and the (stationary) substrate is too great, an excessively great coating thickness is to be observed at the center of the substrate, decreasing greatly toward the margins. If the distance between the target and the (stationary) substrate is too small, it can be observed that the coating thickness in the area of the erosion pit is especially great, while it decreases greatly on either side of the erosion pit. As a result, such sputtering cathodes can be used only for coating substrates which have a much smaller diameter than the target.
Varian's "Con Mag" sputtering cathode, described above, springs from the attempt to improve the uniformity of the coating thickness by making not only the magnet systems but also the corresponding target parts completely separate electrically. This, however, requiresTrade unionists must stand with Brazilian workers against the ‘right wing coup’

I recently visited Rio De Janerio as a member of the Unite–United Steelworkers (Workers Uniting) delegation to the IndustriALL Global Congress. IndustriALL is the global federation covering manufacturing and energy trade unions worldwide.

The Congress was fortunate to be addressed by former Brazilian president Lula da Silva, who made a powerful and emotional speech setting out his government’s significant achievements and the crisis now facing working people following the coup against democratically elected President Dilma Rousseff.

Despite the coup, Lula is still eligible to stand for office — hence the crackdown he faces from the right-wing government. Lula is still the most popular politician in Brazil, but could face arrest and detention by his opponents at any time, in
