High energy (MeV) Cu ions were implanted into n-type Si samples at angles of 7 degrees, 30 degrees, 45 degrees, and 60 degrees. The doses were 5X10(14) and 2X10(14) ions/cm(2). The damage profiles in Si(100) were investigated by a Rutherford backscattering/channeling technique with 2.1 MeV He ions. The longitudinal damage straggling and lateral damage spread are estimated for 1.0 MeV Cu+ implanted in Si(100). The values obtained are compared with the TRIM (transport of ions in matter) code. The results show that the longitudinal damage straggling is found to be in good agreement with the calculated one within 13% by use of the TRIM code, but the experimental value of the lateral damage spread is higher than the calculated one by about 28% using the TRIM code. The effect of dose rate, energy, and dose on damage distribution is investigated also.
