Publication number: 20030153135Abstract: A fabrication method for forming a semiconductor device having a fuse is provided. A substrate includes a cell array area, a peripheral circuit area and a global step difference between the cell array area and the peripheral circuit area. The substrate comprises a fuse formed in the peripheral circuit of the substrate. An interlayer insulating layer is formed on the global step difference. The global step difference is reduced by a cell open process. A multilevel metal interconnection including an intermetal insulating layer is formed on the resultant structure. During the cell open process and/or the process for forming the multilevel metal interconnection, the interlayer insulating layer and/or the intermetal insulating layer is partially removed to form a recess. A passivation layer is formed on the multilevel metal interconnection. A fuse opening is formed through the recess to expose the fuse.Type: ApplicationFiled: October 29, 2002Publication date: August 14, 2003Applicant: Samsung ElectronicsInventors: Min-Sang Kim, Dong-Won Shin

Publication number: 20030153136Abstract: The invention relates to improvements in a method of manufacturing a semiconductor device in which deterioration in a transistor characteristic is avoided by preventing a channel stop implantation layer from being formed in an active region. After patterning a nitride film (22), the thickness of an SOI layer 3 is measured (S2) and, by using the result of measurement, etching conditions (etching time and the like) for SOI layer 3 are determined (S3). To measure the thickness of SOI layer 3, it is sufficient to use spectroscopic ellipsometry which irradiates the surface of a substance with linearly polarized light and observes elliptically polarized light reflected by the surface of a substance. The etching condition determined is used and a trench TR2 is formed by using patterned nitride film 22 as an etching mask (S4).Type: ApplicationFiled: August 12, 2002Publication date: August 14, 2003Applicant: MITSUBISHI DENKI KABUSHIKI KAISHAInventors: Takuji Matsumoto, Mikio Tsujiuchi, Toshiaki Iwamatsu, Shigenobu Maeda, Yuuichi Hirano, Shigeto Maegawa

Publication number: 20030153137Abstract: This invention concerns a process of forming a polarizable layer in a buried oxide layer of a silicon-on-insulator substrate for the fabrication of non-volatile memory. This process comprises implanting, through the active silicon layer, Si ions into the buried oxide layer at an ion implantation energy selected so that the implanted ion has its peak concentration between 5-50 nm from the silicon/buried oxide interface. The implantation step can occur while externally heating the silicon-on-insulator substrate at a temperature between 25-300 degrees Celsius. After implantation, an annealing step may be completed to repair any damage the implantation may have created in the silicon-on-insulator substrate.Type: ApplicationFiled: March 5, 2003Publication date: August 14, 2003Inventors: Harold L. Hughes, Patrick J. McMarr, Reed K. Lawrence

Publication number: 20030153140Abstract: Offsets and timing skews in data signals captured in a data receiver are reduced by adaptively adjusting a transition threshold of the data receiver. A data corrector provides a set of adjustment vectors for adjusting the transition threshold of the data receiver. The data corrector uses differential clock signals and a reference voltage to generate the set of adjustment vectors to be provided to the data receivers. The data receiver is an improved receiver incorporating a trip point adjustor that receives the set of adjustment vectors from the data corrector to adjust its trip point relative to the reference voltage.Type: ApplicationFiled: February 13, 2002Publication date: August 14, 2003Applicant: Micron Technology, Inc.Inventor: Brent Keeth
