摘要:
An LTCC module includes an LTCC substrate and a pad part formed on an undersurface of the LTCC substrate for mounting the LTCC substrate to an external substrate. The pad part includes a metal pad layer formed on an undersurface of the LTCC substrate and a solder layer formed on an undersurface of the metal pad layer.

A semiconductor chip package includes a main board; a ceramic substrate having a cavity within which at least one chip is electrically mounted, the cavity being placed at a lower portion of the ceramic substrate facing the main board; and a conductive shielding layer provided with a predetermined thickness on the outside of the ceramic substrate. The ceramic substrate includes: at least one first ground line electrically connecting the conductive shielding layer with the main board; at least one second ground line electrically connecting the conductive shielding layer with the chip; and at least one signal line electrically connecting the chip with the main board. Thus, manufacturing costs are lowered because of the reduced number of components being used, miniaturization in device design can be achieved because of the small volume of the package, and the ground performance can be improved.

In a semiconductor chip, a body has a top surface where a pattern is formed, an underside surface opposing the top surface and a plurality of side surfaces. A plurality of electrode pads are formed on the top surface of the body to connect to an external terminal. A shielding conductive film is formed on the surfaces excluding the top surface of the body where the pattern is formed. A conductive via is extended through the body to connect one of the electrode pads with the conductive film.

Provided is an electron chip module having a heat sink that can increase heat dissipation efficiency. A bottom surface of a module circuit board and an upper surface of a heat sink are in direct contact with each other by using a metal wire, such that heat generated during the operation of a heat-generating device chip mounted onto the module circuit board can be effectively dissipated to the outside.

An oxygen generator including: a humidifier tank moves up and down according to a horizontal movement of an adjustment knob so that the humidifier tank can be readily detachable, and thus a user can securely and conveniently use the oxygen generator without any water leakage from the humidifier tank during an operation of the oxygen generator. Also, it is possible to reduce noise due to driving of a compressor, noise due to the nitrogen exhaustion, and noise due to driving of a fan portion when the oxygen generator operates, to display purity information about the discharged oxygen, sensed by an oxygen sensor, as a digitalized numerical value on a display portion so that a user may readily recognize a current oxygen purity, and to drive the compressor at a low power consumption based on a discharge flow rate of oxygen and thereby reduce the power consumption.
