Toshiba has announced a reorganization of its semiconductor production facilities in Japan, in an effort to reinforce the operating structure and profitability of the discrete, analog and imaging IC businesses.

The reorganization will concentrate the front- and back-end production processes of six discrete semiconductor facilities into three major facilities: Hijimeji Operations-Semiconductor (Ibo-gun, Hyogo prefecture); Kaga Toshiba Electronics Corporation (Nomi, Ishikawa prefecture); and Buzen Toshiba Electronics Corporation (Buzen, Fukuoka prefecture).

In parallel with this, Toshiba will phase out production at three facilities during the first half fiscal year of 2012: Kitakyushu Operations (Kitakyushu, Fukuoka prefecture) and Hamaoka Toshiba Electronics Corporation (Omaezaki, Shizuoka prefecture), which carry out front-end production of optical semiconductors; and Toshiba Components Co., Ltd. (Mobara, Chiba prefecture), an assembly facility for power semiconductors.

Toshiba believes that the concentration of domestic production of discrete products at three major facilities will strengthen the company's cost competitiveness and help it focus on higher value added products.

Following the reorganization, Himeji Semiconductor Operations will continue to strengthen its function as a development center for power semiconductors and small signal devices. Kaga Toshiba Electronics Corporation, as a main facility for the power semiconductor front-end process, will increase capacity on its current 8-inch wafer product line and expand production to include the front-end process for optical semiconductors.

Buzen Toshiba will assume the new function of development center for assembly and packaging technologies for optical semiconductors. It will increase consignment to overseas pursuing cost competitiveness, and its production will be limited to focused products.

In the analog and imaging IC businesses, Toshiba will continue to promote a shift to production on larger wafers to improve manufacturing efficiency and cost competitiveness. Oita Operations will halve production on its 6-inch wafer line during the first half of fiscal year 2012.

Toshiba has been implementing a series of measures to restructure and strengthen its discrete and analog and imaging IC businesses, including accelerating the transfer of assembly and test operations to overseas facilities, outsourcing, shifting to larger diameter wafer production lines and halving its product line-up.

Regular employees at the affected facilities will, in principle, be redeployed within Toshiba Group.

In addition to the above, Toshiba is responding to the current economic slowdown and fall in demand for consumer products, most notably for PCs and TVs in Europe and the United States, by cutting production at some of its semiconductor facilities from late November 2011 to early January 2012.

Production will be affected at six facilities in all: three Toshiba Corporation facilities - Oita Operations, which produces analog semiconductors and image sensors; Himeji Operations-Semiconductor, which produces discrete semiconductors; and Kitakyushu Operations, which produces optical semiconductor devices - and three Toshiba Group companies, Iwate Toshiba Electronics, which produces ASICs and MCUs; and Kaga Toshiba Electronics and Hamaoka Toshiba electronics, which produces discrete semiconductors.

"Temporary reductions in working and operating hours will give Toshiba the flexibility it needs to respond to the fall off in demand for consumer products," the company said in a statement. Toshiba will monitor the market and demand to make decisions on its operations and production levels after the turn of the year.
