Abstract: A semiconductor device has a deep trench in a semiconductor substrate of the semiconductor device, with linear trench segments extending to a trench intersection. Adjacent linear trench segments are connected by connector trench segments that surround a substrate pillar in the trench intersection. Each connector trench segment has a width at least as great as widths of the linear trench segments connected by the connector trench segment. The deep trench includes a trench filler material. The deep trench may have three linear trench segments extending to the trench intersection, connected by three connector trench segments, or may have four linear trench segments extending to the trench intersection, connected by four connector trench segments.

Abstract: A semiconductor device has a first trench and a second trench of a trench structure located in a substrate. The second trench is separated from the first trench by a trench space that is less than a first trench width of the first trench and less than a second trench width of the second trench. The trench structure includes a doped sheath having a first conductivity type, contacting and laterally surrounding the first trench and the second trench. The doped sheath extends from the top surface to an isolation layer and from the first trench to the second trench across the trench space. The semiconductor device includes a first region and a second region, both located in the semiconductor layer, having a second, opposite, conductivity type. The first region and the second region are separated by the first trench, the second trench, and the doped sheath.

A first dielectric layer is provided on a side of the first capacitor opposite the substrate. Further, a second capacitor is present on a side of the first dielectric layer opposite the first capacitor. The second capacitor has a second width that is smaller than the first width. The IC also has a second dielectric layer and a first metal layer. The second dielectric layer is on a side of the second capacitor opposite the first dielectric layer. The first metal layer is on a side of the second dielectric layer opposite the second capacitor.

Abstract: The present invention provides a method for monitoring a shift in a buried layer in a semiconductor device. The method for monitoring the shift in the buried layer, among other steps, includes forming a buried layer test structure in, on or over a substrate of a semiconductor device, the buried layer test structure including a first test buried layer located in or on the substrate, the first test buried layer shifted a predetermined distance with respect to a first test feature. The buried layer test structure further includes a second test buried layer lodated in the substrate, the second test buried layer shifted a predetermined but different distance with respect to a second test feature. The method for monitoring the shift in the buried layer may further include applying a test signal to the buried layer test structure to determine an actual shift relative to the predetermined shift.
