  • Publication number: 20030042620
    Abstract: A method for forming printed re-routing for wafer level packaging, especially chip size packaging. The method includes forming a contact layer on a semiconductor die, forming a conductive redistribution structure on the contact layer, and etching the contact layer of the die by using the conductive redistribution structure as a self-aligning mask. The present method significantly decreases the complexity and costs for generating redistribution structures in wafer level packaging by discarding expensive processes for photolithography and plating. Furthermore, using the redistribution structures as a self-aligning mask improves alignment and reduces the number of processes required, leading to greater production optimization and efficiency.

  • Publication number: 20030026159
    Abstract: Circuitry using fuse and anti-fuse latches (62) for selecting the number of input/output channels (98, 109) after encapsulation is disclosed. The various embodiments allow conventional bond pads (14, 16, 18) to be used for initial selection of the number of input/output channels prior to encapsulation. However, by providing different selection signals (52, 54), the number of input/output channels may be changed by the user at any time after encapsulation. Other embodiments employ “enable” latch circuits (133,135) allow the initial selection by the users at any time after encapsulation, and then at least one more subsequent selection.

  • Patent number: 5963315
    Abstract: The present disclosure is a method for in situ monitoring of backside contamination on a semiconductor wafer (120) between processing steps which are performed in a multi-chamber tool (500). In a first form, a laser source (220) and a detector (210) are mounted on a robotic arm (110, 111), or within a semiconductor processing tool (500). The laser (220) and detector (210) move along with the robotic arm (110) as the robotic arm (110) shuffles the wafer (120) between processing carriers (610-650) and chambers (510-540). While in transit the backside of the semiconductor wafer (120) is scanned by a laser beam (221), whereby contamination is detected by a detector (210). The laser (220) and detector (210) then scan the backside of the wafer (120) while the robotic arm (110) is in transit and/or while the robotic arm (110) is stationary in the processing sequence.

  • Patent number: 5578841
    Abstract: A multiple output, vertical MOSFET device (11) with improved electrical performance and thermal dissipation is integrated with an additional semiconductor device or semiconductor circuit (18) on a single semiconductor substrate (34). The method of making the vertical MOSFET device (11) involves thinning the semiconductor substrate (34) after fabricating the vertical MOSFET device (11) and the semiconductor circuit (18) to reduce the vertical component of electrical and thermal resistance and to increase the thermal dissipation efficiency. Electrical performance is improved by thinning the semiconductor substrate (34) and by providing a low resistivity, patterned metal buried layer. Thermal management is enhanced by using flip chip bumps (24) to dissipate heat from a top surface (31) of the semiconductor substrate (34) and by using the patterned buried metal layer (26) to dissipate heat from a bottom surface (32) of the semiconductor substrate (34).

  • Patent number: 5455194
    Abstract: A method for the fabrication of a trench isolation region (44) includes the deposition of first, second, and third oxidizable layers (28, 34, 42). The first oxidizable layer (28) is deposited to overlie the surface of a trench (12) formed in a semiconductor substrate (10). The first oxidizable layer (28) also fills a recess (26) formed in a masking layer (14), and resides adjacent to the upper surface of the trench (12). After oxidizing the first oxidizable layer (28), a second oxidizable layer (34) is deposited to fill the trench (12). A third oxidizable layer (42) is deposited to overlie the second oxidizable layer (34) and fills a remaining portion of the recess (26). An oxidation process is performed to oxidize oxidizable layer (42) and a portion of second oxidizable layer (34) to form a trench isolation region (44). In an alternative embodiment of the invention, a shallow isolation region (46) is formed in proximity to the trench isolation region ( 44).
