Semiconductor Technology II: Besides a sufficient inventory of process technologies, the generation of an integrated circuit requires a solig knowledge of the interaction between the device properties and the individual process steps. Effort has to be minimized while performance must be increased. This art named process integration is the major topic of the second part of the course.
Starting with the basic function of a MOS field effect transistor, we will develop simple structures of integrated circuits and always focus on the interaction of device performance and manufacturing technology. Concepts of self alignment as well as parasitic effects will be explained. Finally we will run through the whole process sequence for the fabrication of a CMOS product.

The size of electronic building blocks is continuously decreasing reaching dimensions of a few nanometers. Ultimate scaling of electronic devices can be achieved by using single molecules as active building blocks for electronics. Electronic circuits, which are based on such building blocks, open completely new possibilities for applications. This lecture first will set the theoretical basis necessary for the understanding of the phenomena in charge transport in nanostructures. Furthermore, experiments characterizing single molecule junctions, created by electromigration, break junctions or microscopy, will be discussed. A special focus will be on possible applications in the use of such structures as building blocks for future electronic circuits. Basic knowledge in solid state physics or chemistry will help but is not strictly required.

IMPORTANT:
- Project work must be registered using the form: Project Work Registration (OME)
- Supervisors should use this form to grade your project: OME Project Work Result Sheet
- Both forms can be found here (path: physics - examinations).
The Major module aims at providing OME students with the flexibility to specialize in their favorite field. Students can choose between the following two research areas:
- Physics OR
- Electronics
Students must complete the following during their OME studies (normally during semesters 2 and 3):
- two courses of their chosen area with an exam each and
- one ungraded lab (rotation) course
The organization of lab course varies according to your chosen specialization area, i.e., it may or may not be integrated in your chosen courses. Please discuss with your lecturers. Upon completion, you must submit your result sheet (Physics - Examinations - Lab Course Sheet) to the examination office.
