturn with improved profitability driven by increased revenue of ceramic electro static chucks, flip-chip type packages and heat spreaders from the second half of the fiscal year, sales of ceramic electro static chucks, lead frames and other products declined significantly in the first half of the fiscal year; the cost of setting up the production lines for next-generation flip-chip type packages increased; and the yen exchange rate maintained a high level from the previous period. Such factors resulted in consolidated ordinary profit of 4,813 million yen (down 37.1% year on year).
Consolidated profit attributable to owners of the parent was 2,690 million yen (up 6.5% year on year).
