anneal

 [ah-nēl´]
1. to heat a material, such as glass or metal, followed by controlled cooling to remove internal stresses and induce a desired degree of toughness, temper, or softness of the material.
2. to homogenize an amalgam alloy ingot by heating it in an oven.
3. to heat a material, such as gold foil, to volatilize and drive off impurities from its surface, and to increase its cohesive properties.

an·neal

(an-nēl'),
1. To soften or temper a metal by controlled heating and cooling; the process makes a metal more easily adapted, bent, or swaged, and often less brittle.
2. In dentistry, to heat gold leaf preparatory to its insertion into a cavity, to remove adsorbed gases and other contaminants.
3. The pairing of complementary single strands of DNA; or of DNA-RNA.
4. The attachment of the ends of two macromolecules, for example, two microtubules annealing to form one longer microtubule.
5. In molecular biology, annealing is a process in which short sections of single-stranded DNA from one source are bound to a filter and incubated with single-stranded, radioactively conjugated DNA from a second source. Where the two sets of DNA possess complementary sequences of nucleotides, bonding occurs. The degree of relatedness (homology) of the two sets of DNA is then estimated according to the radioactivity level of the filter. This technique plays a central role in the classification of bacteria and viruses. Synonym(s): nucleic acid hybridization
6. To renature proteins or polynucleic acids by slow cooling.

anneal

/an·neal/ (ah-nēl´)
1. to toughen, temper, or soften a material, as a metal, by controlled heating and cooling.
2. in molecular biology, to cause the association or reassociation of single-stranded nucleic acids so that double-stranded molecules are formed, often by heating and cooling.

anneal

Etymology: AS, aelan, to burn
1 to temper metals, glass, or other materials by controlled heating and cooling to make them more malleable and ductile.
2 to cause the interaction of two separate strands of nucleic acid to form a duplex molecule, often by using a related technique of controlled heating and cooling.

an·neal

(ă-nēl')
Process by which oligonucleotides affix to targeted DNA sequences.

In dentistry, to heat gold leaf preparatory to its insertion into a cavity to remove adsorbed gases and other contaminants.
[A.S. anaelan, to burn]

anneal (anēl´),

n (homogenizing heat treatment, softening heat treatment), the softening of a metal by controlled heating and cooling.
anneal foil,
n a process of subjecting noncohesive foil to heat to volatilize a protective gaseous coating on its surface, thus leaving the surface clean, making it cohesive.
anneal glass,
n a process of regulated heating and subsequent cooling to remove strain hardening or work hardening of glass.
anneal metal,
n a process of regulated heating and subsequent cooling to remove strain hardening or work hardening of metal.

In order for these specific primers to anneal, the template material must be single-stranded (ssDNA).
This makes the nascent strand ssDNA, allowing the opposing primer (Primer l in Figure 2c) to anneal, and DNA polymerase to again start strand synthesis.
Where no product is formed, the probe cannot anneal and is chemically degraded by the detection procedure without emitting a signal.
The Vantage Astra system's novel, laser-based architecture sets new standards for production-worthiness and provides a compelling value proposition for advanced anneal applications.
The customer is using the Summit systems for all annealing processes in the 130nm technology node, as well as for development of next-generation advanced silicide anneal applications beginning in the 90nm technology node.
Rapid ramp (250(degree)C/s) and cool-down (90(degree)C/s) rates limit thermal exposure of the wafer to less than 3 seconds above 950(degree)C for a 1050(degree)C spike anneal.
Hollands continued, "Specifically, the AST 3000's ability to offer superior temperature measurement and control capabilities, along with excellent temperature uniformity for fast-ramp spike anneals -- all backed by STEAG's strong service and support presence in Taiwan -- were critical factors in these two purchasing decisions.
Introduced in 1998, the AST 3000 is the industry's only RTP tool capable of spike anneals with ramp rates over 300(Degree) C/second, along with ramp-down rates of more than 80(Degree) C/second.
The system provides a full suite of leading edge applications that include silicides, TiSi2 or CoSi2; implant anneals, ultra-shallow junctions without "spike anneals"; high k dielectric anneals (Ta2O5, BST, SBT); glass reflow and/or densification (BPSG, PSG); curing of low k films; and low-temperature copper anneal.
These include transition-critical applications such as advanced dielectrics, pre- and post-tantalum pentoxide anneals, cobalt silicide, source/drain anneals, implant annealing, silicides, thin oxides and nitrides.
The significance of this feature has been verified at TI by demonstrated device speed and performance improvements for implant and silicide anneals.
