Publication number: 20140349447Abstract: To stably remove a resin body formed in a supply route of a resin in a sealing step. A leadframe has, in a sub-runner portion thereof, a sub-through-hole. The sub-through-hole has, along a first direction along which the sub-runner portion extends, a first portion located on the side of a main-runner portion and a second portion located on the side of a gate portion relative to the first portion. In a plan view, an opening width of the sub-through-hole in the first direction is greater than that of the sub-through-hole in a second direction perpendicular to the first direction. In a plan view, an opening width of the sub-through-hole in the second direction gradually decreases from the first portion to an end portion of the second portion on the side of the gate portion.Type: ApplicationFiled: May 20, 2014Publication date: November 27, 2014Applicant: Renesas Electronics CorporationInventors: Hiroshi Fujii, Shigeki Tanaka, Kazuaki Yoshida

Publication number: 20080096475Abstract: The present invention aims to improve the polishing rate during the polishing process of semiconductor substrates, hard disk substrates or the like by using a polishing composition containing silica particles, water, a basic substance and an inorganic salt, and by a polishing method using such a polishing composition. This polishing composition can be produced by mixing silica particles, water, a basic substance and an inorganic salt, and it is also obtained by adding an inorganic salt into a conventionally known alkaline polishing composition containing silica particles. As the inorganic salt, there is used an alkali metal salt or an ammonium salt such as KCl, K2SO4, KNO3, NaCl, Na2SO4, NaNO3, NH4Cl, NH4NO3, and (NH4)2S04. A polishing composition, wherein silica particles do not agglomerate when an inorganic salt is added, can improve the polishing rate significantly.Type: ApplicationFiled: March 3, 2005Publication date: April 24, 2008Inventor: Kazuaki Yoshida

Publication number: 20050201375Abstract: An uninterruptible transfer can be realized during a line failure in a transmission system performing a packet transmission between transmitting apparatuses connected via a plurality of lines. In a method for realizing the uninterruptible transfer, test packets including information of the number of packets received from the transmitting apparatus of a destination are periodically sent to the transmitting apparatus of a source. The transmitting apparatus of the source compares the received information of the number of packets included in the received test packets with the number of packets sent out to the transmitting apparatus of the destination via one line. When the comparison shows a disagreement between the number of the received packets and the number of the sent-out packets, packets corresponding to the disagreement are resent to the transmitting apparatus of the destination via another line.Type: ApplicationFiled: May 5, 2005Publication date: September 15, 2005Inventors: Yoshihide Komatsu, Hirofumi Yagawa, Kazuya Ryu, Kazuaki Yoshida, Toshinobu Tsunematsu
