    摘要: A semiconductor process and apparatus provide a planarized hybrid substrate (15) by thermally oxidizing SOI sidewalls (90) in a trench opening (93) to form SOI sidewall oxide spacers (94) which are trimmed while etching through a buried oxide layer (80) to expose the underlying bulk substrate (70) for subsequent epitaxial growth of an epitaxial semiconductor layer (96). In this way, SOI sidewall oxide spacers (94) are formed that prevent epitaxial SOI sidewalls from being formed in the trench opening (93) during the epitaxial growth step, and that can be readily removed during any subsequent STI etch process

    摘要: A semiconductor process and apparatus provides a planarized hybrid substrate (16) by removing a nitride mask layer (96) and using an oxide polish stop layer (92) when an epitaxial semiconductor layer (99) is being polished for DSO and BOS integrations. To this end, an initial SOI wafer semiconductor stack (11) is formed which includes one or more oxide polish stop layers (91, 92) formed between the SOI semiconductor layer (90) and a nitride mask layer (93). The oxide polish stop layer (92) may be formed by depositing a densified LPCVD layer of TEOS to a thickness of approximately 100-250 Angstroms.
