Ruminations on the electronics industry from David Manners, Senior Components Editor on Electronics Weekly.
Planar Devices Next Year.
Epitaxial transistors very soon. Planar devices by early 1962. These are the basic plans of the Ferranti Electronics Department, but they are by no means the only plans.
So, over 50 years ago, starts a story in Electronics Weekly’s edition of April 19th 1961.
The story continues:
Visiting the Gem Mill and Wythenshawe works of Ferranti recently, I was told work is proceeding at high speed on epitaxial techniques, and the wafers of material are being produced by Ferranti in their own plant.
Epitaxial layers are being deposited at the rate of one micron per minute, and it was stated that a sufficiently high rate of production to meet demands could be maintained.
Work on epitaxy began at Ferranti’s early in 1960l.
Work on planar devices is not so advanced but progress is being made.Tags: april 19th, electronics department, high speed, micron, transistors
