摘要： An assembly for measuring a trench depth parameter of a workpiece is disclosed. The assembly has an ultra-violet radiation source; a split fiber bundle having a first branch for propagating the ultra-violet radiation from the radiation source to a lens, and a second branch; a lens for focusing the UV radiation to the workpiece and refocusing an ultra-violet interference signal to the second branch; and a detector responsive to the ultra-violet interference signal received through the second branch. The detector transforms the ultra-violet interference signal to an electrical signal which is a measure of a trench depth of the workpiece. The ultra-violet interference signal is developed when ultra-violet radiation propagates through the workpiece and reflects from its base region to thereby interfere with ultra-violet radiation that is directly reflected by a workpiece surface which is different from the base region.

摘要： An electronically scannable multiplexing device is capable of addressing multiple bits within a volatile or non-volatile memory cell. The multiplexing device generates an electronically scannable conducting channel with two oppositely formed depletion regions. The depletion width of each depletion region is controlled by a voltage applied to a respective control gate at each end of the multiplexing device. The present multi-bit addressing technique allows, for example, 10 to 100 bits of data to be accessed or addressed at a single node. The present invention can also be used to build a programmable nanoscale logic array or for randomly accessing a nanoscale sensor array.

摘要： The invention discloses in one embodiment a parallel probe array (N×M) incorporating thermal near-field heaters (or writers) as well as magnetic sensors (or readers), which can be moved en bloc as well as independently of each other. To this end, the present invention uses a suitable controlling electronics for coordinating a parallel or quasi-parallel reading/writing, as well as controlling the positioning of an individual probe in an array. The control electronics enables the addressing of an individual or preselected set of probes, for controlling reading and/or writing, thereby securing the considerable advantage of versatility and efficiency of reading/writing in a parallel operation mode.
