SELF-ASSEMBLY OF CHIP-SIZE COMPONENTS WITH CAVITY STRUCTURES: HIGH-PRECISION ALIGNMENT AND DIRECT BONDING WITHOUT THERMAL COMPRESSION FOR HETERO INTEGRATION

New surface mounting and packaging technologies, using self-assembly with chips having cavity structures, were investigated for three-dimensional (3D) and hetero integration of complementary metal-oxide semiconductors (CMOS) and microelectromechanical systems (MEMS).By the surface tension of small droplets of 0.5 wt% hydrogen fluoride (HF) aqueous

In recent years, data mining technology has been widely used in different fields.For petroleum industry, the application of data mining method not only can analyze the data faster and more accurately but also can reduce the defects such as misjudgment and missed judgment caused by relying on artificial monitoring.Fracturing is one of the key techni

BackgroundThe association between baseline seropositivity to human adenovirus (HAdV) type 5 and increased HIV acquisition in the Step HIV Vaccine Study has raised questions concerning frequency of acquired and/or persistent Adenovirus infections among adults at high risk of HIV-1 infection.MethodologyTo evaluate the frequency and pattern of HAdV sh
