Abstract: A connector assembly comprises a body and an elastic terminal position assurance (TPA) member. The body includes a plurality of contacts and defines a coupling groove exposing some of the plurality of contacts. The TPA member includes a hinge portion and a latch, and is adapted to indicate whether the plurality of contacts are sitting at designated positions. The hinge portion is hinged with respect to the body on one end of the TPA member. The latch is formed such that the other end of the TPA member engages with the coupling groove.

Abstract: A connector assembly includes a cap housing in which a first terminal is disposed, a plug in which a second terminal is disposed, and a terminal position assurance (TPA) member. The plug has a first end portion and a second end portion opposite the first end portion. The second end portion is inserted into the cap housing. A first end portion of the cap housing and the first end portion of the plug to which a wire is connected are each a coupling target. The TPA member is disposed at the coupling target. The TPA member includes a first block and a second block partitioned from one another in a circumferential direction of the wire.

Abstract: A method of manufacturing a flash memory device includes the steps of sequentially forming a tunnel oxide film and a first polysilicon layer on a semiconductor substrate in which a device separation film is formed and then patterning the tunnel oxide film and the first polysilicon layer to form a floating gate; forming a mask so that a portion in which a source region will be formed can be exposed and then removing the device separation film at the exposed portion; forming a dielectric film including a lower oxide film, a nitride film, and an upper oxide film on the entire structure; performing an annealing process; then forming a second polysilicon layer on the dielectric film; sequentially removing the polysilicon layer, the upper oxide film, and the nitride film in a portion in which a source region and a drain region will be formed, and injecting impurity ions into the semiconductor substrate at a portion in which the lower oxide film remains to form a source region and a drain region; after removing the

Abstract: There is disclosed a method of manufacturing a flash memory device. In order to solve the problems that a break down voltage between wells is reduced and an insulating characteristic between the wells is lowered due to degraded barrier characteristic between the wells, in a flash memory device employing a triple well structure, the present invention forms an anti-diffusion region for preventing diffusion of dopants between a P-well region and a N-well region by nitrogen ion implantation, thus improving the electrical characteristic of the device.

Abstract: There is disclosed a method of manufacturing a flash memory device. In order to solve the problem that the coupling ratio of a gate electrode is low in a stack gate-type flash memory device, the present invention allows a control gate to surround a control gate from its to its bottom. Therefore, the present invention can increase the contact area of the floating gate and the control gate and can also increase the coupling ratio of the gate electrode.
