Scanning electron microscope

[Sweet]

Hi everybody

I worked on various electronic system and produce prototype of them in the electronic field and by rely on empirical work.

Recently I entered in Nano-electronic area which relates to development of electronic devices and components in a very small scale.

My field of study is Nano-electronic and electronic but I like to work as an expert on development of SEM and I would like to gain experience and knowledge in this field. Indeed I am really determined to do this job with great enthusiasm and decided to choose my PHD course in manufacturing and design of this system.

Right now I focused on studying the structure of electron microscope in order to reach a right insight and then I want to study SEM and its kinds to get familiar with all aspects of project for setting clear and precise goal to manufacture a prototype.

I keep studying and researching regarding the path, in spite of all contempt I have faced so far.while tolerating all these is too painful, I am still delighted because it demonstrates the magnitude of the task I have been through.

A very important point is that I don’t want to copy the similar system; moreover, I look for a great perception of designing and developing this system in a scientific way.

would be so grateful if I know your point of view or recommend some books or articles which help me to have a better understanding.

The best way to do that is to work for a SEM manufacture. The general term is called e-beam. SEM is a portion of it, the other part is e-beam lithography. They are fundamentally the same. E-beam lithography has more advanced optical system.

Three decades ago, this would be easier, as government was funding this type of research. Nowadays, there is no funding and professor won't teach you how to do that any more.

Designing an electron microscope is not cheap. Just the simulation software package will run you $250k. It also costs you $10k+ for annual service. It will likely cost more than $5 millions to get a new design.

There are a few projects here where people are building or modifying SEMs (or trying to).

A DIY "STM" could be easier to make at home.. No vacuum needed. And the VoltNuts here know well how to measure the small currents..

STM is the easiest to DIY (low hundreds of dollars to a couple thousand at most, and a few hours' work), followed by AFM as a close second. Then SEM is third easiest (but much more difficult than STM & AFM), followed by TEM.
