4.6.1. Design Rules

Try these first

1. 1.

   What are design rules?

   Hint

   Think about what criteria help in making sure something can be produced.

2. 2.

   Why is yield optimization important?

   Hint

   It relates to efficiency in production.

3. 3.

   What is the primary goal of yield optimization in MEMS?

   • To reduce costs
   • To maximize successful production
   • To limit design flexibility

   Hint

   Think of it as maximizing what comes out of a production line.

4. 4.

   True or False: All mems devices can be manufactured at any foundry regardless of design.

   • True
   • False

   Hint

   Consider the limitations of manufacturing facilities.

5. 5.

   You are tasked with designing a MEMS sensor for medical applications, emphasizing low noise and high reliability. What design considerations will you incorporate to address manufacturability and testing?

   Hint

   Research materials that have proven performance in similar applications.

6. 6.

   Consider you have a MEMS device that is yielding poorly on initial runs. What steps would you take to revise the design based on yield optimization strategies?

   Hint

   Look for points in the design that may be too tight in tolerance.
