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

Worker morphology of the ant Gnamptogenys striatula Mayr (Formicidae, Ectatomminae) in different landscapes from the Atlantic Forest domain

Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms.Ants have been used to evaluate the relationship between the environment and species coexistence and morphology.In the present Stickers study, we analyzed the morphology of workers of Gnamptogenys striatula Mayr in different
