    摘要: Processes for forming isolation structures for semiconductor devices include forming a submerged floor isolation region and a filed trench which together enclose an isolated pocket of the substrate. One process aligns the trench to the floor isolation region. In another process a second, narrower trench is formed in the isolated pocket and filled with a dielectric material while the dielectric material is deposited so as to line the walls and floor of the first trench. The substrate does not contain an epitaxial layer, thereby overcoming the many problems associated with fabricating the same.

    摘要: Methods are disclosed for forming a varied impurity profile for a collector using scattered ions while simultaneously forming a subcollector. In one embodiment, the invention includes: providing a substrate; forming a mask layer on the substrate including a first opening having a first dimension; and substantially simultaneously forming through the first opening a first impurity region at a first depth in the substrate (subcollector) and a second impurity region at a second depth different than the first depth in the substrate. The breakdown voltage of a device can be controlled by the size of the first dimension, i.e., the distance of first opening to an active region of the device. Numerous different sized openings can be used to provide devices with different breakdown voltages using a single mask and single implant. A semiconductor device is also disclosed.
