摘要： A hinge type MEMS switch that is fully integratable within a semiconductor fabrication process, such as a CMOS, is described. The MEMS switch constructed on a substrate consists of two posts, each end thereof terminating in a cap; a movable conductive plate having a surface terminating in a ring in each of two opposing edges, the rings being loosely connected to guiding posts; an upper and lower electrode pairs; and upper and lower interconnect wiring lines connected and disconnected by the movable conductive plate. When in the energized state, a low voltage level is applied to the upper electrode pair, while the lower electrode pair is grounded. The conductive plate moves up, shorting two upper interconnect wirings lines. Conversely, the conductive plate moves down when the voltage is applied to the lower electrode pair, while the upper electrode pair is grounded, shorting the two lower interconnect wiring lines and opening the upper wiring lines. The MEMS switch thus formed generates an even force that provides the conductive plate with a translational movement, with the displacement being guided by the two vertical posts.

摘要： A method of making a diffusion barrier for a interconnect structure. The method comprises: providing a conductive line in a bottom dielectric trench; depositing a sacrificial liner on the cap layer; depositing an interlayer dielectric; forming a trench and a via in the top interlayer dielectric; and removing a portion of the cap layer and the sacrificial layer proximate to the bottom surface of the via. The removed portions of the cap layer and sacrificial layer deposit predominantly along the lower sidewalls of the via. The conductive line is in contact with a cap layer, and the sacrificial layer is in contact with the cap layer. The invention is also directed to the interconnect structures resulting from the inventive 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： In one embodiment, Hexagonal tiles encompassing a large are divided into three groups, each containing ⅓ of all hexagonal tiles that are disjoined among one another. Openings for the hexagonal tiles in each group are formed in a template layer, and a set of self-assembling block copolymers is applied and patterned within each opening. This process is repeated three times to encompass all three groups, resulting in a self-aligned pattern extending over a wide area. In another embodiment, the large area is divided into rectangular tiles of two non-overlapping and complementary groups. Each rectangular area has a width less than the range of order of self-assembling block copolymers. Self-assembled self-aligned line and space structures are formed in each group in a sequential manner so that a line and space pattern is formed over a large area extending beyond the range of order.

摘要： A first nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running along a first direction is formed from first self-assembling block copolymers within a first layer. The first layer is filled with a filler material and a second layer is deposited above the first layer containing the first nanoscale nested line structure. A second nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running in a second direction is formed from second self-assembling block copolymers within the second layer. The composite pattern of the first nanoscale nested line structure and the second nanoscale nested line structure is transferred into an underlayer beneath the first layer to form an array of structures containing periodicity in two directions.
