7.2.2 Step coverage (conformality)

Not all layers require precise thickness control. Sometimes all that matters is that the film coats the entire surface, including vertical walls and (most difficult) the corners at the bottom of deep holes.

For example:

  • We may require an insulating layer of oxide between two conductors.

  • A protective titanium nitride barrier layer prevents aluminium from diffusing into silicon, and an underlying titanium adhesion layer ensures that

At 92 years old, Pete Seeger’s version of “Forever Young” by Bob Dylan. Hounded by the McCarthy anti-communists in the 1950′s, the grandfather of modern folk music.
Ironically, driving Pete Seeger underground spawned the interest of a whole generation in protest music, which helped to end the War in Vietnam and defined the 1960s rebellion.
Pete Seeger was a friend of Woody Guthrie and a major inspiration for
Bob Dylan. Pete Seeger was one of Bob Dylan&rs

3.1 ‘Making ends meet’

When you say that someone is ‘poor’, what do you mean?

Do people whom others call ‘poor’ always see themselves in that way?

One group whose identities are greatly constrained by income are the poor. But, as the questions above suggest, poverty is not a simple fact of some lives: rather, it is a concept with different meanings, and a label that we may accept or reject. This section c

2.1 How the programme progresses

The programme takes the form of a visit to Glasgow. We talked to people and asked about their image(s) of Glasgow and whether these had changed – what was the ‘old’ image; what is the ‘new’; how has it changed; what will it be like in another ten years?

The five main participants have different experiences of Glasgow and these are represented in the images which they hold and aspects of the city's character which they highlight. The themes and ideas behind the programme are al

3.7.3 Fluency

Try to make your essays flow from one sentence to the next. As we have seen, this is partly a matter of structure and partly of signposting. It is vital to think of your essay in terms of its overall structure – to move points around, and cut and trim, in search of a clear sequence for your ideas. Then, having worked out a structure, you have to ‘talk’ your reader through it, emphasising the key turning points in the essay, summarising where you have got to, showing how ea
