Q & A

What is the primary purpose of a mask in Intel's manufacturing process?

A mask is a template used to print circuitry onto a silicon wafer, which is essential for creating semiconductor chips.

How does the creation of a mask begin?

The creation of a mask begins with computerized drawings from Intel chip designers, which are the blueprints for the chips and their billions of transistors.

What is the significance of the electron beam in mask production?

The electron beam scans the surface of the mask and prints the circuitry pattern onto it, ensuring the mask is perfect with zero defects.

How long does it take to process a completed mask?

It takes about five days to process a completed mask by a mask operation.

What is the role of stepper and scan machines in using the mask?

Stepper and scan machines shine light through the mask, then through a lens to reduce the image, and then onto the surface of the wafer to create hundreds of individual die.

How many masks are required to print the many layers of an Intel 14-nanometer die?

Printing the many layers of an Intel 14-nanometer die requires more than 50 masks.

What is the significance of the famous 1978 photo featuring Andy Grove, Robert Noyce, and Gordon Moore?

The photo features a mask made of mylar, which was a design for the 8080 CPU, showing the evolution of mask technology from hand-drawn circuit lines to nanometer-scale blueprints.

How has the size of the mask changed from the 1978 photo to today?

Today's masks are six by six inch pieces of quartz a quarter inch thick, compared to the mylar mask in the 1978 photo which was about the size of two monopoly boards.

What is the data capacity of a single 14-nanometer mask?

A single 14-nanometer mask contains the equivalent of about five petabytes of data.

How does Intel's in-house mask operation provide a competitive advantage?

Intel's in-house mask operation allows it to be one of the few semiconductor manufacturers with its own mask production, ensuring high-quality masks for its factories.

How many masks does Intel's mask operation produce annually?

Intel's mask operation (IMO) produces thousands of masks annually.
