A god send. Just got into semiconductor industry and stumbled upon this. Thanks sir.

+Chris Mack Thank you for your lecture, first of all. This is "THE BEST" course I've ever seen. But your lecture materials are too small to read when printed in paper(A4). Because 6 ppt slides are in 1 pdf page. I think 1 ppt slide in 1 pdf page is better format because downloaders can change the number of slides per 1 page as they want.

Q1: A kind of material whose conductivity is variable Q2: Doping and applying voltage Q3: A process that prints/gathers individual transistors into chips Q4: deposition --> lithography --> etching --> removing the remained mask material Q5: shooting the accelarated ions into silicon Q6: To diffuse the ions and recorver the doped silica from amorphous form to single crystal

Thanks for making your lectures available to the general public. I'm a chemistry undergraduate student applying for the 2015 Hooked on Photonics summer internship program at UW and I will recommend this video series as a great resource to get immersed in the basics of silicon photonics.Very clear and concise set of lectures, great job!

Wow It`s Just Amazing...i never understood these things during my masters studies...but after listening your lectures most of the things are now clear in my mind about the silicon processing ...this is the Best Lecture Series i have ever seen on chemical processing of Semiconductor...A Big Thanks From India...

Thank you sir from the bottom of my heart. best wishes for you. You are a great teacher i love the way you taught me all the topics i have no words to explain my feelings towards you and your efforts. Sir how can i get your help if i want to know more about other topics? Waiting for your expected response. Thank you :)

The title of this lecture should be "Silicon Semiconductor: Material Processing and Device Fabrication Overview".

Hello Lithoguru, Dr Mack, I have a question. At 14.:47, when Phosphorous is doped Si becomes n-type right. The picture shows it as p-type. Kindly, clarify that.

Found Answer from the comments. Thanks.
@ChrisMack6 жыл бұрын
Phosphorous definitely creates an n-type region. Sorry for the confusion!
@pierrojules3 жыл бұрын
Indeed, P is an n-type dopant for Si. In the periodic table of elements, Si is in the fourth column. An element belonging in a column higher than the fourth will be an n-type dopant to Si, while a p-type dopant will belong in a column ranking lower than the fourth.

Sir why mostly subtractive patterning? Why not additive? Please answer the question, thank you.
@ChrisMack5 жыл бұрын
Both are used, but in general subtractive patterning is preferred because it is either easier or cheaper to get high resolution with good control.
@tangladav12769 жыл бұрын
In your patterning example, it seems that there is an alternative easier way. It seems to me that the deposition of the photoresist is just an extra processing step that is not necessary.

Um........ photolithography is literally the heart of IC manufacturing process. It's the root of your patterning and CD process. What are you talking about? I think you're confused about what it is

P ions create p-type???
@ChrisMack9 жыл бұрын
You are right! I should have said Boron ions are used to create the p-type region that I show in slide 7.
