ABSTRACT:
The invention includes a method of forming semiconductor circuitry. A monocrystalline silicon substrate is provided, and a mask is formed which covers a first portion of the substrate and leaves a second portion uncovered. A trench is formed in the uncovered portion and at least partially filled with a semiconductive material that comprises at least one atomic percent of an element other than silicon. The mask is removed and a first semiconductor circuit component is formed over the first portion of the substrate. Also, a second semiconductor circuit component is formed over the semiconductive material that at least partially fills the trench. The invention also includes semiconductor constructions.
