Learn the fundamentals of microfabrication and nanofabrication by using the most effective techniques in a cleanroom environment. Microfabrication and nanofabrication are the basis of manufacturing for nearly all modern miniaturized systems that are ubiquitously used in our daily life. Examples include; computer chips and integrated sensors for monitoring our environment, cars, mobile phones, medical devices and more.
Micro- and nanofabrication can be taught to students and professionals by textbooks and ex-cathedra lectures, but the real learning comes from seeing the manufacturing steps as they happen.
In this engineering course, we will go a step beyond classroom teaching to not only explain the basics of each fabrication step but also show you how it’s done through video sequences and zooming into the equipment.
What you'll learn
- How to select the correct fabrication process for a specific micro-device or microsystem
- Establish the workflow for the cleanroom processes
- Identify how physical and chemical phenomena govern miniaturized systems for various applications
- Resource planning for a given microsystem fabrication
Week 1: MEMS and cleanroom introduction
This module introduces the basics of electromechanical systems (MEMS) and cleanroom fabrication.
Week 2: Chemical vapor deposition (CVD)
This module on chemical vapor deposition or CVD describes in detail basic principles of CVD and will show you the cleanroom infrastructure that is used to run a CVD process.
Week 3: Physical vapor deposition (PVD)
This module on physical vapor deposition describes in details the two main PVD methods; thermal evaporation and sputtering.
Week 4: Lithography
This module on lithography describes in details the two main resist patterning methods: optical and electron beam lithography.
Week 5: Dry etching
This module on dry etching describes etching in a gas environment. We will introduce etching directionality and anisotropy and give a few simple rules for choosing dry etching processes for specific materials in a plasma reactor and provide theoretical concepts that characterize a plasma in a dry etching equipment.
Week 6: Wet etching
This module on wet etching describes etching in a liquid environment. We will introduce anisotropic wet etching of silicon substrates, where certain lattice planes are etched and others not, isotropic etching of silicon, and finally thin membrane microfabrication techniques using wet etching.
Week 7: Inspection and metrology
This module describes methods of inspection and metrology based on four technique categories: optical, mechanical, charged beam and electrical.
De nombreux secteurs industriels (transports, bâtiment, loisirs, ...) s'intéressent aux matériaux composites dans un souci d'allègement des structures. Une utilisation efficace de ces matériaux requière la maîtrise de l'ensemble du processus de conception, du concept initial au produit final. La modélisation de la réponse mécanique d'une pièce composite est une étape essentielle pour assurer son adéquation au cahier de charges. Ce cours vous permettra d'acquérir les principaux outils nécessaires à la description du comportement des composites stratifiés aux différentes échelles d'observation, de celle de la fibre à celle de la pièce. Ce MOOC est un module indépendant de l'ensemble 'Pratiques en Conception des Structures Composites' : fabrication et caractérisation, modélisation.
Learn the technologies used to manufacture products we use every day, and the fundamental principles required to take processes to scale. Have you wondered how something was manufactured? Do you want to learn what it takes to turn your design into a finished product? This course introduces a wide range of manufacturing processes including machining, injection molding, and 3D printing; and explains the fundamental principles and practices of manufacturing at scale.
This course will help you understand how 3D printing is being applied across a number of domains, including design, manufacturing, and retailing. It will also demonstrate the special capabilities of 3D printing such as customization, self-assembly, and the ability to print complex objects. In addition to business applications, this course will also examine how individuals, including those in developing countries, are using this technology to create solutions to the problems they face.
This Model-Based Systems Engineering (MBSE) course and the Digital Thread courses featured earlier in this specialization bring together the concepts from across digital manufacturing and design, forming a vision in which the geometry of a product is just one way of describing it. MBSE is where the model resulting from the evolution of system requirements, design, analysis, verification and validation activities is the focus of design and manufacturing.
Extreme variability is a fact of life in manufacturing environments, impacting product quality and yield. Through this course, students will learn why performing advanced analysis of manufacturing processes is integral for diagnosing and correcting operational flaws in order to improve yields and reduce costs.
The nature of digital manufacturing and design (DM&D), and its heavy reliance on creating a digital thread of product and process data and information, makes it a prime target for hackers and counterfeiters. This course will introduce students to why creating a strong and secure infrastructure should be of paramount concern for anyone operating in the DM&D domain, and measures that can be employed to protect operational technologies, systems and resources.
Lean is a powerful methodology that enables managers and employees to shift their mindset and helps companies to keep their business sustainable by creating competitive advantage. Today, in an increasingly complex and dynamic world, where companies struggle to maintain competitive advantage, Lean is more important than ever.
Enterprises that seek to become proficient in advanced manufacturing must incorporate manufacturing management tools and integrate data throughout the supply chain to be successful. This course will make students aware of what a digitally connected enterprise is, as they learn about the operational complexity of enterprises, business process optimization and the concept of an integrated product-process-value chain.
Discover manufacturing and agriculture’s role in the history of China as we explore Chinese culture through artifacts and relics. Chinese archaeology is one of the fastest growing and most exciting fields of study in China. With a wealth of cultural relics unearthed this past century, the world’s fascination with China’s rich history has been renewed.
MOOCs – Massive Open Online Courses – enable students around the world to take university courses online. This guide, by the instructors of edX’s most successful MOOC in 2013-2014, Principles of Written English (based on both enrollments and rate of completion), advises current and future students how to get the most out of their online study, covering areas such as what types of courses are offered and who offers them, what resources students need, how to register, how to work effectively with other students, how to interact with professors and staff, and how to handle assignments. This second edition offers a new chapter on how to stay motivated. This book is suitable for both native and non-native speakers of English, and is applicable to MOOC classes on any subject (and indeed, for just about any type of online study).
