LSI design flow and EDA

What is it called to hand over the data for mask making to manufacturing after design and verification are complete?

  1. ADicing
  2. BTape-out
  3. CBonding
Show answer and explanation

Answer: B. Tape-out

Tape-out is the handover of the final design data (mask data) to manufacturing, a major milestone in the design process. The name comes from the time when data was delivered on magnetic tape. If a bug is found after tape-out, masks must be remade, at great cost in money and time.
