摘要： In a high-performance semiconductor integrated circuit, the standby current is reduced by preventing current leakage in a semiconductor integrated circuit device, for example, the memory cell of an SRAM. A gate electrode G is formed on semiconductor substrate 1 and n+-type semiconductor regions 17 (source/drain regions) are formed in the semiconductor substrate on both sides of this gate electrode. Within the same apparatus and under near-vacuum conditions, a depth of 2.5 nm or less is etched away from the surfaces of the source/drain regions and gate electrode, a film of Co is then formed on the source/drain regions, and thermal processing is applied to form CoSi2 layer 19a. As a result, current leakage in the memory cell can be prevented and this method can be applied to semiconductor integrated circuit devices that have low current consumption or are battery-driven.

摘要： Provided is a battery pack capable of reducing the number of terminals of a battery protection IC. When a battery (15) enters an overdischarge state, a temperature switch IC (12) included in a battery pack (10) monitors a voltage of a voltage monitoring terminal (VM2) provided to an external connection terminal (EB−), rather than a voltage of a terminal of the battery protection IC (11) for use in communication with the temperature switch IC (12), and then shuts down. Therefore, the battery protection IC (11) included in the battery pack (10) does not require an additional terminal for use in communication with the temperature switch IC (12).
