A solid electrolytic capacitor and method for making the capacitor are provided. The capacitor includes a porous anode body, an anode foil, a dielectric, a cathode, and anode and cathode terminations. The foil is disposed on a planar surface of the anode body, and both comprise a valve metal. Further, the dielectric overlies at least a portion of the anode body, and the dielectric is also formed within the anode body. The cathode overlies at least a portion of the dielectric that overlies the anode body and includes a solid electrolyte, where at least a portion of a lower surface of the foil is free of both the dielectric and the solid electrolyte. In addition, the anode termination is electrically connected to the portion of the lower surface of the foil that is free of both the dielectric and the solid electrolyte, and the cathode termination is electrically connected to the solid electrolyte.

A solid electrolytic capacitor and method for making the capacitor are provided. The capacitor includes a sintered porous anode body formed from a valve metal, a metallic physical vapor deposition (PVD) layer disposed directly on a planar surface of the anode body, a dielectric, a cathode, and anode and cathode terminations. The dielectric overlies at least a portion of the anode body and is also formed within the anode body. The cathode overlies at least a portion of the dielectric that overlies the anode body and includes a solid electrolyte, and a portion of a lower surface of the metallic PVD layer is free of both the dielectric and solid electrolyte. The anode termination is electrically connected to the portion of the lower surface of the metallic PVD layer that is free of both the dielectric and solid electrolyte, and the cathode termination is electrically connected to the solid electrolyte.

A solid electrolytic capacitor and method for making the capacitor are provided. The capacitor includes a sintered porous anode body; a sintered anode substrate; a dielectric that overlies at least a portion of the anode body and at least a portion of the anode substrate and that is also formed within at least a portion of the anode body; a solid electrolyte cathode overlying at least a portion of the dielectric that overlies the anode body; an anode termination that is electrically connected to the anode substrate; and a cathode termination that is electrically connected to the solid electrolyte. The anode body is disposed on a planar surface of the anode substrate, and both the anode body and substrate are formed from a powder of a valve metal composition. Further, the anode substrate is hermetic and impermeable to liquids.

A data storage device comprises a first substrate and a second substrate, wherein at least the first substrate has defined thereon a plurality of pits and lands covered by a reflective material; and a bonding layer between the first and second substrates including a reactive agent that interferes with the passage of light in response to predetermined stimulus. In another embodiment, an optically-readable storage media, comprises a substrate having encoded data stored thereon, a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range, and a second reactive agent that, in response to predetermined stimulus, degrades the readability of the encoded data.

A system and method cure a resin disposed between a combination of a top substrate and a bottom substrate with low power. One of the top and bottom substrates includes metallized data pits. Resin-curing light is directed at sides of the data pits.

Method of forming bonded storage disks with low power light assembly

A system and method to maintain concentricity of a center hole of a top substrate and of a bottom substrate in a bonded storage disk manufacturing system. A first device holds a coaxial arrangement of a top and bottom substrate around a first arbor. A second device holding the arrangement in a coaxial arrangement around a second arbor. One of the first and second arbors is fixed to its associated device and the other is movable in response to urging from the one arbor so that the arrangement maintains concentricity.

Method for maintaining concentricity of a combination of a top and bottom substrate during the assembly of a bonded storage disk

A system and method cures a combination of a top and a bottom substrate with a resin disposed in-between. A cure device inherently warps the combination in one direction as a result of a curing operation that the cure device performs on the combination. A temperature gradient inducing device is disposed closer to one of the top and bottom substrates to create a temperature gradient between the top and bottom substrate and thereby warp the combination in a direction opposite to the one direction.

System for forming bonded storage disks with low power light assembly

An improved substrate and stamper holder and method of forming substrates are disclosed. According to a preferred embodiment of the invention, a substrate for a DVD has a moat with a capillary barrier shape. Under one embodiment, the moat has a region with an abrupt outer diameter transition. One embodiment has the outer diameter transition at approximately at a right angle relative to a registering surface of the substrate. Another embodiment of the invention provides a wider moats. The improvements reduce the likelihood of resin wicking past the moats.

A system and method distribute a resin disposed between a top substrate and a bottom substrate. Each substrate has a center hole, and the top and bottom substrates and the resin define an interior region. A top substrate assembly forms a seal over the center hole of the top substrate and creates a vacuum at the interior region. A bottom substrate assembly receives the top and bottom substrates with the resin disposed in-between. A spinning assembly causes the top and bottom substrates to spin according to a predetermined spin profile.

A system and method dispense resin between substrates. A top substrate device holds a top substrate concave up. A bottom substrate device holds a bottom substrate concave down. A resin dispensing device has a needle and dispenses a trajectory of resin defined by an arc having a tangent that touches a tangent of a concave-up-shaped top substrate. The top substrate device may be arranged to include a dampening mechanism to cause a dampened release of the top substrate. Moreover, the top substrate device may be arranged to hold a top substrate so that the top substrate has a continuous concave-up shape extending from a center portion of the top substrate to its outer diameter, and the bottom substrate device may be arranged to hold a bottom substrate so that the bottom substrate has a continuous concave-down shape extending from a center portion of the bottom substrate to its outer diameter.
