    摘要： A method of forming an isolation region using porous silicon and a related structure are disclosed. One embodiment of the method may include forming a collector region; forming a porous silicon region in the collector region; forming a crystalline silicon intrinsic base layer over the collector region, the intrinsic base layer extending over a portion of the porous silicon region to form an extrinsic base; and forming an isolation region in the porous silicon region. The method is applicable to forming an HBT having a structure including a crystalline silicon intrinsic base extending beyond a collector region and extending over an isolation region to form a continuous intrinsic-to-extrinsic base conduction path of low resistance. The HBT has improved performance by having a smaller collector to intrinsic base interface and larger intrinsic base to extrinsic base interface.

    摘要： A cost efficient and manufacturable method of fabricating strained semiconductor-on-insulator (SSOI) substrates is provided that avoids wafer bonding. The method includes growing various epitaxial semiconductor layers on a substrate, wherein at least one of the semiconductor layers is a doped and relaxed semiconductor layer underneath a strained semiconductor layer; converting the doped and relaxed semiconductor layer into a porous semiconductor via an electrolytic anodization process, and oxidizing to convert the porous semiconductor layer into a buried oxide layer. The method provides a SSOI substrate that includes a relaxed semiconductor layer on a substrate; a high-quality buried oxide layer on the relaxed semiconductor layer; and a strained semiconductor layer on the high-quality buried oxide layer. In accordance with the present invention, the relaxed semiconductor layer and the strained semiconductor layer have identical crystallographic orientations.

    摘要： A method of controlling the nucleation rate (i.e., incubation time) of dissimilar materials in an epitaxial growth chamber that can favor high growth rates and can be compatible with low temperature growth is provided. The nucleation rate of dissimilar materials is controlled in an epitaxial growth chamber by altering the nucleation rate for the growth of a given material film, relative to single crystal growth of the same material film, by choosing an appropriate masking material with a given native nucleation characteristic, or by modifying the surface of the masking layer to achieve the appropriate nucleation characteristic. Alternatively, nucleation rate control can be achieved by modifying the surface of selected areas of a semiconductor substrate relative to other areas in which an epitaxial semiconductor material will be subsequently formed.

    摘要： A method of forming a strained semiconductor-on-insulator (SSOI) substrate that does not include wafer bonding is provided. In this disclosure a relaxed and doped silicon layer is formed on an upper surface of a silicon-on-insulator (SOI) substrate. In one embodiment, the dopant within the relaxed and doped silicon layer has an atomic size that is smaller than the atomic size of silicon and, as such, the in-plane lattice parameter of the relaxed and doped silicon layer is smaller than the in-plane lattice parameter of the underlying SOI layer. In another embodiment, the dopant within the relaxed and doped silicon layer has an atomic size that is larger than the atomic size of silicon and, as such, the in-plane lattice parameter of the relaxed and doped silicon layer is larger than the in-plane lattice parameter of the underlying SOI layer. After forming the relaxed and doped silicon layer on the SOI substrate, the dopant within the relaxed and doped silicon layer is removed from that layer converting the relaxed and doped silicon layer into a strained (compressively or tensilely) silicon layer that is formed on an upper surface of an SOI substrate.
