Zirconium-doped tantalum oxide high-k gate dielectric films
No full textA new high-k dielectric material, i.e., zirconium-doped tantalum oxide (Zr-doped TaOx), in the form of a sputter-deposited thin film with a thickness range of 5-100 nm, has been studied. Important applications of this new dielectric material include the gate dielectric layer for the next generation metal-oxide-semiconductor field effect transistor (MOSFET). Due to the aggressive device scaling in ultra-large-scale integrated circuitry (ULSI), the ultra-thin conventional gate oxide (SiO2) is unacceptable for many practical reasons. By replacing the SiO2 layer with a high dielectric constant material (high-k), many of the problems can be solved. In this study, a novel high-k dielectric thin film, i.e., TaOx doped with Zr, was deposited and studied. The films electrical, chemical, and structural properties were investigated experimentally. The Zr dopant concentration and the thermal treatment condition were studied with respect to gas composition, pressure, temperature, and annealing time. Interface layer formation and properties were studied with or without an inserted thin tantalum nitride (TaNx) layer. The gate electrode material influence on the dielectric properties was also investigated. Four types of gate materials, i.e., aluminum (Al), molybdenum (Mo), molybdenum nitride (MoN), and tungsten nitride (WN), were used in this study. The films were analyzed with ESCA, XRD, SIMS, and TEM. Films were made into MOS capacitors and characterized using I-V and C-V curves. Many promising results were obtained using this kind of high-k film. It is potentially applicable to future MOS devices

Incomprehension or resistance? : the Markan disciples and the narrative logic of Mark 4:1—8:30
No full textThe characterization of the Markan disciples has been and continues to be the object of much scholarly reflection and speculation. For many, the Markan author’s presentation of Jesus’ disciples holds a key, if not the key, to unlocking the purpose and function of the gospel as a whole. Commentators differ as to whether the Markan disciples ultimately serve a pedagogical or polemical function, yet they are generally agreed that the disciples in Mark come off rather badly, especially when compared to their literary counterparts in Matthew, Luke, and John.
This narrative-critical study considers the characterization of the Markan disciples within the Sea Crossing movement (Mark 4:1–8:30). While commentators have, on the whole, interpreted the disciples’ negative characterization in this movement in terms of lack of faith and/or incomprehension, neither of these, nor a combination of the two, fully accounts for the severity of language leveled against the disciples by the narrator (6:52) and Jesus (8:17–18). Taking as its starting point an argument by Jeffrey B. Gibson (1986) that the harshness of Jesus’ rebuke in Mark 8:14–21 is occasioned not by the disciples’ lack of faith or incomprehension but by their active resistance to his Gentile mission, this investigation uncovers additional examples of the disciples’ resistance to Gentile mission, offering a better account of their negative portrayal within the Sea Crossing movement and helping explain many of their other failures.
In short, this study argues that in Mark 4:1–8:26, the disciples are characterized as resistant to Jesus’ Gentile mission and to their participation in that mission, the chief consequence being that they are rendered incapable of recognizing Jesus’ vocational identity as Israel’s Messiah (Thesis A). This leads to a secondary thesis, namely, that in Mark 8:27–30, Peter’s recognition of Jesus’ messianic identity indicates that the disciples have finally come to accept Jesus’ Gentile mission and their participation in it (Thesis B).
“Chapter One: Introduction” offers a selective review of scholarly treatments of the Markan disciples, which shows that few scholars attribute resistance, let alone purposeful resistance, to the disciples.
“Chapter Two: The Rhetoric of Repetition” introduces the methodological tools, concepts, and perspectives employed in the study. It includes a section on narrative criticism, which focuses upon the story-as-discoursed and the implied author and reader, and a section on Construction Grammar, a branch of cognitive linguistics founded by Charles Fillmore and further developed by Paul Danove, which focuses upon semantic and narrative frames and case frame analysis.
“Chapter Three: The Sea Crossing Movement, Mark 4:1–8:30” addresses the question of Markan structure and argues that Mark 4:1–8:30 comprises a single, unified, narrative movement, whose action and plot is oriented to the Sea of Galilee and whose most distinctive feature is the network of sea crossings that transport Jesus and his disciples back and forth between Jewish and Gentile geopolitical spaces.
Following William Freedman, “Chapter Four: The Literary Motif” introduces two criteria (frequency and avoidability) for determining objectively what constitutes a literary motif and provides the methodological basis and starting point for the analyses performed in chapters five and six.
“Chapter Five: The Sea Crossing Motif” establishes and then carries out a lengthy narrative analysis of the Sea Crossing motif, which is oriented around Mark’s use of θάλασσα (thalassa) and πλοῖον (ploion), and “Chapter Six: The Loaves Motif” does the same for The Loaves motif, oriented around Mark’s use of ἄρτος (artos).
Finally, “Chapter Seven: The Narrative Logic of the Disciples (In)comprehension” draws together all narrative, linguistic, and exegetical insights of the previous chapters and offers a single coherent reading of the Sea Crossing movement that establishes Theses A and B.
