Optical Proximity Correction (OPC) is an important technique we use to fix mistakes that happen during the imaging process in lithography. It involves making changes to the mask…
Verilog is a language we use to describe how digital systems work, like network switches, microprocessors, memory, or flip-flops. You can use it to check if analog and…
Electromigration (EM) is a phenomenon where metal ions in an interconnect get displaced due to the flow of electrons. You need to consider how this affects our circuit…
Parasitic Channel A parasitic channel in a MOSFET happens when unintended conductive paths form between the source and drain regions due to poor design or environmental factors. You…
VLSI layout design, both Multiplier and Finger concepts are used to optimize transistor layout for better performance, area, and routing. Here’s the difference between the two: What is…
The Body (Back Gate) Effect is a phenomenon in MOS transistors where the threshold voltage (VT) of the transistor changes due to a voltage applied to the transistor’s…
Zero-Temperature-Coefficient (ZTC) is the point at which the performance of a transistor becomes independent of temperature changes. Normally, when the temperature increases, we see two main effects: the…
The Narrow-Channel Effect refers to a phenomenon where the threshold voltage (VT) of a MOSFET increases as the width of the channel becomes smaller. This happens because, as…
When it comes to N-PLUS (NMOS Source-Drain) or NSD and P-PLUS (PMOS Source-Drain) or PSD masks, you might wonder why these are necessary in the process of fabricating…
In semiconductor manufacturing, you might have come across the term “STI” or Shallow Trench Isolation. I want to share some thoughts on what STI is and why we…
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…
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…
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…
Metallic interconnections are widely used in electrical systems because they effectively carry electric current and support information transfer. Here’s why: Metallic interconnections I find it fascinating that metallic…
I always use the grep command for this. You can simply run: This will count the occurrences of ‘word’ in the file. The -o option in grep makes…
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…
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…
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…
As I delve into the world of semiconductor manufacturing, I’m constantly amazed at the relentless pursuit of miniaturization. Today, the semiconductor industry is aggressively moving toward printing ever-decreasing…
List of VLSI Project for EC, ECE & ME students VLSI Projects idea: The process of building thousands of transistors onto a single chip to create an integrated…
To find all files containing a specific string of text on a Linux system, you can use the command combined with options to perform a recursive search and…
What is Electromigration Effect in VLSI? Material migration encompasses several forced transport processes in solid materials, such as chemical diffusion due to concentration gradients, migration caused by temperature…
