Japan shuts down the semiconductors of the Hamaoka Nuclear Power Plant

The Japanese government has asked to shut down the Hamaoka nuclear power plant to make Japanese semiconductor material suppliers in the resumption of work worse. The industry pointed out that Japan's lack of electricity in the summer will lead to lower than expected material supply, including silicon wafers, silver plastic, epoxy resin and other semiconductor material gains established, the second and third quarter of the increase may reach 20 to 30%.

Japan closed the Hamaoka nuclear power plant, and Chubu Electric could not use surplus power to support summer electricity in the Kanto and northeast.

Huang Jianeng, chairman of Taiwan's leading packaging material supplier, Huadian Electric, said that the material shortage problem that has emerged after the Japan earthquake has already surfaced, and the cost of materials will rise in an all-round way. If the benchmark is Japanese currency, it will increase prices by at least 10 to 20%. Some of the material price increases are already in progress, including silver glue, epoxy resin, lead frames, and so on.

Due to the severe damage to the Japanese supplier's equipment during the earthquake, during the next resumption of work, they encountered summer power restrictions, and the supply side has already experienced problems. Therefore, price increases are inevitable.

According to industry insiders, in terms of the semiconductor production chain, the upstream wafer fab is the first to solve the problem of silicon wafers being out of stock. Although SUMCO, MEMC, and Shin-Etsu Semiconductor have all resumed, summer The power cut problem is likely to be caused by the closure of the Hamaoka nuclear power plant by Chubu Power, which will result in tighter power supply in the Kanto and Tohoku areas.

In order to fear that there will not be enough supply of silicon wafers after the peak season in the second half of the year, semiconductor manufacturers in Taiwan, Japan, and South Korea will actively take orders to pull goods, and the price of silicon wafers will naturally rise, and the industry will evaluate the second quarter and third quarter gains. Fear up to 10 to 15%.

As for the problems faced by the packaging plant, the main problem is the shortage of critical chemical materials. In addition to the previous supply shortage of BT resin, the key includes silver paste, epoxy resin, lead frame, solder mask, etc. The material supplier also failed to fully recover its production capacity due to more upstream chemical materials. Until the end of June, it could not return to the pre-earthquake supply.

In the third quarter of the summer, after the peak period of electricity consumption, the Japanese government demanded that Kanto and Northeastern regions need to reduce their electricity consumption by 20 to 25%. Now that Central Power is unable to support excess electricity, the supply of chemical materials will naturally not be able to produce full capacity. Therefore, the price increase of packaging materials is now in progress, and the price increase in the second quarter to the third quarter is as high as 20 to 30%.
