My Crystal Growth and MOCVD Experiences over the YearsPhil 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.

MR Research  MR 100 MOCVD ReactorMR100 being rebuilt (resurrected) after severe fire damage, we named it the “Phoenix” Eindhoven - Holland
India’s first 4Kg Single GaAs Crystal by LEC MethodDirector of OperationsChief  EngineerDelhi, India
7.5T  Superconducting Magnet being chargedLN2 being delivered to the outer tankLiquid Helium Cryopumped to inner tank.A 7.5Tesla cryocooled large bore superconducting magnet system beingcharged with Liquid Nitrogenand Liquid Helium. The superconducting magnet has been designed and custom built tobe mounted onto the frame of CI 358 crystal growth station. Victoria, British Columbia, Canada
7.5 Tesla Superconducting Magnet Installed on CI358To 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
Cambridge Instruments Autox CZ Crystal Growth StationExample of crystals grownYttrium Aluminum Garnet (YAG, Y3Al5O12)Designation for System is Torino ItalyGadolinium Gallium Garnet (GGG, Gd3Ga5O12) Crystal Growth System CI351 (III-V  1Kg.) This system was commissioned after successfully completing three consecutive single GaAs crystals growth runs.Liquid encapsulated Czochralski (LEC). Voreppe -France

Crystal Growth System CI351 (III-V  1Kg.) 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
India and its PeopleHaving 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 resourcefulIn 1947 India gained Independence From Britain.Since its independence from the British rule in 1947, India has been making considerable progress in the Sciences.
