Inventor: OH YUN SEOK
IPC: G11C5/14
Filed: 2001-06-26
Abstract: PURPOSE: A semiconductor device using a deep power down mode is provided to reduce standby current by stopping an internal voltage and an external voltage when a chip is deselected. CONSTITUTION: A semiconductor circuit portion(10) uses an external voltage(Vext). A PMOS transistor(P1) transmits the external voltage(Vext) to the semiconductor circuit portion(10) when a deep power down signal(Power down) is a 'logic low' level. Accordingly, the external voltage(Vext) is directly applied to the semiconductor circuit portion(10). Namely, if a chip is selected, the PMOS transistor(P1) is turned on to supply the external voltage(Vext) to the semiconductor circuit portion(10) since the deep power down signal(Power down) becomes 'logic low'. In addition, the chip is deselected, the PMOS transistor(P1) is turned off to stop the external voltage(Vext) supplied to the semiconductor circuit portion(10) since the deep power down signal(Power down) becomes 'logic high'.

Abstract: PURPOSE: A method for manufacturing high purity iron target in which the content of impurities such as copper is reduced is provided. CONSTITUTION: Iron containing impurities such as copper is dissolved into a solution of hydrochloric acid to prepare an aqueous solution of iron chloride in which the concentration of hydrochloric acid is 0.1 to 6 kmol/m¬3. Next iron is charged to the aqueous solution of iron chloride and is stirred while an inert gas is blown therein to convert copper contained in the aqueous solution of iron chloride into univalent ions and further to convert iron into bivalent ions. Successively, the aqueous solution of iron chloride is flowed into a column packed with anion-exchange resin. At this time, univalent copper to ions is adsorbed on the anion exchange resin, however, bivalent iron ions are not adsorbed thereon. Thus, copper can be separated from the aqueous solution of iron chloride. After that, the aqueous solution of iron chloride is vaporized, dried and oxidized and is then heated in hydrogen atmosphere to generate iron.
