Non-alloyed, refractory metal contact optimization with shallow implantations of Zn and Mg

Refractory metal contacts to GaAs show great promise for stability during high-temperature processing and for high-reliability. In this paper the authors report a study of sputtered tungsten and tungsten silicide contacts to ion implanted p-GaAs with both Zn and Mg implantations. This study focused on refractory contacts to shallow implanted contact layers that are suitable for devices such as JFETs and HBTs. The very different energy loss mechanisms of Zn and Mg ions result in different levels of implant damage which is studied by varying anneal temperatures and measuring the effects on contact and sheet resistances with the transmission line method. For the fabrication schemes investigated, specific contact resistivity versus anneal temperature with implant doses from 1 {times} 10{sup 14} to 5 {times} 10{sup 15} cm{sup {minus}2} are found to vary from non-ohmic to 10{sup {minus}7} {Omega}-cm{sup 2}. Low resistance contacts to shallow (<800 {angstrom}) implanted layers are achieved.

Natural gas monthly, March 1994

The Natural Gas Monthly (NGM) is prepared in the Data Operations Branch of the Reserves and Natural Gas Division, Office of Oil and Gas, Energy Information Administration (EIA), US Department of energy (DOE). The NGM highlights activities, events, and analyses of interest to public and private sector organizations associated with the natural gas industry. Volume and price data are presented each month for natural gas production, distribution, consumption, and interstate pipeline activities. Producer-related activities and underground storage data are also reported. From time to time, the NGM features articles designed to assist readers in using and interpreting natural gas information.

Input and decayed values of radioactive solid wastes buried in the 200 areas through 1971 (open access)

Input and decayed values of radioactive solid wastes buried in the 200 areas through 1971

Solid radioactive wastes resulting from chemical separations processing of spent reactor fuels have been disposed by burial in trenches in the 200 Areas since 1944. Solid radioactive wastes from other Hanford facilities and from off-site AEC contractors have also been buried in the 200 Areas` Waste Burial Grounds. Since 1970, industrial wastes containing or suspected of containing transuranic radionuclides have been packaged in concrete boxes and {open_quotes}dry wastes{close_quotes} have been packaged in steel boxes or drums and buried in segregated trenches. A land area of approximately 149 acres has been used to bury 5.2 million cubic feet of contaminated solid waste through calendar year 1971. Annual reports of radioactive solid waste burials issued, beginning in 1968, have shown land area used, and volume and quantity of radioactivity grams U and/or Pu and curies buried. No corrections for radioactive decay have been reported. In July 1972, J. D. Anderson, G. L. Hanson, G. R. Kiel, B. J. McMurray, and N. P. Nisick were assigned the responsibility for a study to provide the decayed inventory of radioactivity in each solid waste burial ground in the 200 Areas. The results of this study are included as Tables 1 and 2 in this report.
