Abstract: Currently, semiconductor devices, VLSI circuit design and fabrication are specialized fields in electrical engineering curricula. Teaching microelectronics technology is dependent on the availability of resources and is mainly being taught at universities where a fabrication facility is available. As such, microelectronics engineering education is in transition. New thoughts are being given to topics such as what constitutes microelectronics process design fundamentals, how to shrink the gap between industrial and academic perspectives on process design and how to help students gain more experience and knowledge. This paper proposes and discusses an efficient teaching methodology for micro- and nano-electronics education. A Technology CAD (TCAD) course integrated with an online simulation laboratory at undergraduate/graduate level. The aims of the course are the development of theoretical and practical skills in semiconductor manufacturing using virtual wafer fabrication. It is expected that the students shall have increased affinity towards semiconductor fabrication, improved academic skills, abilities and knowledge. The impact of the proposed teaching methodology on the learning process will be presented.

TL;DR: G grouping of average CAD laboratory workstations in pairs is proposed in order to create remote stations capable of performing required CAD graphics processing for remote users while streaming it over the network for a near real-time experience.

Abstract: E-Learning solutions for Computer Aided Design (CAD) require high quality graphics for positive impact and high satisfaction. Software tools used for hands-on CAD laboratory exercises depend on dedicated Graphics Processing Unit (GPU) to deal with complex graphics processing needed to visualize virtual models in real-time. It is challenging to offer the same level of experience to remote users as they usually cannot afford laboratory-level hardware with dedicated GPU nor such hardware can be provided to them as part of their e-Learning experience. In this paper, grouping of average CAD laboratory workstations in pairs is proposed in order to create remote stations capable of performing required CAD graphics processing for remote users while streaming it over the network for a near real-time experience. Remote station captures video and utilizes hardware HEVC encoding, as common capability of high-end dedicated GPUs, to perform low bitrate video streaming with sub-second latency. The remote station concept enables cost-effective extension of average conventional CAD laboratory to an e-Learning remote laboratory for up to 50% additional remote users in respect to the total number of the laboratory workstations.

Abstract: Online courses have potential to reach broader audience when compared to traditional learning methods, as they can be made instantly available to groups of students dispersed over wide range of locations and time zones. Some learning topics are easily adopted to this online environment, while others may be challenging to implement as online courses due to their specific requirements and associated cost. If mastering certain topic requires hands-on experience then online course must be made interactive to match the experience of a traditional instructor-led class. Otherwise, online course will be perceived as unsatisfactory and lacking positive impact. Computer Aided Design (CAD) training requires both high performance Graphics Processing Unit (GPU) and hands-on experience with specific CAD software. Both these requirements are difficult to meet on a remote student computer without additional cost. In this paper, grouping CAD workstations into cells is proposed in order to perform required graphics processing using existing hardware and software resources available in an average CAD laboratory. Proposed cell framework uses video capture and GPU hardware encoding to stream the content to the remote students while capturing their interactive feedback for the near real-time hands-on experience. The framework requires single capture card per cell and utilizes 20% of the resources for the cell overhead processing. Remaining 80% of workstations are fully available to the online students and instructors.

Abstract: Online hardware-based educational laboratories are increasingly being deployed in traditional on-campus as well as Web-based distance-learning courses around the world. An online laboratory generally will consist of several hardware-based remote experiments. However, one particular experiment can be performed at a time by an individual student or a group of students which require a careful scheduling of the experiments. For the proper implementation of an online laboratory an efficient laboratory management system (LMS) is thus essential. Also for an online laboratory, the students need to fully understand the experimental system setup and feel comfortable as in an actual laboratory environment which, however, can be effectively done by adding suitable videos and animations etc. Besides, the students should be able to run the remote experiments, extract, save and analyze the data and submit laboratory reports online. The front end of the laboratory management system should be made browser-based so that one can use the laboratory facility from anywhere. Also, for the teachers, the laboratory management system should include an online evaluation for the quiz/viva-voce, checking experimental data, grading of submitted laboratory reports and feedback for the students. In this paper, we describe the design and prototype implementation of an online laboratory management system (for use with shared hardware-based remote laboratory resources) which may be employed for running internet-based online laboratory courses for geographically dispersed Institutions.

Abstract: We present an automated evaluation procedure to characterize MOS capacitors involving high-k gate dielectrics. Suitability of LabVIEW environment for online web-based semiconductor device characterization is demonstrated. Developed algorithms have been successfully applied to automate the MOS capacitor measurements for Capacitance-Voltage, Conductance-Voltage and Current-Voltage characteristics. Implementation of the algorithm for use as a remote internet-based characterization tool where the client and server communicate with each other via web services is also shown.
