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 multi-functional massage device has an accommodating body, an actuating element located above the accommodating body, and a casing. A vibration motor is arranged in the accommodating body. A conductive column electrically connected to one electrode of the vibration motor is formed on a top of the accommodating body. The actuating element has a collar, a cap, a ring, and a conductive spring. One open end of the collar receives the cap. A ring is formed at a lower portion of the actuating element. A conductive spring is mounted between the column and the ring. The casing receives the accommodating body, the ring, the conductive spring, and a battery that is electrically connected to another electrode of the motor. The protrusion, the top of the conductive spring, and the conductive column are aligned with one another. The battery is further electrically connected to the casing.

Abstract: An advertise effect photo pen includes a front tube, a connecting seat and a rear tube. The rear end of the front tube is installed with an outer thread, in assembling, the outer thread is screwed into an inner thread of the connecting tube. The rear end of the connecting seat is installed with an outer thread, in assembling, the rear end of the connecting seat is screwed into an inner thread of the rear tube. Therefore, the rear tube is connected to the front tube by the connecting seat. The front tube is a hollow transparent material and a refill is connected at a front end. The surface of the connecting seat is a hollow transparent material. After processed by web printing, the surface is formed with a transparent surface and a shielding surface; and the shielding surface or the transparent surface has advertise patterns. The light emitting unit is a single color or a multiple color element.
