Abstract: An electromagnetic wave irradiation apparatus and methods to bond unbonded areas in a bonded pair of substrates are disclosed. The unbonded areas between the substrates are eliminated by thermal activation in the unbonded areas induced by electromagnetic wave irradiation having a wavelength selected to effect a phonon or electron excitation. A first substrate of the bonded pair of substrates absorbs the electromagnetic radiation and a portion of a resulting thermal energy transfers to an interface of the bonded pair of substrates at the unbonded areas with sufficient flux to cause opposite sides the first and second substrates to interact and dehydrate to form a bond (e.g., Si—O—Si bond).

Abstract: The present invention relates to a process for forming microstructures on a substrate. A plating surface is applied to a substrate. A first layer of photoresist is applied on top of the plating base. The first layer of photoresist is exposed to radiation in a pattern to render the first layer of photoresist dissolvable in a first pattern. The dissolvable photoresist is removed and a first layer of primary metal is electroplated in the area where the first layer of photoresist was removed. The remainder of the photoresist is then removed and a second layer of photoresist is then applied over the plating base and first layer of primary metal. The second layer of photoresist is then exposed to a second pattern of radiation to render the photoresist dissolvable and the dissolvable photoresist is removed. The second pattern is an area that surrounds the primary structure, but it does not entail the entire substrate. Rather it is an island surrounding the primary metal.

Abstract: A pressure sensor having a flexible membrane which is moved by an external force, such as pressure from an air flow. The flexible membrane extends over a semiconductor frame having an opening, such that a portion of the flexible membrane extends over the semiconductor frame, and a portion of the flexible membrane extends over the opening. An inherent tensile stress is present in the membrane. One or more strain gage resistors are formed on the portion of the membrane which extends over the opening of the semiconductor frame. The membrane deforms in response to an externally applied pressure. As the membrane deforms, the strain gage resistors elongate, thereby increasing the resistances of these resistors. This change in resistance is measured and used to determine the magnitude of the external pressure. In one embodiment, a Wheatstone bridge circuit is used to translate the change in resistance of the strain gage resistors into a differential voltage.

Abstract: A fiber-optic microswitch is disclosed that includes a flexible mirror positioning structure including an outer fixed frame, a movable platform upon which a mirror is formed, and two or more resilient support members (e.g., monocrystalline silicon springs or torsion beams) connecting the movable platform to the fixed frame. Stationary fibers are mounted over the mirror. An electromagnetic drive mechanism is provided for positioning the movable platform relative to the fixed frame. The electromagnetic drive mechanism includes one or more coils formed on a drive substrate mounted under the monocrystalline structure, and one or more pole pieces that are mounted on the movable platform. Currents are selectively applied to the coils to generate attractive electromagnetic forces that pull the pole pieces, thereby causing the movable platform to move (e.g., tilt) relative to the fixed frame, thereby selectively directing light from one fiber to another. Various monocrystalline structures are disclosed.

Abstract: A micro-sensor having have a flexible monocrystalline structure that is moved by an external force. In one embodiment, one or more pole tips are mounted on the monocrystalline structure. The monocrystalline structure is suspended over one or more planar coils such that each pole tip is suspended over a corresponding planar coil. As the monocrystalline structure moves in response to the external force, the pole tips are moved in the coils, thereby changing the inductance or inducing a voltage in the coils. In another variation, a micro-switch includes a lower structural member having a pattern of raised spacer pads that laterally surround a plurality of contact pads. The lower structural member is joined to an upper structural member that includes a frame, a platform located in the frame and a plurality of spring elements which connect the frame to the platform. The upper structural member has a conductive layer formed on its planar lower surface.

Abstract: A micro-switch having a flexible conductive membrane which is moved by an external force, such as pressure from an air flow, to establish a connection between contact pads. The conductive membrane is stretched over one or more spacer pads to introduce deformation in the conductive membrane, thereby improving the accuracy and repeatability of the micro-switch. The spacing between the contact pads and the conductive membrane is precisely controlled by controlling the height difference between the spacer pads and the conductive pads. This height difference is determined by one or more precisely controlled etch operations.

Abstract: A micro-relay has a flexible monocrystalline structure which is moved by an electromagnetic force to establish a connection between relay contact elements. The micro-relay includes a substrate having a magnetic pathway and one or more coils located over the magnetic pathway. A first contact pad is coupled to the substrate. The monocrystalline structure is suspended over the substrate. A second contact pad and pole pieces are coupled to the monocrystalline structure such that the second contact pad is positioned over the first contact pad, and the pole pieces are located over the coils. A current is applied to the coils to generate an electromagnetic force which flexes the monocrystalline structure toward the substrate, thereby causing the second contact pad to touch the first contact pad. In one embodiment, the coils include insulating spacers located adjacent to the innermost and outermost traces to prevent shorting.
