Microelectronics, Electronics 1, Digital technic 1-2

A kötelező előtanulmányi rend az adott szak honlapján és képzési programjában található.

Students can choose from two practical tasks at the beginning of the semester.

1.      Design of a digital integrated circuit

2.      Semiconductor technology process

In the digital circuit design task, a moderately complex ASIC has to be designed from specification to full layout using a Verilog behavioural description. The circuit can be implemented on an FPGA for verification.

In case of the semiconductor process, the production steps of a simple monolite integrated circuit should be followed from qualifying the semiconductor material to packaging, including doping, oxide growth, photolithography and calibration.

Digital design branch

1.      Getting familiar with the hardware environment and operating system.

2.      Getting familiar with open IC design systems. Getting to know a standard IC design system (Mentor/Cadence) through an example.

3.      Design of digital circuits with top-down methodology.

4.      Getting familiar with synthesis tools.

5.      Input of the behaviour of the system using hardware description language.

6.      Validation of operation with logic simulation.

7.      Synthesis, technology-dependent optimization, runtime analysis.

8.      Automatic ASIC layout generation.

9.      Implementation in FPGA, verification.

Semiconductor technology branch

1.      Creation of integrated circuits.

2.      SI wafer preparation.

3.      Thermal oxidation.

4.      Photolithography.

5.      Doping with diffusion.

6.      Metal layer deposition.

7.      Thermal treatment.

8.      Packaging.

9.      Calibration, characterization.

10.  Industrial lookout.

Computer or technology laboratory practice. Design practice is done in computer laboratory in pairs. Technology laboratory takes place in the clean room of the department where groups of 4-6 people go through the technology steps on one wafer. Validation, qualification and calibration of the complete circuit is also the task of the groups. Timetable is arranged in the beginning of the semester.

The course ends with a mid-term mark. The mid-term mark is based on the work during the semester and the assignments handed in. In the technology laboratory, the condition of the mid-term mark is to finish all process steps and hand in a report.

There is one repeat possibility in the supplementary period.

By appointment with the instructors.

Literature accessible on the web page of the department, hand-outs during the laboratories.
