X-ray lithography
E. Spille,R. Feder +1 more
TL;DR: The use of more than one X-ray source could fulfill the requirements imposed by mask making and device fabrication as discussed by the authors, which is a natural complement to electron beam pattern generation and photolithography seems to fill a need in the fabrication of submicron devices.
Journal ArticleDOI
Vertical path atmospheric MTF measurements
TL;DR: In this paper, a relatively simple photographic technique was employed to compile summaries of the atmospheric MTF characterized by the transverse coherence length r0 over a seven-month period during the day and night.
Journal ArticleDOI
X-ray lithography
TL;DR: A brief history of some of the world's major efforts in X-ray lithography is provided and a discussion of the potential future of the approach in microlithography is discussed.
Journal ArticleDOI
Daytime r(0) evaluated from vertical microthermal measurements.
TL;DR: In situ daytime r(0) measurements obtained from balloon-borne microthermal radiosondes are found to be log normal distributed at various levels aloft and that r( 0) follows a power law in the 100-10,000-m range.
Journal ArticleDOI
High tolerance to off-axis aberrations with a birefringent lens
TL;DR: In this paper, the imaging behavior of an optical system consisting of a lens made of a uniaxial birefringent crystal sandwiched between two linear polarizers with the introduction of prespecified off-axis aberrations such as astigmatism and coma was investigated.

The Frequency Response of a Defocused Optical System
TL;DR: In this paper, the response of a defocused aberration-free optical system to line-frequencies in the object is studied analytically, and curves are given showing the response as a function of line-frequency for a range of values of defect of focus.
Journal ArticleDOI
Microscope with Enhanced Depth of Field and 3–D Capability
TL;DR: In the summer of 1969, R. L. Gregory was working at Bell Labs, and suggested one might be able to increase the effective depth of field of a microscope if, instead of making the objective achromatic, one arranged that the different spectral colors come to foci at different distances from the lens.
Journal ArticleDOI
A solid-image microscope.
TL;DR: It seems unfortunate that Dr. MacKay's work was interrupted, and not made generally available, when he was working on his ‘solid image’ microscope.

Evidence for 62He ‘Clusters’ in Nuclei
L. H. Ahrens,R. D. Cherry +1 more
TL;DR: In this paper, the authors have presented a formal treatment of the behaviour of the α-particle states of the nucleus and illustrated it with particular reference to the nucleus 8 4Be considered as two αparticle clusters, and pointed out that stable closed shells such as those with neutron numbers, N, of 50 and 82, could be considered as large clusters.
