Disclosed is a caster control apparatus for a suspension of a vehicle. When the vehicle travels on a road which causes a vehicle body to lean to one side, the caster of a lowered wheel is increased, and the caster of a raised wheel is decreased, such that the casters of the wheels on both sides are offset with each other. Therefore, the vehicle is inhibited from leaning due to the lateral slope of the road, and the straight-line stability of the vehicle can be reliably maintained.

A wafer level package may include a semiconductor substrate supporting an electrode pad. A first insulating layer may be provided on the semiconductor substrate. The first insulating layer may include a first opening through which the electrode pad may be exposed. A seed metal layer may be provided on an entire surface of the first insulating layer. A redistribution interconnection metal layer may be provided on the seed metal layer. A second insulating layer may be provided on the redistribution interconnection metal layer. The second insulating layer may have a second opening spaced from the first opening to expose a portion of the redistribution interconnection metal layer. The second insulating layer may surround the redistribution interconnection metal layer. An unwanted portion of seed metal layer may be removed using the second insulating layer as an etch mask.

Disclosed is an LCD device for performing bi-directional display. The LCD device includes first and second display units, and a light supplying unit. The first display unit includes an LCD panel and a transflective film that is disposed under the LCD panel and has layers in which first and second layers having different refractivity indexes are alternately stacked. The transflective film partially reflects and transmits light incident onto the film. The light supplying unit is disposed between the first and second display units, and provide the first and second display units with light generated from a lamp by dividing the light, to thereby regulate a contrast ratio of a luminance between the first and second display units. Therefore, the structure of an LCD panel for performing bi-directional image display can be simplified, and the light loss in the transmission mode can be reduced.

In a stacked chip configuration, and manufacturing methods thereof, the gap between a lower chip and an upper chip is filled completely using a relatively simple process that eliminates voids between the lower and upper chips and the cracking and delamination problems associated with voids. The present invention is applicable to both chip-level bonding and wafer-level bonding approaches. A photosensitive polymer layer is applied to a first chip, or wafer, prior to stacking the chips or stacking the wafers. The photosensitive polymer layer is partially cured, so that the photosensitive polymer layer is made to be structurally stable, while retaining its adhesive properties. The second chip, or wafer, is stacked, aligned, and bonded to the first chip, or wafer, and the photosensitive polymer layer is then cured to fully bond the first and second chips, or wafers. In this manner, adhesion between chips/wafers is greatly improved, while providing complete fill of the gap. In addition, mechanical reliability is improved and CTE mismatch is reduced, alleviating the problems associated with warping, cracking and delamination, and leading to an improvement in device yield and device reliability.

In an LCD apparatus (400) having simplified structure and improved luminance, a light supplying unit (100) supplies an LCD panel (280) with red light during a time corresponding to one-third of a frame, green light during the time and blue light during the time. A light reflective-transmissive unit is disposed between the light supplying unit (100) and the LCD panel assembly (200) to transmit the red light, the green light and the blue light and to reflect an external light from exterior of the LCD panel assembly (200). The LCD apparatus displays an image by means of white light as well as red light, green light and blue light, thereby improving luminance and simplifying structure.

The present invention relates to a method for fabricating semiconductor capacitors, which enables the capacitance of the capacitors to be increased. This method comprises the steps of: forming a cylinder type polycrystalline silicon pattern on a semiconductor substrate; forming an amorphous metal film on the substrate in such a manner that the amorphous metal film covers the polycrystalline silicon pattern; crystallizing the amorphous metal film so as to form grown metal grains and grain boundaries between the metal grains; firstly etching the crystallized metal film by a wet etching process in such a manner that the polycrystalline silicon pattern is selectively exposed due to the difference in the wet etching rate between the metal grains and the grain boundaries; secondly etching the exposed portion of the polycrystalline silicon pattern by a wet etching process so as to form a storage node electrode whose surface has hemispherical grooves; and successively forming a dielectric layer and a plate electrode on the resulting structure in such a manner that they cover the storage node electrode.
