摘要:
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. The absolute particle count and differential/incremental particulate counts are calculated on a chamber-by-chamber, and wafer-by-wafer basis, using a data processor (230).

A wafer test assembly includes multiple probe head substrates arranged like tiles with connectors attached to one side and probes supported on the opposing side. In one embodiment, flexible cable connectors directly connect the connectors on the probe head tile to a test head, while in another embodiment the flexible cables connect the probe head tile to a PCB providing horizontal routing to test head connectors. In one embodiment, leveling pins provide a simplified support structure connecting to a retaining element attached to the tiles to provide for applying a push-pull leveling force. A test head connector interface frame enables rearrangement of connectors between the test head and the probe card to provide for both full wafer contact or partial wafer contact. The test head connectors are rearranged by being slidable on rails, or pluggable and unpluggable enabling movement over a range of positions.

The present invention provides a method of connecting an integrated circuit to a substrate and a corresponding circuit arrangement. Connecting occurs by performing the steps of: providing a main area (HF1) of the integrated circuit (1), which has an electrical contacting region (2), with a mechanical supporting structure (3a, 3b; 33a, 33b, 33c; 43a, 43b, 43c); providing a solderable surface region (5a, 5b; 35a, 35b, 35c; 60a, 60b, 60c) of the mechanical supporting structure (3a, 3b; 33a, 33b, 33c; 43a, 43b, 43c); providing a solderable terminal region (10; 5, 30; 40, 50), which is electrically connected to the electrical contacting region (2), on the main area (HF1) of the integrated circuit (1); providing a main area (HF2) of the substrate (20) with a first soldering region (22′, 23′; 22′, 23′, 22″, 23″), which can be aligned with the solderable surface regions (5a, 5b; 35a, 35b, 35c; 60a, 60b, 60c), and with a second soldering region (22, 23), which can be aligned with the solderable terminal region (10; 5, 30; 40, 50); and simultaneous soldering of the surface regions (5a, 5b; 35a, 35b, 35c; 60a, 60b, 60c) to the first soldering region (22′, 23′; 22′, 23′, 22″, 23″) and of the terminal region (10; 5, 30; 40, 50) to the second soldering region (22, 23).
摘要:
An electronic component has a plurality of chips which are stacked one above the other and contact-connected to one another. To form this component, a first planar chip arrangement is provided with the functional chips spaced apart from one another in a grid and with a filling material in the spaces between the chips to form an insulating holding frame that fixes the chips, the frame has chip-dedicated contact-connecting elements that serve for the electrical contact-connection to another chip of another chip arrangement and each chip has dedicated electrically conductive strips. At least one additional planar chip arrangement is formed by the same method as the first planar chip arrangement and is then stacked on the first planar chip arrangement so that the two chip arrangements lie one above the other and the respective contact-connecting elements of the two chip arrangements are connected to one another for electrical chip-to-chip contact-connection. Subsequently, each of the components, which comprise a stack of chips, is separated from the assembled stack of chip arrangements.

A semiconductor wafer contact system includes a sealed bladder (32) containing incompressible material. The sealed bladder (32) presses against a flexible circuit layer (28) including an array of electrical contacts (30). The bladder (32) forces the array of electrical contacts (30) against a corresponding array of device electrical contacts (12) on die (11) of a semiconductor wafer (10). The bladder (32) adapts in shape to compensate for die level and wafer level irregularities in contact height and non-parallelism. Additionally, bladder (32) ensures a constant force between membrane contacts (30) and die contacts (12), across the entire wafer (10).

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).
摘要:
A method of fabricating multiple trench semiconductor structures wherein a preferred embodiment includes forming an epitaxial silicon layer on a silicon substrate and a dielectric layer on the epitaxial silicon layer. An opening is then formed which extends through the dielectric layer and into the epitaxial silicon layer. Sidewall spacers are formed in the opening and an oxide lens is formed in the opening between the sidewall spacers. The sidewall spacers are then removed and trenches are formed in the opening where the sidewall spacers were formerly disposed.
