Epitaxial Wafers : Growing a silicon ingot can take
anywhere from one week to one month, depending on many factors, including
size, quality and the end users specifications.
More than 75% of all single crystal silicon wafers are grown by the Czochralski
(CZ) method. CZ ingot growth requires chunks of virgin polycrystalline silicon.
These chunks are placed in a quartz crucible along with small quantities of
specific Group III and Group V elements called dopants. The added dopants give
the desired electrical properties for the grown ingot. The most common dopants
are boron, phosphorus, aresenic and antimony. Depending on which dopant is
used, the ingot becomes a P or N type ingot (Boron: P type; Phosphorus, Antimony,
Arsenic: N type). The materials are then heated to a temperature above the melting
point of silicon, 1420 degrees Celsius. Once the polycrystalline and dopant
combination has been liquefied, a single silicon crystal, the seed, is
positioned on top of the melt, barely touching the surface. The seed has
the same crystal
orientation required in the finished ingot. To achieve doping uniformity,
the seed crystal and the crucible of molten silicon are rotated in opposite
directions. Once conditions for the crystal growth have been met, the initial
crystal is slowly lifted out of the melt. Growth begins with a rapid pulling
of the first crystal in order to minimize the number of crystal defects within
the seed at the beginning of the growing process. The pull speed is then
reduced to allow the diameter of the crystal to increase. When the desired
diameter is obtained the growth conditions are stabilized to maintain the
diameter. As the seed is slowly raised above the melt, the surface tension
between the seed and the melt causes a thin film of the silicon to adhere
to the seed and then to cool. While cooling, the atoms in the melted silicon
orient themselves to the crystal structure of the seed. Epitaxial Wafers
