  • Publication number: 20250062274
    Abstract: A bonding apparatus with a bonding head having vacuum channels and switchable channels, and the method of forming the same are provided. The bonding apparatus may include a vacuum pump, a blower, a controller communicatively coupled to the vacuum pump and the blower, and a bonding head. The bonding head may include a main body, a first vacuum channel in the main body, wherein the first vacuum channel is connected to the vacuum pump, and a first switchable channel in the main body, wherein the first switchable channel is connected to the vacuum pump and the blower.

  • Publication number: 20250054786
    Abstract: A die bonding tool includes a bond head having a moveable component. The moveable component may be moveable between an extended position in which a lower surface of the moveable component protrudes below a lower surface of the bond head and a retracted position in which the lower surface of the moveable component does not protrude below the lower surface of the bond head. The moveable component may be used to control a shape of a semiconductor die secured to the lower surface of the bond head during a process of bonding the semiconductor die to a substrate. Accordingly, void areas and other bonding defects may be avoided and the bond formed between the semiconductor die and the target substrate may be improved.

  • Patent number: 7067975
    Abstract: A full color display panel with a mirror function comprises an organic light-emitting area, a spectrum-modulation layer, a color-separating layer, a transparent substrate and a semi-reflecting layer. The organic light-emitting area includes a plurality of pixels for emitting white light. The spectrum-modulation layer is doped with a fluorescent material and/or a phosphorescent material in a transparent protecting medium. The color-separating layer includes a light-shielding frame and a plurality of color filters. The light-shielding frame is disposed around the peripheral of the color filters. The transparent substrate has a first surface and a second surface opposite to the first surface. The color-separating layer is disposed above the first surface of the transparent substrate. The spectrum-modulation layer is disposed above the color-separating layer. The organic light-emitting area is disposed above the spectrum-modulation layer.
