摘要： Low temperature silicon-on-insulator wafer bonding using a silicide bond formation reaction. Dielectric isolation with silicon dioxide, diamond, silicon-nitride, and so forth yields buried resistors under trench isolated silicon islands. Buried dielectrics can be thermally susceptible films like diamond due to the low temperature of the bonding silicidation reaction. Bonding silicides also provide thermal dissipating layer between a buried diamond layer and a handle wafer for good overall thermal conductivity. Bonding silicides also act as diffusion barriers.

摘要： In a method for forming a bonded semiconductor-on-insulator substrate for the fabrication of semiconductor devices and integrated circuits, a surface of a wafer of a monocrystalline semiconductor material is implanted with ions of the semiconductor material a to a selected depth in the wafer to form, adjacent to the surface, an amorphous layer of the semiconductor material. The layer of amorphous semiconductor material extends to a substantially planar zone disposed at substantially the selected depth and comprising the monocrystalline semiconductor material damaged by lattice defects, i.e., end-of-range implant damage. Undamaged material below the selected depth comprises a first layer of the monocrystalline semiconductor material. The wafer is heated under conditions effective to convert the amorphous layer to a second layer of the monocrystalline semiconductor material and to coalesce the zone of damaged monocrystalline semiconductor material, thereby forming a substantially planar intrinsic gettering zone of substantially pure semiconductor material that includes active gettering sites disposed at substantially the selected depth. An insulating bond layer on one surface of a handle wafer is bonded to the surface of the wafer to form a bonded semiconductor-on-insulator substrate comprising a handle wafer, an insulating bond layer, and a device wafer of monocrystalline semiconductor material. The device wafer includes a substantially planar intrinsic gettering zone comprising substantially pure semiconductor material and including active gettering sites. The described bonded substrate is employed in the fabrication of semiconductor devices and integrated circuits.

摘要： A power trench MOS-gated transistor is constructed with a buried gate to source dielectric inside a gate trench region. In the innovative device, a thick oxide (grown or deposited) is used to define the height of the trench walls. A body region is initially formed by selective epitaxial growth and etch back. Source regions are formed also by selective epitaxial growth. The body is finally formed by selective epitaxial growth and etch back. The oxide is removed from the trench, the trench walls are oxidized to form a gate oxide, and doped polysilicon fills the trench to form a gate. By the formation of the source region using the spacer etch, this process simplifies the fabrication of power trench gated devices, and provides for increased contact surface area without increasing device size.
