5.5. Wafer Bonding

Try these first

1. 1.

   What does wafer bonding aim to achieve?

   Hint

   Think about why materials might need to be joined.

2. 2.

   Name one type of wafer bonding.

   Hint

   We discussed three specific methods.

3. 3.

   What is one purpose of wafer bonding in MEMS?

   • To increase wafer size
   • To create multi-layered devices
   • To reduce production time

   Hint

   Think about the primary goal of the process, not secondary effects.

4. 4.

   Is fusion bonding one of the bonding methods?

   • True
   • False

   Hint

   Recall our list of bonding methods.

5. 5.

   Consider a scenario where a MEMS device fails due to improper adhesive bonding. Analyze potential causes and suggest preventative measures.

   Hint

   Reflect on how each step in adhesive application can impact overall bond integrity.

6. 6.

   Discuss how advancements in fusion bonding could transform MEMS applications in medical devices.

   Hint

   Think about the implications of material properties and functionality in medical scenarios.
