Laser annealing technology
Laser annealing is used in the production of semiconductor products and consists in obtaining an equilibrium structure in their thin near-surface layers.
Two variants of the considered technology are used: using continuous or pulsed laser radiation. Heating has a local character, and is not accompanied by thermal damage or structural change in adjacent areas of the product. As a result, local melting of the material takes place, in which the active ions of certain elements (boron, arsenic, phosphorus) are introduced into the basic structure, mainly silicon. As a result of the recrystallization, the chemical composition and properties of the surface films of the semiconductor change in the necessary direction, and the internal stresses are also removed.
The laser annealing mode is determined by:
- Processed material;
- The volume density of the thermal power of the laser;
- The state of the crystal lattice;
- The initial thickness of the surface film.
To buy effective technologies for the production of laser annealing semiconductor products is offered by Electrovek-Steel. Products are sold at economically favorable prices of the manufacturer. The supplier ensures timely delivery to the customer of all components of the laser annealing process
The main requirements for an annealing laser are:
- Possibility of very precise focusing of the laser spot;
- Ability to apply various filler materials to the surface of the product;
- Ensuring the necessary heat density with the minimum amount of time required to complete the operation.
For laser annealing, it is advisable to use pulsed laser units operating on inert gases-krypton or argon.
Electrovek-steel company offers to purchase at the manufacturer’s prices modern equipment and consumables for laser annealing. The supplier guarantees the timely delivery of products to the point set by the consumer.
