8.4.1. Wafer Bonding

Try these first

1. 1.

   What is wafer bonding?

   Hint

   Think about why this would be important in fabrication.

2. 2.

   Name one type of wafer bonding technique.

   Hint

   Consider the unique materials involved.

3. 3.

   What process uses an electric field to bond silicon to glass?

   • Anodic Bonding
   • Fusion Bonding
   • Adhesive Bonding

   Hint

   This method is key for creating strong connections with glass.

4. 4.

   True or False: Fusion bonding requires the use of adhesives.

   • True
   • False

   Hint

   Think about how strong the bond should be.

5. 5.

   Evaluate the impact of using adhesive bonding in a MEMS device designed for medical diagnostics. Consider aspects like durability and material interaction.

   Hint

   Think about both the physical properties and chemical interactions.

6. 6.

   Design a MEMS device that requires both anodic and fusion bonding. Explain how you would incorporate each bonding process effectively.

   Hint

   Think about where each bonding technique can provide the best benefits.
