A method of manufacture for a semiconductor device is disclosed. The method includes providing a semiconductor stack structure that includes a device terminal of a semiconductor device, and having a first surface and a buried oxide (BOX) layer attached to a wafer handle. Another step includes disposing a polymeric layer that includes a polymer and an admixture that increases thermal conductivity of the polymer onto the first surface of the semiconductor stack structure. Another step involves removing the wafer handle from the BOX layer to expose a second surface of the semiconductor stack structure, and yet another step involves removing a portion of the semiconductor stack structure to expose the device terminal.

Method of manufacture for a semiconductor device

A semiconductor device that does not produce nonlinearities attributed to a high resistivity silicon handle interfaced with a dielectric region of a buried oxide (BOX) layer is disclosed. The semiconductor device includes a semiconductor stack structure with a first surface and a second surface wherein the second surface is on an opposite side of the semiconductor stack structure from the first surface. At least one device terminal is included in the semiconductor stack structure and at least one electrical contact extends from the second surface and is electrically coupled to the at least one device terminal. The semiconductor stack is protected by a polymer disposed on the first surface of the semiconductor stack. The polymer has high thermal conductivity and high electrical resistivity.

Silicon-on-plastic semiconductor device and method of making the same

A chemical mechanical polishing (CMP) process using a chemically active slurry having a polarity selected to affect the relative oxidation rates of respective crystalline planes of a polycrystalline surface being polished. The slurry polarity is controlled to equilibrate the material removal rates from the respective crystalline planes during the CMP process. A polar solute may be added to a base solvent to achieve the desired polarity. A CMP process for a tungsten film may utilize a water-based slurry containing an abrasive agent, an oxidizing agent, and a solute having a polarity less than that of water. The abrasive agent may be colloidal silica, the oxidizing agent may be hydrogen peroxide, and the solute may be benzene.

A manufacturing method using a modular substrate-based processing scheme for producing semiconductor devices, provides multiple modular processing units which may be arranged together to form any of various cohesive processing units or individually or sequentially processed through standard semiconductor processing equipment. The cohesive processing units are processed unitarily providing for multiple modular processing units to be processed simultaneously. The modular processing units may be formed of a thick semiconductor substrate or a semiconductor substrate mounted on a further substrate such as a ceramic material. The modular processing units may each contain ribs, grooves, posts or other features to aid in handling and placement of the individual units.

Semiconductor manufacturing using modular substrates

A method and apparatus for minimizing the surface contamination of semiconductor wafers ( ) during the semiconductor device manufacturing process. Semiconductor wafers ( ) are stored in a storage cassette ( ) with their face sides ( ) facing downward and their back sides ( ) facing upward. Particulate contamination present on the back sides of the wafers is thereby secured to the wafers by the force of gravity, and the faces of the wafers are shielded from falling debris. An automated wafer handling device ( ) is provided with a rotary joint ( ) to accomplish the wafer flipping motion before inserting a wafer into a cassette and after removing the wafer from the cassette.

A reflective lens with at least one curved surface formed of polycrystalline material. In one embodiment, a lens structure includes a substrate having a surface of predetermined curvature and a film formed along a surface of the substrate with multiple individual members each having at least one similar orientation relative to the portion of the substrate surface adjacent the member such that collectively the members provide predictable angles for diffraction of x-rays generated from a common source. A system is also provided for performing an operation with x-rays. In one embodiment, a system includes a source for generating the x-rays, a polycrystalline surface region having crystal spacing suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, and transmitting the reflected x-rays to a reference position. An associated method includes providing x-rays to polycrystalline surface region having crystal spacings suitable for reflecting a plurality of x-rays at the same Bragg angle along the region, transmitting the reflected x-rays to a reference position and positioning a sample between the surface region and the reference position so that the x-rays are transmitted through the sample.
