The philosophical and practical differences between Japanese and US IC industries in regard to VLSI reliability, as well as recent research topics and new analysis methods such as wafer scale testing, are discussed. It is suggested that a new approach to VLSI reliability is needed in response to the paradigm shift being brought about by simple scaling limitations, increased process complexity and application of VLSI to advanced systems. An example of this shift is the movement from simple failure analysis by sampling the output of a manufacturing line to the building-in-reliability approach. To introduce and expand on the building-in reliability approach in VLSIs, the authors discuss the required deeper physical understanding of such important processes as hot-carrier effects, dielectrics and metallization.>

This paper proposes a new signal smoothing method which is applicable to any type of signal. This method is a direct extension of the Lanczos signal smoothing method for the truncated Fourier series. The method coincides with the classical Lanczos method if basis functions of a signal space are trigonometric functions. The proposed method is applied to the smoothing for the truncated series of the Hermite functions which are the eigenfunctions of the Fourier transformation.
