With the increasing of seal face's positive taper, the stiffness of gas film is obviously increased, but the leakage of seal is also increased.

密封端面正锥度的增加能使密封气膜刚度显著提高，但同时也使密封的泄漏量有所增加。

In LCDs silane gas breaks down into a film of silicon that forms the transistors that stimulate the pixels in the screen. (Flat-panel screens are essentially large semiconductor devices that sit on pieces of glass rather than on silicon wafers.) Another gas, nitrogen trifluoride, cleans the chambers in which both chips and LCDs are made.

FORBES: Suddenly Sexy

But Dr Bruel found that if a hydrogen-treated wafer is first fused to another wafer that has been given a glass coating, the force of the gas bubbles will instead cause a thin silicon film to peel off the one and on to the other.

ECONOMIST: Chip technology

It has set up a rapid response team to counter publicity for the film by using two Washington-based groups that lobby for gas and oil companies: the Independent Petroleum Association of America and Energy in Depth.
