Abstract:
1. A circuit structure, comprising: a silicon substrate having at least two etching trenches formed therein and defining a silicon block having sidewalls, said etching trenches etched out in a manner adjoining said sidewalls of said silicon block, said etching trenches disposed at angles with respect to one another prescribed by a form of said silicon block, said etching trenches including a first etching trench and a second etching trench disposed adjacent said first etching trench; first and second doped diffusion regions extending from said first and second etching trenches into said silicon block and having an overlap region; and layer structures disposed in said etching trenches, said layer structures including conductive structures disposed in said etching trenches, said conductive structures within said first etching trench and said conductive structures within said second etching trench being electrically connected to one another by said first and second diffusion regions extending from said first and second etching trenches into said silicon block.
