Abstract: Backup power for the volatile cells (12) of a memory array is provided by an auxiliary backup battery power source which is automatically connected to the memory array power input node (14) in response to loss of power from the primary external power source. Primary operating current for the volatile cells (12) of the memory array is conducted through a first field effect transistor switch (20) having its gate (20 G) and drain (20 D) electrically connected to an external power input pin (18) and its source (20 S) electrically connected to the memory array power input node (14). Auxiliary operating current for the volatile cells (12) of the memory array is provided by a second field effect transistor switch (34) having its drain (34 D) and gate (34 G) electrically connected to an external control signal input pin (26) and its source (34 S) electrically connected to the memory array power input node (14). The first transistor switch (20) automatically establishes a conductive path from the external power input pin (18) to the memory array power input node (14) in response to the voltage of the power input pin (18) relative to the voltage of the memory array power input node (14) rising above the threshold voltage of the transistor (20), and automatically interrupts the conductive path in response to the voltage of the external power input pin (18) relative to the voltage of the memory array power input node (14) falling below the threshold voltage. The second transistor switch (34) automatically establishes and interrupts a conductive path from the control signal input pin (26) to the memory array input power input node (14) in response to the rise and fall of voltage on the control signal input pin (26) relative to the voltage of the memory array power input node (14).

Abstract: PURPOSE:To make it possible to bond a Cu ball to a reliable IC or LSI by a method wherein the copper ball is deformed in such a way that one of crystal grains on the peripheral part of the copper ball right over the interface of a joint part makes an angle of 30 degrees or less with a semiconductor integrated circuit chip and is bonded to the IC or LSI. CONSTITUTION:In the joint part between a Cu ball and an Al electrode on an Si chip, the Cu ball is deformed in such a way that at least one of crystal grains 2 on the peripheral part of the Cu ball 1 right over the interface of the joint part makes an angle theta of 30 degrees or less with the Si chip and is bonded. After the texture of the Cu ball on the bonding interface of the Cu ball is polished in parallel to the chip, the crystal grains are contrived in such a way that their average crystal grain diameter becomes 15 mum or less. In such a way, when the ball is formed by short-circuit discharge using a Cu wire of a high purity of 99.999 % or more in the mixed inert gas of Ar and H2 gases, the rate of solidification is controlled. Thereby, the texture is controlled and the ball is softened to prevent a failure of bonding.

Abstract: An apparatus and method of contacting a liquid with different gases sequentially in separate mass transfer zones within a single vessel, the mass transfer zones operatively connected in liquid communication with each other, including intimately contacting the liquid with a first process gas in cocurrent flow in a first mass transfer zone to effect mass transfer between the first liquid and the process gas, and introducing the liquid into a second mass transfer zone with a second gas, different from the first gas, in cocurrent flow with the second liquid, thereby effecting mass transfer between the second liquid and the second gas. The rate of flow of the liquid from said first mass transfer zone to second mass transfer zone and recirculation to the first mass transfer zone is motivated by the difference in density of the contents of the liquid phase portion of each mass transfer zone and a following liquid downcomer or flow channel connecting it to the next sequential mass transfer zone, such that after passing through the last mass transfer zone, the liquid recirculates to the first mass transfer zone. The apparatus and method are ideally suited to carrying out the process of hydrogen sulfide removal from gases by means of an air-regenerated liquid redox catalyst, such as chelated iron. <IMAGE>
