SiC TO SiC WAFER BONDING

MRS Proceedings, 2002
ABSTRACTSiC wafers with an RMS roughness of 1.5 nm were bonded in a dedicated ultrahigh vacuum bonding chamber. Successful fusion of wafers was observed at temperatures as low as 800°C under a uniaxial mechanical stress of 20 MPa. Cross-section transmission electron microscopy (XTEM) of a specimen bonded at 1100°C revealed parts of the interface where ...

Radioluminescence characterization of SiC and SiC/SiC for 1.8MeV electron irradiation

Journal of Nuclear Materials, 2013
Abstract As a first step to permit in situ monitoring of radiation induced degradation in SiC materials, characterization by means of 1.8 MeV electron induced radioluminescence (RL) was performed. RL has been measured at 75 Gy/s and 5.4 kGy/s and temperatures from 15 to 450 °C (288–723 K), to total doses ⩽200 MGy for hot pressed, reaction bonded ...

Low dose irradiation performance of SiC interphase SiC/SiC composites

Journal of Nuclear Materials, 1998
Abstract Reduced oxygen Hi–Nicalon™ fiber reinforced composite SiC materials were densified with a chemically vapor infiltrated (CVI) silicon carbide (SiC) matrix and interphases of either `porous' SiC or multilayer SiC and irradiated to a neutron fluence of 1.1×1025 n m−2 (E>0.1 MeV) in the temperature range of 260 to 1060°C.

2019
Background Lupus erythematosus (LE) is an autoimmune disease that can have negative repercussions on the quality of life (QL) of those who suffer from it. The QL can be influenced by socio-demographic factors are related to the disease itself. Aims To analyse the associative power of socio-demographic (age and sex) and medical variables (type of lupus,

Chemical Vapor Infiltrated SiC/SiC Composites (CVI SiC/SiC)

2005
CVI SiC/SiC composites are manufactured via Chemical Vapor Infiltration Process. The SiC-based matrices are deposited from gaseous reactants on to a heated substrate of SiC fiber preforms. An interphase coated on the fibers allows control of damage and mechanical behavior.

The effect of SiC nanowires on the flexural properties of CVI-SiC/SiC composites

Journal of Nuclear Materials, 2007
Single crystal SiC nanowires with volume fractions of 0%, 1.6%, 5.7% and 6.1% were incorporated in the matrices of several CVI-Tyranno-SA/SiC composites, to study the effects of the nanowires on the flexural properties of the composites. The results show that the SiC nanowires are very effective reinforcements for SiC/SiC composites.

Comparison of 3C–SiC, 6H–SiC and 4H–SiC MESFETs performances

Materials Science in Semiconductor Processing, 2000
Abstract A comparative analysis of the main DC and microwave performances of MESFETs made of the commercially available silicon carbide polytypes 3C–SiC, 6H–SiC and 4H–SiC is presented. In this purpose, we have developed an analytical model that takes into account the basic material properties such as field dependent mobility, critical electric field,
