Abstract: Exposure control method and apparatus particularly suitably usable in an X-ray exposure apparatus, for exposing a mask and a wafer to a radiation (X-rays) from a synchrotron to transfer a pattern formed on a mask onto the wafer, is disclosed. Shutter device for controlling passage and interception of the synchrotron radiation is provided between the synchrotron and the wafer. The shutter device includes a blade member having a leading edge and a trailing edge which are rectilinearly movable in a direction in which there exists non-uniformness in illuminance of the radiation. The leading edge is used to determine the timing of start of passage of the radiation to the wafer, while the trailing edge is used to determine the timing of interception of the radiation. The moving speeds of the leading edge and the trailing edge are controlled independently of each other to provide different exposure times for different portions of an exposure region on the wafer, in accordance with the non-uniformness in illuminance. By this, the amount of absorption of radiation by a resist material on the wafer can be uniformized throughout the exposure region.

Abstract: A shock absorber is provided with an arrangement for bringing about different kinds of damping characteristics, which are determinable with external controls (I), independently of whether the piston speed varies. The shock absorber comprises a piston which works in a cylinder (2) and which is provided with a passage between the upper and lower sides (1a, 1b) of the piston. The changes in the damping characteristics are obtained by a restriction in the aforementioned channel being influenced. The elements which influence the restriction work with a servo function, in which a first valve element (7) exerts an influence on the restriction by means of a first pressure which is created by means of a pilot flow running between the aforementioned upper and lower sides which is determinable with a second valve element (8) which is controllable by the aforementioned controls. The first valve element (7) comprises a spring-loaded pressure-operated slide, the position of which is in every instance of control counterbalanced by the aforementioned first pressure and a second pressure originating from the pressure difference existing between the upper and lower sides of the piston. The second valve element interacts with a proportional magnet which provides a setting of the first pressure independent of the variation in the piston speed.

Abstract: To avoid an electrically controlled gearbox breaking down in a vehicle without any chance for the driver to limp home, to a service depot, or even off the road, a detachable facility (50) is provided in the flex to shifting actuators which change the gears. An emergency unit can be manually connected in, and a rotatory switch can drive the shifting actuator to either of two neutral positions (N1,N2) which lie respectively at the end of a reverse gear alley (AR) and at the end of a forward gear alley (AF2). Preferably there is no forward gear alley opposite any reverse alley (AR) to minimise chances of erroneously, or accidentally, selecting a wrong direction. The two neutral positions (N1,N2) are consecutive positions on the switch. Either the only forward gear is catered for, or one (F1) of them, if there are more than one, is chosen to involve shifting actuators which are all different from those involved in selecting a reverse gear (R) catered for.

Abstract: The texture of a travelling web (20) is determined by instantaneously illuminating an area of the web via a strobe light (10) and photographing the illuminated area by a video camera (14) correlated to operate in conjunction with the strobe. The signal from the camera is digitized, histogrammed and analyzed to determine the characteristics of the web. The strobe light may direct the light through the web or at an angle to the web and the video camera depending on the characteristics to be determined may be positioned to receive specularly reflected light from the web or reflected light or positioned on the opposite side of the web to receive light transmitted through the web. In one embodiment the light is polarized and directed at Brewster's angle onto the surface of the web and only similarly polarized specularly reflected light is received by the camera.

Abstract: Cu (14) is deposited as a film on the surface of a single crystalline semiconductor substrate (18) of Si or Ge, while the substrate is held at room temperature. It has been found that the materials will react by themselves over an extended period of time to form a Cu-silicide (20) or Cu-germanide (46) compound interface. The process may be used to produce interconnection metallization for integrated circuits, but, in the context of existing VLSI processes, heat is used to accelerate the formation using the minimum desirable parameters of a temperature of about 150°C for about 20 minutes. Contrary to the belief in the art that Cu always diffuses in silicon, the resulting interface junction has been found to demonstrate superior (near ideal) current/voltage characteristics and can be used as a high temperature (600-800°C) stability Ohmic/Schottky contact to Si or as a Cu diffusion barrier. Additional embodiments involve a Cu layer on a Ge layer on Si substrate, a Cu layer on a Si x Ge 1-x  layer on Si substrate, and the use of an intermediate layer of a refractory metal such as W. Various other VLSI embodiments are also disclosed.
