Abstract: There is provided an integrated circuit device having an input/output electrostatic discharge (I/O ESD) protection cell. The integrated circuit device includes an I/O ESD protection cell comprising a VDD ESD protection element connected between an I/O pad and a VDD line, a ground voltage (VSS) ESD protection element connected between the I/O pad and a VSS line, and a power clamp element connected between the VDD line and the VSS line, and wherein the VDD ESD protection element, the power clamp element, and the VSS ESD protection element in the I/O ESD protection cell are adjacent to each other so they can be connected in a straight line or are arranged to partially overlap.

Abstract: The present invention disclosed herein is a Vertical Double-Diffused Metal Oxide Semiconductor (VDMOS) device incorporating a reverse diode. This device includes a plurality of source regions isolated from a drain region. A source region in close proximity to the drain region is a first diffusion structure in which a heavily doped diffusion layer of a second conductivity type is formed in a body region of a second conductivity type. Another source region is a second diffusion structure in which a heavily doped diffusion layer of a first conductivity type and a heavily doped diffusion layer of the second conductivity type are formed in the body region of the second conductivity type. An impurity diffusion structure of the source region in close proximity to the drain region is changed to be operated as a diode, thereby forming a strong current path to ESD (Electro-Static Discharge) or EOS (Electrical Over Stress). As a result, it is possible to prevent the device from being broken down.

Abstract: A scroll compressor includes a stationary scroll and an orbit scroll for circulating refrigerant. Lubricant is introduced into the refrigerant at an inlet side of the compressor to maintain a seal between the scrolls. Lubricant is separated from the refrigerant within a discharge chamber. A control mechanism varies the flow of lubricant into the refrigerant as a function of a pressure occurring at an outlet side of the scrolls, and also as a function of the amount of lubricant present in the discharge chamber.
