The modular mask can be used repeatedly to make multiple, substantially-similar modular dies. The modular die contains a substrate with an integrated circuit as well as a conductive layer containing a source metal and a gate metal connected respectively to the source and gate of the integrated circuit. The gate metal of the conductive layer is located only in an outer portion of the modular die. The modular die can be made by providing the integrated circuit in a first and second portion of the substrate, providing the conductive layer on both the first and second portions, making a first modular die by patterning the conductive layer on the first portion using the modular mask; moving the modular mask to the second portion and using it to make a second modular die by patterning the conductive layer on the second portion. Thus, fewer mask sets need to be made, improving efficiency and reducing costs.

  • Publication number: 20120146106
    Abstract: Apparatus for semiconductor device structures and related fabrication methods are provided. One method for fabricating a semiconductor device structure involves forming a layer of dielectric material overlying a doped region formed in a semiconductor substrate adjacent to a gate structure and forming a conductive contact in the layer of dielectric material. The conductive contact overlies and electrically connects to the doped region. The method continues by forming a second layer of dielectric material overlying the conductive contact, forming a voided region in the second layer overlying the conductive contact, forming a third layer of dielectric material overlying the voided region, and forming another voided region in the third layer overlying at least a portion of the voided region in the second layer. The method continues by forming a conductive material that fills both voided regions to contact the conductive contact.

    Abstract: In one embodiment, a method of forming a multi-die semiconductor device is provided. A plurality of dice is mounted on a semiconductor substrate, and neighboring ones of the dice are separated by a distance at which a first one of the neighboring dice will contact a meniscus of a flange of the neighboring die during underfill to form a capillary bridge between the neighboring dice. Solder bumps are reflowed to electrically connect contact terminals of the plurality of dice to contact terminals on a top surface of the substrate. Underfill is deposited along one or more edges of one or more of the plurality of dice. As a result of the capillary bridge formed between neighboring dice, flow of underfill is induced between the bottom surfaces of the neighboring dice and the top surface of the substrate. The dispensed underfill is cured.

    Abstract: The yield of a semiconductor device is improved. Inside the resin sealing body which forms a semiconductor device, the semiconductor chip is sealed in the state where it has arranged aslant to the upper and lower sides of a resin sealing body. In the suspension lead which supports the die pad carrying this semiconductor chip, the small recess is formed in the fifth surface of the opposite side with the surface on which the semiconductor chip was mounted. This recess is a portion used as the starting point when making die pad 2a slanting. The side surface of the side near a die pad between two side surfaces of this recess is formed in the state where it inclined rather than the side surface of the side near the periphery of a resin sealing body.
