Abstract: A stacked integrated circuit (IC) device and a method are disclosed. The stacked IC device includes a first semiconductor element. The first substrate includes a dielectric block in the first substrate; and a plurality of first conductive features formed in first inter-metal dielectric layers over the first substrate. The stacked IC device also includes a second semiconductor element bonded on the first semiconductor element. The second semiconductor element includes a second substrate and a plurality of second conductive features formed in second inter-metal dielectric layers over the second substrate. The stacked IC device also includes a conductive deep-interconnection-plug coupled between the first conductive features and the second conductive features. The conductive deep-interconnection-plug is isolated by dielectric block, the first inter-metal-dielectric layers and the second inter-metal-dielectric layers.

Abstract: The invention discloses a stereo-image display device. The stereo-image display device includes a light source, a polarization beam splitter, two image modulators and an image projection lens set. The light source is used for generating a parallel beam. The polarization beam splitter is used for splitting the parallel beam into two polarization orthogonal beams. Each image modulator is used for generating one visualized optical signal according to one of the beams and reflecting the visualized optical signal to the polarization beam splitter. Two visualized optical signals are to combine to one beam by the polarization beam splitter, and are projected through the image projection lens set onto a screen.

Abstract: A stereo-image display device is disclosed in the invention. The stereo-image display device includes a polarization beam splitter, an image projection lens set, a first image unit and a second image unit. The first image unit is used for generating a first visual optical signal to the polarization beam splitter. The second image unit is used for generating a second visual optical signal to the polarization beam splitter. A polarization direction of the second visual optical signal is orthogonal to a polarization direction of the first visual optical signal. Two visual optical signals are combined to one beam by the polarization beam splitter, and are projected through the image projection lens set onto a screen.
