Serial stacking of high voltage devices in a SOI process to achieve higher operating voltages is an alternative approach to layout and material modifications being necessary in a conventional quasi-vertical approach. Based on a sufficient 900 V trench isolation the stacking was first tested with existing lower voltage diodes and compared to new 900 V diodes with the conventional quasi-vertical construction.

To meet stringent quality requirements like 0 ppm, it's essential to build in robust quality and verify it during product design development. This webinar will review the impact of manufacturing variations and tolerances in semiconductor processes for zero-failure-quality targets. It will introduce countermeasures like six-sigma design practice, design centering, robustness indicator figures (RIF) and statistical reliability modeling. Quality verification and robustness validation concepts will be discussed, as well as selected quality assurance methods that can be applied in the manufacturing chain.

First-time-right in analog design depends not only on proper consideration of process variations and design sensitivities but also on device reliability. Device aging can jeopardize performance and long-term product success and therefore should be taken into account as early as possible in the development. This webinar provides an overview of reliability physics and considerations and gives guidance on reliability conscious circuit design. Critical issues are discussed and future options for a reliability-aware design flow are indicated.

For industrial and automotive applications a 0.35μm aluminium CMOS process is one of the common used technologies. An increasing demand on extended operating conditions must be fulfilled especially for high current carrying metal lines. A new design concept is to modify the shape of these lines. The use of slots especially of octahedron slots demonstrates a better robustness towards electromigration in upper metallization layers. Another benefit is the good reliability under pulsed DC conditions primarily in comparison to wide homogeneous filled metal lines.

The fabrication of semiconductor devices, even in the area of customer oriented business, is one of the most complex production tasks in the world. A typical wafer production process consists of several hundred steps with numerous resources including equipment and operating staff. A reasonable assignment of each resource at each time for a certain number of wafers is vital for an efficient production process. Several requirements defined by the customers and facility management must be taken into consideration with the objective to find the best trade-off between the different needs.

The fabrication of semiconductor devices, even in the area of customer oriented business, is one of the most complex production tasks in the world. A typical wafer production process consists of several hundred steps with numerous resources including equipment and operating staff. Smaller foundries with a high product mix and a low technology volume need reasonable assignments of each limited resource at each time. Several requirements defined by the process requirements, customers and management must be taken into consideration with the objective to find the best trade-off between the different needs.
