What Are the Challenges of Using Copper Interconnects?
When we talk about using copper in chip manufacturing, we must consider some specific challenges. As you might know, copper has become the go-to material for interconnects in…
Analog DesignA collection of 35 posts
The process of building thousands of transistors into a single chip to create an integrated circuit (IC) is known as very-large-scale integration, or VLSI. When complex semiconductor and communication technologies were being developed in the 1970s, VLSI got started.
How does a voltage pulse affect an interconnect?
When a voltage pulse is applied to an interconnect, it creates an electric field in the interconnect. Let me explain how this works. I’ve found that in a…
What is Fermi level?
Fermi level Let me explain the concept of the Fermi level in a way that feels more conversational and human. When we talk about the Fermi level in…
Why is the Cut Mask Essential in the Self-Aligned Double Patterning (SADP) Process?
Cut Mask In the SADP process, we use a cut mask, also known as a block mask, to trim the tips of lines created in the first litho-etch…
Why do we use Dijkstra’s algorithm for buffered routing in VLSI?
We use Dijkstra’s algorithm for buffered routing because it tends to be very fast and efficient, especially for early planning and estimation. I think you’ll appreciate the speed…
Why do we fill via holes with tungsten in VLSI Technology
We fill via holes with tungsten in VLSI technology because tungsten has low stress and high resistance to electromigration, which makes it a reliable material for ensuring good…
