Cu/SiO2 hybrid bonding with planarized dielectric and isolated metal connections can realize ultradense interconnects (e.g., ≤1 μm) by eliminating the microbumps underfill through direct of Cu–Cu SiO2–SiO2. However, low-temperature (oxide-free surface) SiO2–SiO2 (hydroxylated is difficult to be compatible in a mechanism. We circumvent this contradiction constructing co-hydroxylated functional surface on platform. By combining optimizing protocol Ar/O2 plasma activation formic acid solution...

The optical properties of four kinds lubricating greases (urea, lithium, extreme pressure molybdenum disulfide lithium greases) with different NLGL (National Lubricant Grease Institute America) numbers were investigated using terahertz time-domain spectroscopy. Greases grades have unique spectral features in the range. Comparison experimental data predictions based on Lorentz—Lorenz theory exhibited that refractive indices each kind grease dependent their consistency. In addition, (MoS2) as...
The quantitative analysis of zinc isopropyl-isooctyl-dithiophosphate (T204) mixed with lube base oil from Korea viscosity index 70 (T204-Korea70) is presented by using terahertz time-domain spectroscopy (THz-TDS). Compared the middle-infrared spectra n-butyl-isooctyl-dithiophosphate (T202) and T204, THz T202 T204 show weak broad absorption bands.
