This paper is an overview of work in the IBM Microelectronics Division to extend electronbeam lithography technology to the projection level for use in next-generation lithography. The approach being explored—Projection Reduction Exposure with Variable Axis Immersion Lenses (PREVAIL)—combines the high exposure efficiency of massively parallel pixel projection with scanning-probe-forming systems...

Temporal aliasing artifacts are common in both computer generated and natural motion sequences. One of the most striking manifestations of temporal aliasing is the apparent reversal of motion commonly referred to as the "wagon wheel effect." In this paper, we examine temporal aliasing from the standpoint of joint spatiotemporal/spatiotemporal-frequency representations. We show that apparent mot...

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...

Let r 3 (n) be the number of representations of a positive integer n as a sum of three squares of integers. We give two distinct proofs of a conjecture of Wagon concerning the asymptotic value of the mean square of r 3 (n).

we find an explicit expression of the tutte polynomial of an $n$-fan. we also find a formula of the tutte polynomial of an $n$-wheel in terms of the tutte polynomial of $n$-fans. finally, we give an alternative expression of the tutte polynomial of an $n$-wheel and then prove the explicit formula for the tutte polynomial of an $n$-wheel.

  Background and aims: Noise pollution is one of the risk factors of the human environment that may seriously threat physical and mental health of human beings. One of the main sources of this type of pollution is the noise produced by urban transportation and traffic, particularly subway in the environment. This article aims at study and evaluation of the noise condition in drivers’ cabin and ...

This publication presents lithography results for 3D wafer-level system integration applications using a reticle free maskless VPG+ 400 from Heidelberg Instruments. The focus is on high density Cu redistribution layer (RDL) formation with <2µm L/S used in polymer RDL stacks, overlay accuracy determination better than ±150nm and hybrid bond interconnect 2µm interconnects, all processed 300mm ...
