Patent EP-0441164-A2 (EP)
Inventor: BREWER WILLIAM DEAN
IPC: H01L21/48
Filed: 1991-01-22
Abstract: The present invention comprises the use of a copper/ nickel containing alloy composition or application of a protective nickel alloy coating to copper current-carrying leads to prevent electrolytic migration between tape automated bonding (TAB) package leads. One embodiment of the invention comprises a substrate having adhered thereon a plurality of nickel-copper alloy current-carrying leads. Option-lly, an intermediate adhesion promoting layer is located between the substrate and the leads. 
     Another embodiment relates to electronic circuit packages comprising a substrate (11) and copper current-carrying leads (13) wherein the exposed area of the copper current-carrying leads is overplated with a more durable metal, such as a noble metal (14), to thereby enhance the circuits' corrosion resistance, solderability and bondability. This durable metal layer is in turn plated with a nickel-containing barrier layer (15). 
     By virtue of the alloy composition or the protective coating materials applied to the copper current-carrying leads in accordance with the present invention, electrolytic migration can be substantially reduced or eliminated.

Abstract: In order to improve the spatial resolution of a conventional scanning electron microscope at low electron energies and sufficiently large working distances, it is proposed to arrange an electrostatic immersion lens in the region of the intermediate image (ZB) produced by the condenser unit (KL). The immersion lens consists of a beam guiding tube (SR) at anode potential and a further tube electrode (RE) which is arranged insulated in the column of the scanning electron microscope, and to which a high positive potential is applied. Since the tube electrode (RE) reaches as far as into the region of the pole piece gap of the objective lens (OL), an electric field is set up here which brakes the electrons (PE) to the desired final energy. Due to the retardation field superimposed on the focusing magnetic field of the objective lens (OL), the lens has very small colour and opening error constants. In addition, the influence of the Boersch effect is substantially reduced owing to the high mean kinetic energy of the primary electrons in the column.

Abstract: In order to determine the nonlinear refractive index coefficient of a material which, once inserted into a Fabry-Perot cavity (1), has an optically bistable behaviour, the output power (l2; l3) of the cavity (1) is measured in function of the power (l1) of an amplitude-modulated optical input signal to obtain the material hysteresis loop; the hysteresis loop saturation region is detected, where the phase (φ) of the electromagnetic field associated with the signal within the cavity is a linear function of the output power; the values of the phase (φ) in said region are obtained from the output and input power values (l2, l3; l1) and the nonlinear refractive index coefficient (n2) is obtained from the angular coefficient of the straight line representing said phase (Fig. 1).

Abstract: Optical disk drive has a fine actuator (46) which holds an objective lens (45) and which is movably mounted on a head carriage (34). Servo systems connected to the head carriage (34) and the fine actuator (46) cause the fine actuator (46) to seek and track follow based upon signal recovered from a disk while the head carriage (34) is caused to follow the motions of the fine actuator (46). A tracking error signal is generated indicating the relationship of the beam supplied through the objective lens with respect to tracks on the record medium. An RPE signal (relative position error) is generated by an RPE detector which indicates the relationship of the relative motion of the fine actuator (46) to the head carriage (34). Both the relative position error and tracking error signal are calibrated as to offset and as to gain for providing a more precise servo positioning system.

Abstract: Low dielectric constant, high molecular weight polymers, e.g. polyimides, polyamides, polyesters and polyurethanes, are described.The fluorine containing constituents are sterically disposed so that the dipole moment of the constituents tend to cancel out. Since fluorine containing diamines are generally nonreactive, to achieve a polyimide of high enough molecular weight to be practically useful, a method of fabrication of a high molecular weight polymer from monomers of low reactivity is provided. The monomers, such as a diamine and dianhydride are provided in a solution within which a low molecular weight polyamic acid is formed. The solution is dried. The polyamic acid used is cured to a low molecular weight polyimide. The polyimide is redisolved, redried and recured enough times to build up the molecular weight to a useful level. The method is applicable to fabricating other polymers of high molecular weight, such as polyamides, polyesters and polyurethanes.

Abstract: In a radio signal detecting system, an antenna (1, 14, 51, 52) is rotatably mounted on a wrist watch type case (41, 71), and this antenna is manually rotated to receive a radio signal reflected from a target to be distance-measured every time the antenna is rotated by a preselected rotation angle. The reflected radio signal is digitally converted into field strength data, or distance data. These field strength data, or distance data are sequentially stored into a memory circuit (16, 61) in correspondence with the rotation angle of the antenna. Since the data stored into the memory circuit (16, 61) at every rotation angle for the antenna are displayed on a liquid crystal display unit (24, 64), the radio signal detecting system can be made compact and operated under low power consumption.
