Orphan date November 2006 Context date October 2009 Stress Migration is a failure mechanism that often occurs in IC metallization aluminum , copper . Voids form as result of vacancy migration driven by the hydrostatic stress gradient. Large voids may lead to open circuit or unacceptable resistance increase that impededs the IC performance. Stress Migration is often referred as Stress Voiding , Stress Induced Voiding or SIV . High temperature processing of copper dual damascene structures leaves the copper with a large tensile stress due to a mismatch in coefficient of thermal expansion of the materials involved. The stress can relax with time through the diffusion of vacancies leading to the formation of voids and ultimately open circuit failures. ref Stress Migration and the Mechanical Properties of Copper, G.B.

Branch migration describes the ability of a DNA strand partially paired with its complement in a duplex to extend its pairing by displacing the resident strand with which it is homologous. This usually happens when two homologous double strands form a Holliday junction and the whole structure slides into one direction the branch migrates . This procedure can influence the amount of information that is transferred between two recombining partners. In E. Coli RuvA and RuvB of the RuvABC protein complex promote branch migration until RuvC binds and resolves the Holliday junction by cleaving. Another definition for branch migration is the extension of a D loop when a single stranded DNA strand invades a recipient duplex during recombination or repair.

Assisted migration is the practice of deliberately populating members of a species from their present habitat to a new region with the intent of establishing a permanent presence there, generally in response to the degradation of the natural habitat due to human action. The human action most frequently considered is climate change, but assisted migration can be in response to habitat loss or other impacts to historic range. Assisted migration flies in the face of conventional management approaches that attempt to re establish habitat corridors that allow species to disperse in response to a changing climate.

Unreferenced date February 2007 Job migration is a term that has gained widespread use in the recent years and although it means relocation of employment jobs from one geographical area to another, it has come to symbolize the migration or relocation of jobs to other countries. Reasons for job migration In most situations jobs are moved from one location to another, or to multiple other locations, because of changes in one or many of the following supply and demand for products and services, business conditions, labor markets, government policies, political reasons, competition, environmental conditions, local business costs, technological obsolescence, outsourcing , higher productivity , etc. Impact of job migration Job migration must not lead to a rise in unemployment , if national labour markets are flexible enough. Whether the native population can expect gains or losses from immigration depends, among other things, on the size and the structure of the immigration flow and the labour market institutions in the receiving countries i.e. wage flexibility .
