Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was undertaken to examine the feasibility of using ion-implanted filaments doped with either an alkali metal or noble gas for in situ recalibration of onboard mass spectrometers during extended space missions. Implants of rubidium and krypton in rhenium ribbon filaments were subsequently tested in a bakeable 60 deg sector mass spectrometer operating in the static mode. Surface ionization and electron impact ion sources were both used, each yielding satisfactory results. The metallic implant with subsequent ionization provided a means of mass scale calibration and determination of system operating parameters, whereas the noble gas thermally desorbed into the system was more suited for partial pressure and sensitivity determinations.

Download or read book Ion Implantation in Microelectronics written by A. H. Agajanian and published by Springer. This book was released on 1981-09-30 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past ten years the use of ion implantation for doping semiconductors has become an active area of research and new device development. This doping technique has recently reached a level of maturity such that it is an integral step in the manu facturing of discrete semiconductor devices and integrated circuits. Ion implantation has significant advantages over diffusion such as: precision, purity, versatility, and automation; all of which are important for VLSI purposes. Ion implantation has also found new applications in magnetic bubble domain materials, superconductors, and materials synthesis. This book is a comprehensive bibliography of 2467 references of the world's literature on ion implantation as applied to micro electronics. This compilation will easily enable researchers to compare their work with that of others. For easy access to the needed references, the contents are divided into fifty-two subject headings. The main categories are: bibliographies, books and symposia, review articles, theory, materials, device applications, and equipment. An author index and a subject index are also given to provide easy access to the references. The literature from January 1976 to December 1980 is covered. The literature prior to 1976 is the subject, in part, of a previous book by the author (1). The main sources searched were: Physics Abstracts (PA) , Electrical and Electronics Abstracts (EEA) , Chemical Abstracts (CA) , Nuclear Science Abstracts (NSA) , and Engineering Index. The volumes and numbers of the abstracts are given to pro vide access to the abstracts.
