摘要:
A conversion coating, predominantly consisting of tin phosphate, can be deposited on steel or tin plated steel surfaces by contact with a solution containing phosphate ions, tin ions, an oxidizing agent such as chlorate, and a chelating agent for the tin ions, the latter to prevent the rapid loss of tin from the solution that otherwise would occur. A coating that confers excellent resistance to corrosion in hot water is formed on drawn and ironed thinly tin plated cans.

First semiconductor integrated circuits and second semiconductor integrated circuits arranged over a first substrate so that each of the second semiconductor integrated circuits is adjacent to one of the first semiconductor integrated circuits are transferred to additional substrates through multiple transfer operations. After the first semiconductor integrated circuits and the second semiconductor integrated circuits formed over the first substrate are transferred to the additional substrates (a fourth substrate and a fifth substrate) respectively, the circuits are divided into a semiconductor device corresponding to each semiconductor integrated circuit. The first semiconductor integrated circuits are arranged while keeping a distance from each other over the fourth substrate, and the second semiconductor integrated circuits are arranged while keeping a distance from each other over the fifth substrate. Thus, a large division margin of each of the fourth substrate and the fifth substrate can be obtained.

摘要:
In the production process where an ordered article and a forecast production article are mixed, parameters for defining production priority of each article are preset while assuming a case where the demand exceeds the available production capability, and priority is given to an article which must be produced first within the range of available production capability according to the marginal stock rate of each article. The marginal stock rate is determined by (effective stock amount/necessary stock amount) for a forecast production article. As for the ordered production article, a stock sufficient for delivery is required at the time of shipment. Accordingly, stock of that quantity (demand take-in amount) can be regarded as the necessary amount of stock while the currently completed products can be regarded as the effective stock amount. Thus, the marginal stock rate (effective stock amount/demand take-in amount) can be indexed.

A plurality of first semiconductor integrated circuits, a plurality of second semiconductor integrated circuits each of which is arranged to be adjacent to one of the first semiconductor integrated circuits, a plurality of third semiconductor integrated circuits each of which is arranged to be adjacent to one of the first semiconductor integrated circuits and one of the second semiconductor integrated circuits, and a plurality of fourth semiconductor integrated circuits each of which is arranged to be adjacent to one of the first semiconductor integrated circuits, one of the second semiconductor integrated circuits, and one of the third semiconductor integrated circuits are formed over a first substrate. The first semiconductor integrated circuits are transferred to a second substrate. A first protective layer is formed to cover the first semiconductor integrated circuits and a surface of the second substrate in the periphery of the first semiconductor integrated circuits. The second substrate and the first protective layer are divided so that the plurality of the first semiconductor integrated circuits is divided into individual pieces and part of the second substrate remains in the periphery of the first semiconductor integrated circuits. Accordingly, a semiconductor device having the first semiconductor integrated circuit is manufactured.
