A method for fabricating one or more devices, e.g., integrated circuits. The method includes providing a substrate (e.g., silicon), which has a thickness of semiconductor material and a surface region. The substrate also has a cleave plane provided within the substrate to define the thickness of semiconductor material. The method includes joining the surface region of the substrate to a first handle substrate. In a preferred embodiment, the first handle substrate is termed a “thin” substrate, which provides suitable bonding characteristics, can withstand high temperature processing often desired during the manufacture of semiconductor devices, and has desirable de-bonding characteristics between it and a second handle substrate, which will be described in more detail below. In a preferred embodiment, the first handle substrate is also thick enough and rigid enough to allow for cleaving according to a specific embodiment.

A method of forming substrates, e.g., silicon on insulator, silicon on silicon. The method includes providing a donor substrate, e.g., silicon wafer. The method also includes forming a cleave layer on the donor substrate that contains the cleave plane, the plane of eventual separation. In a specific embodiment, the cleave layer comprising silicon germanium. The method also includes forming a device layer (e.g., epitaxial silicon) on the cleave layer. The method also includes introducing particles into the cleave layer to add stress in the cleave layer. The particles within the cleave layer are then redistributed to form a high concentration region of the particles in the vicinity of the cleave plane, where the redistribution of the particles is carried out in a manner substantially free from microbubble or microcavity formation of the particles in the cleave plane. That is, the particles are generally at a low dose, which is defined herein as a lack of microbubble or microcavity formation in the cleave plane. The method also includes providing selected energy to the donor substrate to cleave the device layer from the cleave layer at the cleave plane, whereupon the selected energy is applied to create a controlled cleaving action to remove the device layer from a portion of the cleave layer in a controlled manner.

A method for fabricating one or more devices, e.g., integrated circuits. The method includes providing a multi-layered substrate, which has a thickness of material (e.g., single crystal silicon) overlying a first debondable surface coupled to and overlying a second debondable surface.

A method and structures for manufacturing multi-layered substrates. The method includes providing a donor substrate, which has a first deflection characteristic. The donor substrate has a backside, a face, a cleave region, and a thickness of material defined between the cleave region and the face. The method includes bonding the face of the donor substrate to a face of the handle substrate. The method includes coupling a backing substrate to the backside of the donor substrate to form a multilayered structure. The backing substrate is adequate to cause the first deflection characteristic of the donor substrate to be reduced to a predetermined level. The predetermined level is a suitable deflection characteristic for the thickness of material to be transferred onto the face of a handle substrate. The method includes initiating a controlled cleaving process within a portion of the cleave region of the donor substrate to begin removal of the thickness of material from the donor substrate at a portion of the cleave region, while the backing substrate remains attached to the donor substrate to maintain at least the suitable deflection characteristic.

An open frame chassis has a top opening and a bottom opening permitting ambient air flow there through. A plurality of modules, each enclosing electrical components which are in thermal contact with a heat sink area of their corresponding module, and each of which can be inserted to an inserted position in the open frame chassis. When the modules are inserted into the open frame chassis, ambient air may flow from the bottom opening of the chassis across the heat sink area of each module to the top opening in order to passively cool the modules and the electrical components enclosed therein. The heat sink area has fins which are separated by a distance of 9 mm to 12 mm and have a height 10 mm to 20 mm. Key pins are associated with the electrical connectors of the chassis to guide the modules into place and prevent incorrect insertion of a different type of electrical module not corresponding to the electrical connection of the chassis for that slot. Guide pins are present on the corners of the modules to mate with guide holes in the chassis to secure the module to the open frame chassis and decrease vibration. Both sides of the chassis have side openings through which the fins of the modules inserted into the end slots of the chassis may be exposed. The power modules are inserted into the end slots. The chassis has an inverted connection at one end slot to accommodate identical power modules at both end slots such that the heat sink area always faces a side opening in the open frame chassis.

The invention provides a mobile device of an inner-pipeline detection device as well as a launching method and a receiving method of the inner-pipeline detection device by using the mobile device. The mobile device comprises a pallet, wherein the longitudinal length of the pallet is not less than the length of the inner-pipeline detection device, and the shape of the pallet enables the pallet to be capable of holding a part of the inner-pipeline detection device in the radial direction. According to the mobile device, the pipeline inner-detection device can be held by the non-magnetic pallet so that the inner-pipeline detection device can be separated from the internal wall of a launching-receiving spherical cylinder in the process of launching and receiving the inner-pipeline detection device. Therefore, the magnetic force generated between the inner-pipeline detection device and the launching-receiving spherical cylinder is reduced, the pipeline inner-detection device is conveniently launched to a predetermined position in the launching-receiving spherical cylinder, and then the position of the inner-pipeline detection device can be kept with only extracting the pallet, thereby greatly reducing the possibility of damageing the inner-pipeline detection device.

A disposable hand tool for easily smoothing or spreading of material made for the filling of gaps or the sealing of two adjacent surfaces. The tool consists of a depressor made of plastic or cut wood surround on one end by cellular foam forming the smoothing head, while the depressor extends beyond the foam to form the handle. The depressor provides necessary reinforcement and stability to the foam, in order that when the surface of the cellular foam makes contact with the caulking material, enough rigidity is provided to transfer pressure as applied variably by the user with the handle to smooth the caulking material, but the pliability of the foam accommodates and flexes to variances in the surfaces being joined or filled by the caulking material. When finished using, the tool can be disposed of, or in some instances cleaned using appropriate process for removal of excess material being smoothed, and reused.
