摘要:
A method of forming a top gate thin film transistor (TFT). By performing photolithography using a first reticle, a photoresist layer having a thick photoresist layer portion and a thin photoresist layer portion is formed on a silicon layer in an active area. Thus, a channel layer and source/drain regions in a silicon island are defined by the same patterning process. In addition, a gate and an LDD region in the silicon island are defined by photolithography using a second reticle and a backside exposure process. Accordingly, the top gate TFT fabrication process of the present invention requires only two reticles, and thereby reduces costs.

A method of forming a color filter on a substrate having pixel driving elements. A substrate having a plurality of light-transmitting areas and active areas is provided. A pixel driving element is formed on the substrate in each active area, wherein an insulation layer is formed between each pixel driving element. A planarization layer is formed on the pixel driving elements and the insulation layer. Part of the planarization layer is removed to form contact holes and openings, wherein the contact holes expose part of the pixel driving elements, and the openings expose the insulation layer in the light-transmitting areas. Color pigment is filled into the openings to form a color filter on the substrate having the pixel driving elements. Transparent pixel electrodes are formed in the contact holes to electrically connect the pixel driving elements, wherein the transparent electrodes extend onto part of the color filter.

A transflective LCD device having various cell gaps. The transflective LCD device is characterized by the passivation layer being formed on a lower substrate in a reflective region. A color filter layer is formed above the passivation layer, wherein a first thickness of the color filter layer in the reflective region is smaller than a second thickness of the color filter layer in a transmissive region. A transparent organic element is formed on an inner side of an upper substrate in the reflective region for bridging a gap in a liquid crystal layer between upper and lower substrates, wherein one end of the transparent organic element shores up the lower substrate. Thus, the gap thickness in the reflective region is smaller than that in the transmissive region.

A method of fabricating a polysilicon thin film transistor with a self-aligned lightly doped drain (LDD) is described. At first a polysilicon-island region and a gate insulating layer are subsequently formed on a glass substrate performed by a pre-treatment. Then a metal layer and a cap layer are subsequently formed on the gate insulating layer. The cap layer and the metal layer are defined to form a gate. A heavily doped region is formed in the polysilicon island region with serving the gate as a mask. An activation step is performed on the heavily doped region and a sidewall of the metal layer. The cap layer above the metal layer and the sidewall of the metal layer performed by the activation step are removed. A lightly doped region is formed in the polysilicon-island region with serving the remaining metal layer.

摘要:
An under bump metallurgy (UBM) structure formed over a bond pad and for use in conjunction with a solder ball, provides an upper copper layer over a subjacent composite film that includes a nickel film over a further copper film over a titanium film. One or more reflow operations are used to form a molten solder ball and conditions are selected to ensure that all of the copper from the upper copper layer is dissolved within the molten solder. For SnAg leadfree solder, this leads to the formation of SnAgCu-like leadfree solder. The resulting interface between the solder ball and the nickel layer includes regularly spaced Cu6Sn5 nodules as intermetallics but is free of Ni3Sn4 which can spall into the molten solder causing reliability problems.
