An intrinsic semiconductor material is chemically very pure and possesses poor conductivity.
It has equal numbers of negative carriers (electrons) and positive carriers (holes).
A silicon crystal is different from an insulator because at any temperature above absolute zero temperature, there is a finite probability that an electron in the lattice will be knocked loose from its position, leaving behind an electron deficiency called a "hole".
