This paper presents a new way of dealing with drinkable water shortness all over the world. The developed devices’ functionality is based on the well-known and established SODIS (SOlar DISinfection) method. The whole device, Scipio—Scientific Purification Indicator, is designed in a way, that it is self-powered by solar cells and can be placed inside a bottle in order to provide best measurements. The device is capable of communicate via Bluetooth with other devices. Thus, an observation or control of the correct application of the SODIS method can be established. The paradigm shift we offer in terms of development aid not to simply help the people but to empower them to care for themselves. It is a very important that everyone can purify their own drinking water without the need of subsequent supplies.

Scaled down CMOS transistors are prone to degra dation and process variation. This necessitates a transistor model that provides an insight into the internal dependencies between these two crucial effects. Models for modern transistors and their degradation behavior are hardly attachable. This paper proposes a modified BSIM6 model which includes degradation due to BTl and HCI and in addition process variations. The application of this method is demonstrated on the basis of a single MOSFET and an inverter stage. The results can be used in the grn/1d work flow or for yield estimation on circuit level.
