    摘要: Methods are provided of fabricating compound nitride semiconductor structures. A group-III precursor and a nitrogen precursor are flowed into a processing chamber to deposit a first layer over a surface of a first substrate with a thermal chemical-vapor-deposition process. A second layer is deposited over a surface of a second substrate with the thermal chemical-vapor-deposition process using the first group-III precursor and the first nitrogen precursor. The first and second substrates are different outer substrates of a plurality of stacked substrates disposed within the processing chamber as a stack so that the first and second layers are deposited on opposite sides of the stack. Deposition of the first layer and deposition of the second layer are performed simultaneously.

    摘要: The present invention provides an apparatus and a method for variable size pages using fixed size TLB (Translation Lookaside Buffer) entries. In one embodiment, an apparatus for variable size pages using fixed size TLB entries includes a first TLB for fixed size pages and a second TLB for variable size pages. In particular, the second TLB stores fixed size TLB entries for variable size pages. Further, in one embodiment, an input of an OR device is connected to the second TLB to provide a cost-effective and efficient implementation for translating linear addresses to physical addresses using fixed size TLB entries stored in the second TLB.

    摘要: In accordance with the present invention, improved methods for reducing the dislocation density of nitride epitaxial films are provided. Specifically, an in-situ etch treatment is provided to preferentially etch the dislocations of the nitride epitaxial layer to prevent threading of the dislocations through the nitride epitaxial layer. Subsequent to etching of the dislocations, an epitaxial layer overgrowth is performed. In certain embodiments, the etching of the dislocations occurs simultaneously with growth of the epitaxial layer. In other embodiments, a dielectric mask is deposited within the etch pits formed at the dislocations prior to the epitaxial layer overgrowth.

A layer is deposited over the substrate with a thermal chemical-vapor-deposition process using the precursors. The substrate is transferred to a transfer chamber where a temperature and a curvature of the layer are measured. The substrate is then transferred to a second processing chamber where a second layer is deposited.

    摘要: Methods are disclosed for fabricating a compound nitride semiconductor structure. An amorphous buffer layer that includes nitrogen and a group-III element is formed over a substrate disposed within a substrate processing chamber at a first temperature. The temperature within the chamber is increased to a second temperature at which the amorphous buffer layer coalesces into crystallites over the substrate. The substrate is exposed to a corrosive agent to destroy at least some of the crystallites. A crystalline nitride layer is formed over the substrate at a third temperature using the crystallites remaining after exposure to the corrosive agent as seed crystals. The third temperature is greater than the first temperature. The crystalline nitride layer also includes nitrogen and a group-III element.
