TL;DR: In this article, a method of fabricating a semiconductor device includes the steps of forming a wiring layer on the surface of a silicon substrate, depositing a silicone film on the whole surface of the semiconductor substrate including the wiring layer by a CVD method and exposing the silicone film to oxidative plasma with enhanced frequencies including components of 1 MHz or less to change to a silicon oxide film, the depositing step and exposing step being alternately repeated in the same apparatus till the silicon oxide material having any desired thickness is obtained.

The resulting silicon oxide film has the smooth surface and the high density.

TL;DR: In this article, the capability of 2.64 Tbit/s (132 ch/spl times/20 Gbps) WDM transmission over 120 km single mode fiber (SMF) is experimentally demonstrated.
Abstract: The capability of 2.64 Tbit/s (132 ch./spl times/20 Gbit/s) WDM transmission over 120 km single mode fibre (SMF) is experimentally demonstrated. High density WDM signal with 0.6 bit/s/Hz spectrum efficiency is produced by optical duobinary coding.

TL;DR: In this paper, a three-dimensional memory module includes a plurality of semiconductor device units, every adjacent two of which are stack-connected via through-holes by a bump connecting method.
Abstract: A three-dimensional memory module includes a plurality of semiconductor device units, every adjacent two of which are stack-connected via through-holes by a bump connecting method. Each of the plurality of semiconductor device units includes a carrier having a circuit pattern and the through-holes connected to the circuit pattern. The semiconductor device unit also includes at least one semiconductor memory chip mounted on the carrier such that the semiconductor memory chip is connected to the circuit pattern, and at least one chip select semiconductor chip mounted on the carrier to be connected to the circuit pattern such that the chip select semiconductor chip can select the semiconductor memory chip.

TL;DR: In this paper, a method of separating a wafer into individual die is disclosed, where a substrate with organic thin-film multiple layers is etched along a scribe line with excimer laser to form a groove to expose a portion of the substrate before sawing the substrate along the saw blade with a saw blade.
Abstract: A method of separating a wafer into individual die is disclosed. The wafer includes a substrate with organic thin-film multiple layers. A portion of the organic multiple layers is etched along a scribe line with excimer laser to form a groove to expose a portion of the substrate before sawing the substrate along the scribe line with a saw blade. Plasma etching or ion beam etching or sand blasting is an alternative to the excimer laser.

TL;DR: In this article, a character string input system includes an input storage portion for temporarily storing input character string with an incomplete input indicative signs, and a supplementing candidature storage portion temporarily stores candidate character strings for the incomplete word supplementing portion and the neglected word supplementING portion.
Abstract: A character string input system includes an input storage portion for temporarily storing input character string with an incomplete input indicative signs. There is also a word dictionary storing words. An incomplete word supplementing portion compares the character string with the word stored in the word dictionary. Also, there is a neglected word supplementing portion for predicting a word to be supplemented at the position of the incomplete input indicative sign representing an omitted word. A supplementing candidature storage portion temporarily stores candidate character strings for the incomplete word supplementing portion and the neglected word supplementing portion. A supplementing control portion controls the incomplete word supplementing portion and the neglected word supplementing portion on the basis of the incomplete input indicative sign, and retrieves the candidate character string corresponding to the position of the incomplete input indicative sign in the character string.
