With an eye toward the future in environmentally friendly lead-free electronics, a majority of the papers concentrated on the microstructural evolution and mechanical properties of the various viable lead-free solders. Twenty-three of forty-seven papers presented at the symposium appear in this volume. This symposium was the second in a series devoted to advanced research in thin-film materials and processes for microelectronic systems of submicron-size features. With 25 invited and contributed presentations, this symposium provided an interactive forum for multidisciplinary discussions on the science and technology of advanced materials and processes, and critical reliability issues in microelectronic device fabrication.
Topics discussed in this special issue include recent advances in silicon device processing, electromigration reliability studies on damascene Cu interconnects, an in-situ electron microscopy investigation on mechanical properties of nano-scale thin films, fundamental understanding of chemical mechanical planarization, and experimental and simulation studies on thin-film microstructure evolution. Thirty-one of forty-seven papers presented at the workshop appear in this volume. Goetze died on January 17, in Bad Zwesten, Germany at the age of 76 after suffering a severe stroke a month earlier.
Anderson, manager of the applied physics department of Westinghouse Research Laboratories stated that, "a new electronic tube, so sensitive it can "see" individual particles of light, has enabled Westinghouse scientists to photograph the faint tracks of Cosmic ray as they move through solid crystal at speeds near the velocity of light. It had the capability to produce clear images in motion at low light levels without motion distortion. The SEC tube had DoD highly top secret security classification  but was the only device that could meet the Apollo camera mission requirements to operate in both lunar day and night.
The SEC tube was used to build a camera to transmit live images from the moon to earth on Apollo The tube was also employed in science in electron microscope biological tissue study; ground based astronomy, material testing and inspection of integral circuits in industry, and security and police.
The Apollo 12 lunar camera sustained damage when it was inadvertently pointed directly towards the sun damaging its sensor. Goetze oversaw the development of the Mars camera. May - Apollo 10 crew send first color television pictures from outer space to earth . July — Television pictures of man's first steps on the moon.
Through joint efforts, one quarter of the population of the earth was able to see the first steps of the first men on the moon. Life Magazine estimated that million people watched the first step on the moon by Armstrong. Images of the flag-planting ceremony passed through the fixed-focus lens of the camera, were transformed into electrical impulses, amplified a hundred times and beamed directly to earth.

The MTF is determined by the pitch and the degree of thermal isolation between islands. For a particular groove width the heat flow between islands is determined by the thermal conductivity of the support layer multiplied by its thickness.
In his analysis of the thermal properties of reticulated layers, Watton 4 has derived the MTF at high spatial frequency as a function of the conductivity-thickness product of the support film.
These results are given in Fig. For optimum performance, it is necessary to Teticulate the target to its full thickness. Target thickness is not always uniform, and in obtaining full reticulation of the thick ct areas, the signal plate on thin areas can surfer prolonged exposure to the ion beam.
To prevent perforation of the thin nichrome signal plate the layer of oxide shown in Fig. Masks for Etching Ion beam masks for etching have been made in evaporated aluminium.
The etch rate of aluminium appears to be reduced in the presence of DTGS etch products. The masking patterns have been formed by the evaporation of aluminium from a small source through a fine metal mesh held in contact with the target surface. Reticulated target cross section. The variation of MTF high spatial frequency with the thermal conductivity- thickness product of the support film. Unfortunately, the mesh can easily become distorted when heated by radiation from the evaporation filament. This leads to uncontrolled varia- tion of groove width, which can produce background shading in the tube.

As an alternative, photoresist techniques may be used to produce the etch masks, which involves more handling of the target, but does allow good dimensional control. These targets are significantly less robust than silicon slices and have, therefore, required the develop- ment of special handling techniques.
