In this module, you will dive into essential deposition techniques for biosensor fabrication. You will explore Physical Vapour Deposition (PVD) methods, including E-beam evaporation, thermal evaporation, and sputtering, to understand how to precisely layer thin films for optimal sensor functionality. Lab sessions will enhance your practical knowledge of the equipment and processes for creating uniform, high-quality coatings. Additionally, you will learn how Chemical Vapour Deposition (CVD) uses chemical reactions to create robust and adaptable sensor surfaces. These techniques are crucial for developing biosensors with superior sensitivity, durability, and functionality.

In this module, you will start with an introduction to lithography and learn patterning methods for creating precise microscale features vital for advanced sensor designs. You'll engage in numerical problem-solving to reinforce your understanding of lithography and micromachining, followed by a practical demonstration of the lithography process. Then, you'll explore micromachining's role in structuring sensor components, focusing on both wet and dry etching techniques, with a demonstration of wet etching to show how material layers are selectively removed, giving you a comprehensive grasp of micromachining applications in biosensor development.

In this module, you will explore advanced fabrication techniques for gas sensors, learning about bulk and surface micromachining, as well as sacrificial layer methods. Understand how these approaches apply to gas sensor fabrication and how material and structural choices affect sensor performance and durability. Additionally, you will delve into the principles and applications of other sensors, including humidity, proximity, and radiation sensors. By examining these diverse sensor types and their fabrication processes, you will gain insights into tailoring sensors for specific biomedical applications.

In this module, you'll gain a solid understanding of commercial sensor fabrication processes and key technologies for modern sensor integration. You'll start by exploring 3D printing, including its types and applications in additive manufacturing to create custom sensor housing and components. Next, you'll dive into Printed Circuit Board (PCB) design, learning schematic and layout design for effective sensor interfacing. You'll also develop practical skills in biosensor interfacing and participate in a wire bonding demonstration, equipping you with the technical foundation to connect and integrate biosensors into functional electronic systems.
