crystal growth & mocvd experience3
TRANSCRIPT
Phil Singer
My introduction in the semiconductor industry was a unique one, I found advert in local newspaper on Wednesday morning for a Crystal Production Technician for GaAs, InP & GaP compound semiconductor crystals. (MR Research, Cambridge, UK)
That same afternoon I had interview, with no résumé or CV to speak off, and on Thursday morning got phone call asking if I could Start on the following Monday.
I have been in this industry for so many years travelling all over the world, meeting interesting people from all walks of life.
Please find a brief summary of some of my exploits in the following slides.

A 7.5Tesla cryocooled large bore superconducting magnet system being
charged with Liquid Nitrogen and Liquid Helium.
The superconducting magnet has been designed and custom built to
be mounted onto the frame of CI 358 crystal growth station.

To minimize convection mixing during the growth of semiconductor crystals an external magnetic field is applied for microgravity conditions during crystal growth of Gallium Arsenide.
Boston, Massachusetts
Gadolinium Gallium Garnet (GGG, Gd3Ga5O12)
Yttrium Aluminum Garnet (YAG, Y3Al5O12)
Designation for System is Torino Italy
Example of crystals grown
This system was commissioned after successfully completing three consecutive single GaAs crystals growth runs.
Liquid encapsulated Czochralski (LEC).
Voreppe - France

Those that commit to sit and watch crystal grow will understand how long and tedious it can be, so now and again one needs to have R&R
Yokohama – Japan
Crystal growth system CI358 (III-V 8 Kg) Celebrations in order after completing installation and commissioning of the 3 success of crystal growth of GaAs by LEC method Samsung South Korea
Suwon, South Korea
Crystal growth system CI351 (III-V 1Kg) Celebrations in order after completing installation and commissioning of the success of crystal growth of GaAs by LEC method, “A first for India”.
Madras, India
Having travelled all over the world, I find India to be the country of my best places I have visited, It was an initial culture shock. India has very proud people with extreme diversity across both religion and social status. I found that the people are very resourceful
In 1947 India gained Independence From Britain. Since its independence from the British rule in 1947, India has been making considerable progress in the Sciences.
