Publication number: 20100279471Abstract: A system for dispensing an underfill material between an integrated circuit (IC) chip and a substrate includes a platform at which the underfill material is supplied. The IC chip and the substrate are mounted at the periphery of the platform. The platform rotates and facilitates the movement of the underfill material toward the IC chip and the substrate. The system further includes a Bernoulli tube that is located proximate to the IC chip and the substrate. The Bernoulli tube generates a low pressure in the proximity of the IC packages. The low pressure facilitates the dispensing of the underfill material between the IC chip and the substrate.Type: ApplicationFiled: July 16, 2009Publication date: November 4, 2010Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: Vittal Raja MANIKAM, Yit Meng LEE, Vemal Raja MANIKAM

Patent number: 7823534Abstract: A developer nozzle is moved from a periphery of a wafer toward the central portion while an exposed substrate held at a spin chuck is being rotated about a vertical axis and while a developing solution is being discharged from the developer nozzle, and this way the developing solution is supplied to the surface of the wafer, the developer nozzle having a slit-like ejection port whose longitudinal direction is oriented to the direction perpendicular to the radial direction of the wafer. The movement speed of the nozzle is higher than a case where a nozzle with a small-diameter circular nozzle is used, and this enables a development time to be reduced. Further, the thickness of a developing solution on a substrate can be reduced, so that the developing solution can be saved.Type: GrantFiled: December 24, 2004Date of Patent: November 2, 2010Assignee: Tokyo Electron LimitedInventors: Atsushi Ookouchi, Taro Yamamoto, Hirofumi Takeguchi, Hideharu Kyouda, Kousuke Yoshihara

Patent number: 7819080Abstract: A substrate transfer system to reduce total processing time by transferring a substrate at a first delivery stage to a process block where processing can be carried out earliest. The substrate processing apparatus includes a first transfer device delivering a wafer with respect to a substrate carrier, and a second transfer device delivering a wafer between a plurality of process blocks and the first transfer device via a first delivery stage, to transfer the wafer with respect to the process blocks. The process block where there is no wafer or where processing of the last wafer within the relevant process block will be completed earliest is determined based on processing information of the wafers from the process blocks, and the wafer of the first delivery stage is transferred by the second transfer device to the relevant process block. This ensures smooth transfer of the wafer to the process block.Type: GrantFiled: November 11, 2004Date of Patent: October 26, 2010Assignee: Tokyo Electron LimitedInventors: Nobuaki Matsuoka, Yoshio Kimura, Akira Miyata

Patent number: 7820243Abstract: A resist coating method supplies a resist solution to substantially the center of a target substrate to be processed while rotating the target substrate at a first rotational speed, then decelerates the rotation of the substrate to a second rotational speed lower than the first rotational speed, or until rotational halt, makes the deceleration smaller in the deceleration step as the rotational speed becomes closer to the second rotational speed or the rotational halt, and accelerates the rotation of the substrate to a third rotational speed higher than the second rotational speed to spin off a residue of the resist solution.Type: GrantFiled: October 16, 2006Date of Patent: October 26, 2010Assignee: Tokyo Electron LimitedInventors: Kousuke Yoshihara, Tomohiro Iseki
