Abstract: Penetrators and methods of manufacturing penetrators are disclosed. One method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) cold heading a piece of material to form a blank; (b) machining the blank to create the arrowhead geometry; and (c) roll forming the blank to create the base geometry. Another method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) machining a piece of material to create the arrowhead geometry; and (b) roll forming the piece of material to create the base geometry. Yet another method of manufacturing a penetrator from a blank includes the steps: (a) machining the blank to create a first surface feature of the penetrator; and (b) roll forming the blank to create a second surface feature of the penetrator.

Abstract: Estimating impedance of energy storage devices includes generating input signals at various frequencies with a frequency step factor therebetween. An excitation time record (ETR) is generated to include a summation of the input signals and a deviation matrix of coefficients is generated relative to the excitation time record to determine crosstalk between the input signals. An energy storage device is stimulated with the ETR and simultaneously a response time record (RTR) is captured that is indicative of a response of the energy storage device to the ETR. The deviation matrix is applied to the RTR to determine an in-phase component and a quadrature component of an impedance of the energy storage device at each of the different frequencies with the crosstalk between the input signals substantially removed. This approach enables rapid impedance spectra measurements that can be completed within one period of the lowest frequency or less.

Abstract: A wafer processing cluster tool, having one or more electron beam exposure modules receives wafers from the tool transport mechanism at the internal vacuum pressure of the machine. The loading, unloading, handling and processing of wafers in the machine can occur while other wafers are being treated. The cluster tool has a transport module enclosing an internal volume continuously maintainable under vacuum, a plurality of ports and a wafer transport mechanism for selectively transferring wafers among processing modules. The processing modules perform wafer processing therein under vacuum. At least one semiconductor wafer processing module is an electron beam radiation module. The tool further has a loading module and an unloading module attached to the transport module which are capable of inserting and removing wafers into and out of the transport module from an external environment.

Abstract: An electrostatic holding device for holding semiconductor wafers and similar materials during microelectronic device manufacturing operations. It has a circular, electrically conductive wafer support having a rounded periphery; an annular border region; and a flat, concentric, raised, central plateau having an electrically conductive top surface. The plateau has a tapered circumferential edge which extends down to the annular border region. A nonelectrically conductive coating is on the rounded periphery, the border region and the tapered edge which extends to, but does not cover, the conductive top surface of the central plateau such that an the coating is coplanar with the conductive top surface of the central plateau. A removable dielectric sheet overlies the top surface of the central plateau, the coating on the tapered edge and the coating on the border region.

Abstract: A microfilm reader is provided which not only permits an operator to visually examine previously created images, stored on microfilm, but also to create a digitized representation of the image being viewed. The reader includes an opto-mechanical system for displaying a selected image and also for directing the image to a digitizing sensor. The sensor is coupled to electronic circuitry for storing the digitized representation either in black and white form or with a gray scale. The contents of the storage unit can be accessed a microcomputer coupled to the reader for purposes of manipulating the digitized representation or for transmitting it to another display or an output device, such as a facsimile machine.
