Abstract: A device includes: a complementary transistor including: a first transistor having a first source/drain region and a second source/drain region; and a second transistor stacked on the first transistor, and having a third source/drain region and a fourth source/drain region, the third source/drain region overlapping the first source/drain region, the fourth source/drain region overlapping the second source/drain region. The device further includes: a first source/drain contact electrically coupled to the third source/drain region; a second source/drain contact electrically coupled to the second source/drain region; a gate isolation structure adjacent the first and second transistors; and an interconnect structure electrically coupled to the first source/drain contact and the second source/drain contact.

Abstract: A joint for the prefabricated concrete blocks of the quake-resistant pier developed for connecting the prefabricated reinforced concrete blocks employed in the non-plastic hinge zone of the earthquake-resistant reinforced concrete pier comprises mainly an upper prefabricated reinforced concrete block and a lower prefabricated reinforced concrete block, wherein a layer of resin binder is applied between the engaging concave and the engaging convex of the prefabricated reinforced concrete blocks, so as to connect the two prefabricated reinforced concrete blocks to withstand shear stress applied on the pier, and the two prefabricated reinforced concrete blocks are also connected firmly by pre-stressed keys to withstand bending stress applied on the pier. By connecting mechanisms, the present way of prefabricated construction can achieve the same earthquake-resistant capability as the traditional in situ construction.

Abstract: A structural steel seismic-resistant beam-to-column connection is provided with a pair of rib plates installed symmetrically above and below the connection. The rib plates are perpendicularly to an upper and a lower beam flange and disposed at positions corresponding to the center of the beam web. The rib has a variable cross section at its front end and a relatively lower lengthened section at its rear end. Through the use of the rib plate, the stress concentration at those fan type weld access holes of the beam web as well as the junction of the full penetration weld between the beam flange and column flange can be alleviated, and the plastic hinge can be limited to the beam at a specified portion and can develop excellent plastic rotation capacity in the case of a severe earthquake.
