Abstract: A method of fabricating a semiconductor device applies a LOCOS profile characteristic to an edge portion of an STI in a HV region to thereby lower compressive stress that is concentrated on the side of the STI. A field oxide film is formed so that only edge portions of HV region (active region II) may be in contact with a comparatively stiff STI, and then, a thick gate oxide film is formed on the HV region by utilizing a nitride film as a mask. After the nitride film as a mask is removed, a thin gate oxide film is formed on a LV region (an active region I in which a thin gate oxide film is formed). As a result, a thinning phenomenon of a gate oxide film at an edge portion of STI is prevented that otherwise would occur when the gate oxide film for HV grows in a normal STI structure by utilizing a nitride film as a mask.

Abstract: An underwater receptacle has a pressure balancing arrangement that balances he underwater force that tend to hold a receptacle and its mated plug together. The pressure balancing arrangement also relieves the air pressure formed between the insert discs of the plug and receptacle when connecting the insert discs respective electrical pins and sockets.

This forces the volume of air back into its original position and eliminates a vacuum suction by neutralizing the pressure on the plug when disconnecting the plug from the receptacle.
