发明名称 Methods of forming recessed access devices associated with semiconductor constructions
摘要 The invention includes methods of forming recessed access devices. A substrate is provided to have recessed access device trenches therein. A pair of the recessed access device trenches are adjacent one another. Electrically conductive material is formed within the recessed access device trenches, and source/drain regions are formed proximate the electrically conductive material. The electrically conductive material and source/drain regions together are incorporated into a pair of adjacent recessed access devices. After the recessed access device trenches are formed within the substrate, an isolation region trench is formed between the adjacent recessed access devices and filled with electrically insulative material to form a trenched isolation region.
