A Messy Collections of my Semiconductor Learnings

Getting Started

There is a lot of information that is needed to get started. Here I have listed some videos that helped me when I got started.

If you are interested to learn more, please have a look at these links which includes some factory tours and different explanations on the semiconductor manufacturing process.

Industry Standards

Majority of the semiconductor industry is governed by SEMI standards (Shop semi.org). 

Some of the commonly referred SEMI standards for equipment manufacturing would be as follows.

• E Series: Equipment Communications

Substrates and their sizes

Primarily the substrate processed will be the wafer. However, the wafer can be receieved as a bare wafer on fitted on to a frame with a film or tape (called tape frame or film frame) for purposes of handling during dicing.

When it comes to silicon wafers, there are 3 major sizes of wafers currently being used in industry as of 2023.

• 150mm (5.9 inch - reffered to as 6 inch)
• 200mm (7.9 inch - reffered to as 8 inch)
• 300mm (11.8 inch - reffered to as 12 inch)

The next thing to keep in mind about silicon wafers is that they come with either a notch or a flat side for the purposes of orienting the wafer.

• Under 200mm diameter = flat
• Over 200mm diameter = notch

For wafers which have a flat side, based on different surface treatment, but this is not always used.

In terms of tape frame / film frame there are a few standard sizes based on the wafer size which can be seen below

Some Abriviations used in the industry

Having worked in a number of industries before, one of the most disorienting things at the start of your career can be all the abbriviations that get thrown around and everyone in the room uses them like they are standard words in the English vocabulary. These are some of the common abbrivations that I have come across.
