Abstract: An apparatus and method for the real-time, in-line testing of semiconductor wafers during the manufacturing process. In one embodiment the apparatus includes a probe assembly within a semiconductor wafer processing line. As each wafer passes adjacent the probe assembly, a source of modulated light, within the probe assembly, having a predetermined wavelength and frequency of modulation, impinges upon the wafer. A sensor in the probe assembly measures the surface photovoltage induced by the modulated light. A computer then uses the induced surface photovoltage to determine various electrical characteristics of the wafer.

Abstract: An ABS sensor bracket made up of two mounting wing plates engaged to a sensor receiver. The sensor receiver is generally cylindrical and is mounted between the wing plates such that the sensor receiver is asymmetric axially relative to the caliper anchor plate. When viewed from the side, there is a shorter end of the sensor receiver jutting out a shorter distance from the wing plates than an opposite longer end of the sensor receiver. In one embodiment, a first end of the sensor receiver has an outer diameter circumference greater than that of the opposite second end. The caliper anchor plate has an outer edge slot for mounting of the ABS sensor brackets. The outer edge slots are generally ‘U’ or ‘V’ shaped. There are mounting holes in the outer radial areas bordering the outer edge slots.

Abstract: An electrical connection, preferably for ALS sensors incorporated in wheel bearings, is installed coaxially on the wheel bearing and its side surface. It is equipped, for example, with slip rings which operate in conjunction with the electrical contacts of the ALS sensor which is solidly attached to the wheel bearing. This simplifies the manufacture and handling of the wheel bearing during transportation and assembly. In particular, the risk of damage to the connecting cord is reduced during operation.
