Abstract: A low-pressure mercury vapour-filled discharge lamp
has a glass arc tube and a glass outer tube disposed
coaxially with the arc tube forming a space therebetween. A
gas is disposed in the space. The arc tube contains a gas
and is coated with a phosphor. A first seal hermetically
seals the inner tube. A second seal seals the inner tube to
the outer tube. The inner tube further contains a pair of
cathodes coupled to Dumet wires extending from the interior
of the inner tube to the outside of the lamp structure. The
pressure in the space is set at not more than 1 Pa, which is
nearly high vacuum. The longer the radial dimension of the
space the greater the heat retaining capacity and the better
the temperature characteristics which can be obtained.
However, by setting the pressure of the space at 1 Pa or
less, the optimum heat retaining capacity can be obtained
while reducing the diameter of the low-pressure mercury
vapour filled discharge lamp 1.

Title: Sputter deposition and annealing of copper alloy metallization              M
Inventor: CHIANG TONY
IPC: C23C14/16
Filed: 1998-05-08
Abstract: A copper metallization structure and its method of formation in which a layer
(100) of a copper alloy, such as Cu-Mg or Cu-Al is deposited over a silicon oxide
based dielectric layer (64) and a substantially pure copper layer (102) is deposited
over the copper alloy layer (100). The copper alloy layer (100) serves as a seed or
wetting layer for subsequent filling of via holes (66) and trenches with substantially
pure copper and also provides barriers at the interfaces with the underlying dielectric
and the overlying pure copper. The copper alloy may be deposited cold in a sputter
process, but, during the deposition of the pure copper layer (102) or afterwards in a
separate annealing step, the temperature is raised sufficiently high to cause the
alloying element of the copper alloy to migrate to the dielectric layer (64).
Alternatively, the copper alloy may be deposited with the wafer held at an elevated
temperature. The alloying element that has migrated to the oxygen-rich surfaces
oxidizes to form thin stable layers (70), for example of magnesium or aluminum
oxide, that act as barriers there against diffusion of copper into and through the
dielectric layer (64). The inner barrier also promotes adhesion of the alloy layer to the
dielectric layer (64), thereby forming a superior wetting and seed layer for subsequent
copper full-fill techniques. Filling of the alloy-lined feature can be accomplished
using PVD, CVD, or electro/ electroless plating.

Abstract: The method involves comparison of the degree of depression of the accelerator pedal (103) with a threshold value. When the degree of depression lies above the threshold value this indicates a dynamic request or control input. The comparison process takes account of how the driver normally operates the accelerator pedal. This allows for the fact that for a mode of driving recognised as sporty a greater degree is necessary than in the case of one recognised as careful. Recognition of the different driving modes can be based on continuous recording of the depression of the accelerator pedal and a statistical evaluation in respect of the degree of depression.
