A Faraday cup dosimetry system was developed and characterized to address the issues of plasma immersion ion implantation (PIII) dose measurements. Pure ion current was measured by using an electrostatic suppression mechanism combined with high-bandw

Charge control during the source-drain implants in the CMOS process is critical to avoid damage to the thin gate dielectric. PIII has always been touted as having good charge control, since the charge deposited on the gate during the implant pulse is

We present secondary electron yield and plasma enhancement factor data for silicon surfaces exposed to Ar, He, N2, O2, H2, and BF3 plasmas, for incident ion energies from 0.5–10 keV. A fiber-optic isolated Faraday cup was used to directly measure t

Recent developments in device architecture and the continuing search for tighter process control have driven the requirement for no energy contamination, high accuracy dose control, more precise angle control and peak dose rate control. The new high

Many applications of ion sources (e.g., ion implantation in the semiconductor industry) are very sensitive to particles and have tight specifications on allowable particle number and size. Among the sources of particles are the ion source itself (due
Measurement and analysis of deposition-etch characteristics of BF3 plasma immersion ion implantation

The deposition-etch characteristics of BF3 plasmas were quantitatively measured and analyzed using a deposition monitor, and were correlated with plasma parameters. It was found that by controlling pressure and rf power, the source could be operated

In plasma immersion ion implantation, the wafer is negatively pulsed while immersed in a dc ambient plasma. During this high voltage pulse, the sheath expands, and plasma ions are accelerated to the wafer. The essential character of this plasma sheat

A computer model capable of analyzing electrostatic lenses, including the effects of space charge, yet simple enough to run an entire beamline system calculation in seconds, has been developed and applied to VSEA’s latest high current beamline. Suc

Much has been published recently stating the effectiveness of plasma immersion ion implantation (PIII) in producing ultra-shallow junctions (USJ). Although PIII is capable of producing USJ implants as effectively as conventional mass-analyzed ion imp
