    摘要: A method and an apparatus are provided in which non-directional and directional metal (e.g. Ni) deposition steps are performed in the same process chamber. A first plasma is formed for removing material from a target; a secondary plasma for increasing ion density in the material is formed in the interior of an annular electrode (e.g. a Ni ring) connected to an RF generator. Material is deposited non-directionally on the substrate in the absence of the secondary plasma and electrical biasing of the substrate, and deposited directionally when the secondary plasma is present and the substrate is electrically biased. Nickel silicide formed from the deposited metal has a lower gate polysilicon sheet resistance and may have a lower density of pipe defects than NiSi formed from metal deposited in a solely directional process, and has a lower source/drain contact resistance than NiSi formed from metal deposited in a solely non-directional process.

    摘要: A MEM switch is described having a free moving element within in micro-cavity, and guided by at least one inductive element. The switch consists of an upper inductive coil; an optional lower inductive coil, each having a metallic core preferably made of permalloy; a micro-cavity; and a free-moving switching element preferably also made of magnetic material. Switching is achieved by passing a current through the upper coil, inducing a magnetic field in the coil element. The magnetic field attracts the free-moving magnetic element upwards, shorting two open wires and thus, closing the switch. When the current flow stops or is reversed, the free-moving magnetic element drops back by gravity to the bottom of the micro-cavity and the wires open. When the chip is not mounted with the correct orientation, gravity cannot be used. In such an instance, a lower coil becomes necessary to pull the free-moving switching element back and holding it at its original position.

    摘要: A method of forming silicide contacts for semiconductor devices includes subjecting a silicon containing semiconductor wafer to a degas treatment at an initial degas temperature of about 250 to about 400° C., transferring the semiconductor wafer from a degas chamber to a deposition chamber, depositing a nickel containing layer over the wafer following transfer of the wafer from the degas chamber to the deposition chamber, and annealing the semiconductor wafer so as to create silicide regions at portions on the wafer where nickel material is formed over silicon.

    摘要: A metal-insulator-metal (MIM) capacitor (242/252) structure and method of forming the same. A dielectric layer (214) of a semiconductor device (200) is patterned with a dual damascene pattern having a first pattern (216) and a second pattern (218). The second pattern (218) has a greater depth than the first pattern (216). A conductive layer (226) is formed over the dielectric layer (214) in the first pattern, and a conductive layer is formed over the conductive layer in the first pattern (216). A dielectric layer (232), conductive layer (234), dielectric layer (236) and conductive layer (238) are disposed over the conductive layer (226) of the second pattern (218). Conductive layer (234), dielectric layer (232) and conductive layer (226) form a first MIM capacitor (252). Conductive layer (238), dielectric layer (236) and conductive layer (234) form a second MIM capacitor (242) parallel to the first MIM capacitor (242).
