Ion implantation has been the dominating doping technique for silicon integrated circuit for past 30 years. It is expected to remain as the mean for doping technique for the foreseeable future. Like diffusion process, it is a process where dopant is introduced using ion species such as BF3 and PF5. The ion species are ionized

Advantages of Ion Implantation. • Precise control of dose and depth profile. • Low-temp. process (can use photoresist as mask). • Wide selection of masking materials. e.g. photoresist, oxide, poly-Si, metal. • Less sensitive to surface cleaning procedures. • Excellent lateral dose uniformity (< 1% variation across 12" wafer) n+.

3.5 Ion-Implantation and Diffusion Diffusion and Ion Implantation are the methods by which impurity is introduced into silicon to change its resistivity. These processes allow the formation of sources and drains of MOSFETs and active regions of bipolar transistors. In diffusion (in a high temperature environment) the dopant
In ion implantation, dopant atoms are volatilized, ionized, accelerated, separated 9.1 Ion Stopping. As each implanted ion impinges onto the target, it undergoes a series of collisions with the host atoms until it finally stops at some depth, .. technologies employing laser heating or other means expose the wafer to a high.
