Publication number: 20080179599Abstract: A salicide process is conducted to a thin film integrated circuit without worrying about damages to a glass substrate, and thus, high-speed operation of a circuit can be achieved. A base metal film, an oxide and a base insulating film are formed over a glass substrate. A TFT having a sidewall is formed over the base insulating film, and a metal film is formed to cover the TFT. Annealing is conducted by RTA or the like at such a temperature that does not cause shrinkage of the substrate, and a high-resistant metal silicide layer is formed in source and drain regions. After removing an unreacted metal film, laser irradiation is conducted for the second annealing; therefore a silicide reaction proceeds and the high-resistant metal silicide layer becomes a low-resistant metal silicide layer.Type: ApplicationFiled: October 22, 2007Publication date: July 31, 2008Applicant: Semiconductor Energy Laboratory Co., Ltd.Inventors: Tetsuji YAMAGUCHI, Atsuo Isobe, Satoru Saito

Publication number: 20060281318Abstract: Since sodium contained in glass, or glass itself has low heat resistance; a CPU fabricated using a TFT formed over a glass substrate or the like has not been obtained. In the case of operating a CPU with high-speed, the length of a gate (gate length) of a TFT is required to be shorter. However, since a glass substrate has large deflection, a gate electrode cannot have been etched to have a gate length short enough to be used for a CPU. According to the invention, a conductive film is formed over a crystalline semiconductor film formed over a glass substrate, a mask is formed over the conductive film, and the conductive film is etched by using the mask; thus, a thin film transistor with a gate length of 1.0 ?m or less is formed. In particular, the crystalline semiconductor film is formed by crystallizing an amorphous semiconductor film formed over a glass substrate by laser irradiation.Type: ApplicationFiled: August 24, 2006Publication date: December 14, 2006Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Atsuo Isobe, Satoru Saito, Saishi Fujikawa

Publication number: 20060091398Abstract: It is an object of the present invention to manufacture a TFT having a small-sized LDD region in a process with a few processing step and to manufacture TFTs each having a structure depending on each circuit separately. According to the present invention, a gate electrode is a multilayer, and a hat-shaped gate electrode is formed by having the longer gate length of a lower-layer gate electrode than that of an upper-layer gate electrode. At this time, only the upper-layer gate electrode is etched by using a resist recess width to form the hat-shaped gate electrode. Accordingly, an LDD region can be formed also in a fine TFT; thus, TFTs having a structure depending on each circuit can be manufactured separately.Type: ApplicationFiled: October 24, 2005Publication date: May 4, 2006Applicant: Semiconductor Energy Laboratory Co., Ltd.Inventors: Mayumi Yamaguchi, Atsuo Isobe, Satoru Saito

Publication number: 20050046743Abstract: An interlace image signal for four fields stored in an image memory is read out on a line-by-line basis and stored in an IP conversion data buffer. An output signal is a progressive image signal whose one horizontal period is twice that of an interlace image signal which is an input signal. Accordingly, reading of data from the IP conversion data buffer is made to correspond to one horizontal period on the output side at the time of outputting, and the signal which is read out is subjected to IP conversion and written into an output data buffer. By reading data from the output data buffer while data is being written into the output data buffer, the capacity of the output data buffer can be reduced to that corresponding to two horizontal lines.Type: ApplicationFiled: September 2, 2004Publication date: March 3, 2005Inventor: Satoru Saito

Publication number: 20050046742Abstract: A background color data output determination section outputs a control signal for selecting background color data until a predetermined number of vertical synchronization signals is counted after the start of IP conversion. Based on the control signal supplied from the background color data output determination section, a buffer data/background color data selection section selects a background color for output, so that the background color is output and displayed on the screen when a progressive image signal based only on an input image signal is not prepared at the time of actuation of power source, for example.Type: ApplicationFiled: September 2, 2004Publication date: March 3, 2005Inventor: Satoru Saito

Patent number: 6626652Abstract: A motor-driven compressor includes a motor and a compression portion for compressing a refrigerant. The motor-driven compressor comprises an input terminal for the motor and a drive circuit for controlling a rotation speed of the motor. The input terminal of the motor passes through an opening formed through a wall of a refrigerant suction route, whereby the input terminal is secured to the wall, and extends beyond the wall. The drive circuit controls the rotation speed of the motor and has an output connector. The output connector of the drive circuit is connected directly to the input terminal to secure the drive circuit to the wall. The direct connection eliminates a need for a wire connection between the output connector and the input terminal. Moreover, methods of assembling motor-driven compressors are disclosed.Type: GrantFiled: March 22, 2002Date of Patent: September 30, 2003Assignee: Sanden CorporationInventors: Shigeyuki Koyama, Satoru Saito
