Semiconductor processing involves numerous critical steps, and one of the most important is photoresist stripping. This step requires careful attention because it ensures that the temporary masking layer used during patterning is fully removed without damaging the underlying structures and without leaving any residue behind. What is Photoresist Stripping? Photoresist stripping is the process ofContinue reading “Photoresist Stripping in Semiconductor Processing”

Diffusion
Let´s talk about diffusion! The diffusion is present in many semiconductor manufacturing steps. According to the semiconductor manufacturing step, the diffusion can be done with several materials and with different depths and surface concentrations. Diffusion is a two-step process: deposition and drive-in. The first one was already discussed in my previous post. Today I willContinue reading “Diffusion”
Process: the PATH to many solutions
PROCESS, PROCESS, PROCESS …. What I like most on processes is that even if they have a common concept, it can be made in so many ways that the results can be quite unique… A process is made of several steps. Let me show that if we choose a simple process like the initial cleaningContinue reading “Process: the PATH to many solutions”
Semiconductor Manpower Shortage: what is going on?
Recently I’ve been reading a lot about the semiconductor industry manpower shortage. Semiconductor is a wide knowledge subject, and many years of experience are necessary to a professional become useful for the industry. The hand labor shortage we are facing today will not be overcome so soon. This condition started a long time ago, beforeContinue reading “Semiconductor Manpower Shortage: what is going on?“
Innovation & Creativity
Another day, I was caught myself thinking about innovation … what exactly is considered innovation? So, for more obvious it seems I decided to go for search what is innovation… what I found in general lines was that “innovation can refer to something new, such as an invention, or the practice of developing and introducingContinue reading “Innovation & Creativity”
Oxidation
What is oxidation ? Oxidation is a process where an atom, molecule or ion loses one or more electrons in a chemical reaction. The first known oxidizing agent was the oxygen. Oxidation´s processes are used in many industries for several purposes. As an example, we have the heat sink anodizing process, where an oxide isContinue reading “Oxidation”
Diffusion Control
Control is the key to guarantee process quality and reproducibility. The definition of the control parameters for each manufacturing step is an important task. Knowing what you need to control will give to you the ability not only to choose the machinery to do it, but also the understanding about the importance and the influenceContinue reading “Diffusion Control”
Green-Semiconductor: the new generation
I´ve been reading a lot about the planet, and among all problems, pollution is one of great impact. The truth is that this makes me feel sad. Why we human beings, are responsible for destroying our loved home the Earth? Why don´t we use our wisdom to avoid collapsing our planet? Who said that highContinue reading “Green-Semiconductor: the new generation”
Wafer Doping – Deposition
The second, but not less important semiconductor process step, is the wafer doping. The purpose here is to explore the techniques used to growth/deposit films on the wafer surface as a drive-in diffusion pre-step, i.e., the films used as a dopants source with the objective of modify the physical, chemical, or electronic properties of theContinue reading “Wafer Doping – Deposition”
Wafer Surface Cleaning
If we observe simple details in day-to-day events, we will see how many times surface cleaning is present in several activities. Every surface coating, before coating is cleaned, and if it isn`t done correctly in some way it will appear. Cleaning surface is a production step used in several industries: automotive, electroplating, glass, polymers, andContinue reading “Wafer Surface Cleaning”
