found to dominate the opticalloss in the 1.5–1.6 μm range in high index GeSiON-based planarwaveguides deposited by plasma-enhanced chemical vapor deposition using hydrogen-based precursors. The fundamental N–H bond-related absorption and its double frequency overtone were measured to be ∼560 cm−1 and 1.8 cm−1, respectively, resulting in their ratio of 310±10. The opticalloss, extracted from analysis

This work addresses the preparation of ultrathin (effective oxide thickness, 42 A) interpoly-oxynitride (SiO x N y ) films by annealing thin nitride films with high density N2Oplasma and N2O rapid thermal annealing. The proposed oxynitride dielectrics formed using N2Oplasmaannealing exhibited low gate leakage current, high breakdown electric field, long ten-year lifetime, and large effective
这项工作致力于通过使用高密度 N 2 O 等离子体和 N 2 O 快速热退火对薄氮化物薄膜进行退火来制备超薄(有效氧化物厚度,42 A)多氧氮化物 (SiO x N y ) 薄膜。所提出的使用 N 2 O 等离子体退火形成的氧氮化物电介质表现出低栅极漏电流、高击穿电场、长十年寿命和大有效势垒高度。这些优异的性能可归因于聚-II/氮化物界面中掺入的高浓度氧以及聚氧氮化物间膜的陷阱密度的降低。电介质是电可擦除可编程只读存储器的多氧化层间的合适替代品。

High quality electroncyclotronresonanceplasma‐enhancedchemicalvapordeposition SiO2 film and annealing are investigated in an effort to enhanceSiO2/GaAsinterfaceproperties. Dramatic reduction of interface state density is achieved by reducing nitrogen and hydrogen impurities in the SiO2 film and optimizing the annealing temperature. A minimum interface state density of 3×1010 eV−1 cm−2 is obtained

presence of crystalline Si nanoparticles. Photoluminescence (PL) spectra taken from irradiated areas showed two distinct peaks around 570 and 800nm. From a combined TEM, Rutherford back scattering (RBS), forming gas annealing (FGA), PL, and PL lifetime study it is concluded that the 570nm peak with a short PL lifetime (<10ns) is related to defects characteristic of silicon suboxides and that the 800nm

Siliconoxynitridefilms were deposited using a plasma-enhancedchemicalvapordeposition process. The bond configurations of the constituent atoms in the deposited film were analyzed using x-ray photoelectron spectroscopy. Analysis of the Si 2p spectra showed the presence of nonstoichiometric silicon oxide and siliconoxynitride. Analysis of the binding energy shifts induced by Si–O and Si–N bond
