Ion Implanted

A scanning probe microscope with a 80 nm radius diamond tip was used to investigate the wear resistance of single-crystal silicon and N+-implanted silicon. The N+ implantation conditions were 35 to 150 keV and 5 × 1016 ions/cm2. The N+ concentration depth profile was analyzed by using secondary ion mass spectrometry, and the chemical structure of N+-implanted silicon was also analyzed by using x-ray photoelectron spectroscopy. The following results were obtained. The maximum N+ concentration on the ion-implanted silicon shifted further below the surface and the thickness of the high ion concentration region increased with the implantation energy. The high N+ concentration region using multiple energies of 35–150 keV during the same ion implantation process was wider than that for the N+-implanted silicon using a single energy. The wear resistance of ion-implanted silicon was higher than that of single-crystal silicon. The N+-implanted silicon using multiple energies during the same ion implantation process showed higher wear durability than that of the N+-implanted silicon using a single energy. The Si2p spectrum of the high N+ concentration region implied a structure similar to a Si3N4 film, which resulted in higher wear resistance.

Oxygen Ion Implantation

The formation of buried oxide structures in single crystal silicon by high-dose oxygen ion implantation has received considerable attention recently for applications in advanced electronic device fabrication. This process is performed in a vacuum, and under the proper implantation conditions results in a silicon-on-insulator (SOI) structure with a top single crystal silicon layer on an amorphous silicon dioxide layer. The top Si layer has the same orientation as the silicon substrate. The quality of the outermost portion of the Si top layer is important in device fabrication since it either can be used directly to build devices, or epitaxial Si may be grown on this layer. Therefore, careful characterization of the results of the ion implantation process is essential.

Buried Layers

Buried TiSi2 layers, about 600Å thick and 900Å below the surface, were formed in < 111> silicon by ion implantation. The implantation was done with either 120 or 170 keV Ti+ to doses ranging from 5 x 1016 to 2 x 1017 ions/cm2, and at temperatures of between ambient and 650° C. Annealing was done at 600° C, 700°C and 1000°C. Continuous buried layers were achieved only with samples implanted with doses equal or greater than 1017 ions/cm2 and at temperatures above 450°C. Below this dose TiSi2, was present only as discrete precipitates. For room temperature implants, the TiSi2, layer is formed on the surface. The damage present consists of dispersed TiSi6 precipitates and microtwins.

ABSTRACTIn this paper is reported the development and implementation of a new local electronic stopping model for arsenic ion implantation into single-crystal silicon. Monte Carlo binary collision (MCBC) models are appropriate for studying channeling effects since it is possible to include the crystal structure in the simulators. One major inadequacy of existing MCBC codes is that the electronic stopping of implanted ions is not accurately and physically accounted for, although it is absolutely necessary for predicting the channeling tails of the profiles. In order to address this need, we have developed a new electronic stopping power model using a directionally dependent electronic density (to account for valence bonding) and an electronic stopping power based on the density functional approach. This new model has been implemented in the MCBC code, UT-MARLOWE The predictions of UT-MARLOWE with this new model are in very good agreement with experimentally-measured secondary ion mass spectroscopy (SIMS) profiles for both on-axis and off-axis arsenic implants in the energy range of 15-180 keV.

Silicon Membranes

ABSTRACTSelf-supporting, thin single crystal membranes can be fabricated from silicon wafers using ion implantation, anodic etching and subsequent annealing. Typically, membranes approximately 1200Å thick and about 250μm in diameter are formed in wafers 4 mil thick. Discs surrounding the membranes can be cut out to provide suitable TEM samples. In this paper, the steps for preparing such samples are presented with as much attention paid to experimental details as possible.

AbstractHighly conductive p+-polysilicon films were fabricated over Si(100) and SiO2 surfaces using high-dose ion implantation and rapid thermal annealing. Resistivities close to that of single crystal silicon were achieved. These films were characterized by a variety of electrical and optical techniques as well as SIMS and cross-section TEM.
