The deactivation energy of phosphorus, boron and antimony at a growing silicon film surface is -13 eV, -5 eV and -10 eV respectively as shown in Table 1. Since the deactivation energy of boron is extremely small (< 5 eV), ion bombardment energy must be precisely controlled to be lower than 5 eV in order to make the activation ratio of dopants 100 %. The experimental results of plasma-induced deactivation energy of dopants will be crucial value for plasma processing, especially for low temperature processing using ion bombardment processes. Figure 1 schematically shows an rfdc coupled mode bas sputtering system [l] used in silicon epitaxy. The kinetic energies of ions incident on the target and the substrate were independentlly determined by two external dc voltages applied to the sputtering target and the substrate, respecitiiely. Prior to the film deposition, in situ surface cleaning [1,3] under the optimized condition was carried out to remove physically adsorbed molecules onto the wafer surface during the air exposure in a clean room. The deposition rate was controlled to be 10 ndmin in this work. The sputtering target material was phosphorus (2-3x10‘’ cmS), boron ( 6 ~ 1 0 ’ ~ cmS) antimony ( 3 ~ 1 0 ’ ~ cmS) doped silicon. The crystallinity of grown silicon films was evaluated by reflective high energy electron diffraction (RHEED) analysis. The resistivrty of the in situ doped epitaxial silicon film was measured by a four-point probe method. Figure 2 shows the resistivity of a silicon film deposited using the antimony doped silicoin target as a function of the ion bombardment energy. The substrate temperature was kept at 3150’C during the deposition. Normalized ion flux which is defined as the number of bombarding argon ions per each deposited Si atom is the same in all points. In region (I), ion bombardment energy is not enough to enhance silicon film growth. Crystal structure of the grown film is polycrystal or aimorphous. Increase of resistivlty is caused by this degraded crystallinity. This situation is schemalically illustrated in Fig. 3(1). In region (II), antimony impunty was fully activated and perfect single cirystal was achieved. Kikuchi lines were observed in the RHEED photograph. It indicates that the crystallinlty of the as-deposited silicon epitaxial layer is high quality single crystal. This is also illustrated in Fig. 3(11). In region (Ill), antimony impurity was not fully activated in the as-deposited silicon epitaxial layer. However, the RHEED photograph showed Kikuchi lines. This clearly shows that antimony is unstable at growing silicon surface and easily displaced from lattice site by ion bombardment higher than -10 eV. This situation is illustrated in Fig. 3(111).

These nanocrystals emit luminescence that usually doesn't appear in the bulk materials. For fabrication technique of these nanocrystals, ion implantation is a good candidate in that it produces a controlled depth distribution of desired species and is extensively used in semiconductor technology. In this work, we present possible luminescence origins observed from Ge implanted Si02 layers. The Si02 layer with a thickness of 300 nm was grown by wet oxidation of Si(100). Ge negative ions were implanted into Si02 layer at room temperature(RT) with an energy of 100 keV. The employed dose of Geion was 5 X 10l6 ions/cm2. After implantation, the samples were annealed in nitrogen ambient for 2 hour at various temperatures. X-ray photoelectron spectroscopy(XPS) measurements were performed using a standard A1 K a (1486.7 eV) excitation source in an electron spectrometer ESCA 5700(PHI Ldt.) at a residual gas pressure of 2 X lo-'' torr. The photoemitted electrons were detected by hemispherical analyzer with a pass energy of 23.5 eV. Photoluminescence spectra were obtained at RT in a conventional way. An Ar-ion laser (457.9 nm) was used as an excitation source and the luminescence was detected by a cooled photomultiplier tube employing the photon counting technique. Figure 1 shows the PL spectra of an as-implanted sample and samples annealed for 2 hours at 900, 1000, and 1100 \"C . After annealing at 900 \"C in nitrogen ambient for 2 hours, the PL peak around 2.0 eV observed from as implanted sample disappeares. It implies that the luminescence from the as-implanted sample is related to some radiative defects formed by Ge implantation. However, after annealing at temperature higher than 900 C , the luminescence with the same peak position as that of the as-implanted sample shows up again, and its intensity increases with temperature. Hence, the PL from the annealed sample should be regarded as a luminescence emitted from the Ge nanocrystal. Similar results of luminescence from Ge nanocrystals were reported by others.[ 1,2] In order to confirm the origin of PL, we carried out XPS analysis for both asimplanted sample and the other samples annealed at 1 100 \"C . In the case of the asimplanted sample, Ge-0 bond appears dominant, but the annealed sample shows mainly Ge-Ge bond with small amount of Ge-0 bond near the projected range of iplanted Ge.","PeriodicalId":356908,"journal":{"name":"Digest of Papers.
