Abstract: A method of fabricating a silicon-on-insulator (SOI) substrate including an ultra-thin top Si-containing layer and at least one patterned buried semi-insulating or insulating region having well defined edges is provided. The method includes a step of implanting first ions into a surface of a Si-containing substrate so as to form a first implant region of the first ions in the Si-containing substrate. Following the implantation of first ions, a first annealing step is performed which forms a buried semi-insulating or insulating region within the Si-containing substrate. Next, second ions that are insoluble in the semi-insulating or insulating region are selectively implanted into portions of the buried semi-insulating or insulating region. After the selective implant step, a second annealing step is performed which recrystallizes the buried semi-insulating or insulating region that includes second ions to the same crystal structure as the original Si-containing substrate.

An electronic device is described incorporating a substrate; and a plurality of thin films laminated on the substrate and part of the thin films are formed on a predetermined circuit pattern, wherein a transfer film for repairing a defect is fitted into a recess where the low layers of the thin films are exposed by removing part of a single or multi-layer thin films covering a defective portion included on the thin films and its surrounding portion.

Abstract: The object of the present invention is to reduce the number of inputs to LCD driver chips, and to suppress the occurrence of variances between the chips. A ten bit wide binary counter 202 is self activated in synchronization with a system clock. Each of multiple five-step shift registers 200 having ten bit widths stores gamma compensation data received from a PC. Each of multiple comparators 204 compares a binary counter value (X) with a value (Y) stored in a ten bit wide five-step shift register 200, and converts the gamma compensation data into a pulse width. The output of each comparator 204 is latched by each of multiple D-FFs 206 in synchronization with the system clock, and each of multiple time/voltage converters 208 passes the output of a D-FF 206 through an LPF and generates a reference gamma compensation voltage.

Abstract: A liquid crystal (LC) lightvalve comprising a twisted nematic LC layer whose molecules are aligned with pixel edges at the mirror backplane, thereby providing improved contrast and efficiency, and reduced visibility of post spacers in black state. The present invention is directed to an LC structure wherein the backplane is rubbed in a direction rectilinear with pixel edges. The LC layer is given the same twist rotation and birefringence as in the conventional TN lightvalve. Polarization control is maintained by illuminating the lightvalve with light whose polarization is rotated by the twist angle relative to the x,y, pixel axes, and by collecting the orthogonally polarized component of the reflected light. The lightvalve top glass is thus rubbed in a direction which is rotated by the twist angle from the horizontal or vertical direction at which the backplane is rubbed.

An inspection method for an array substrate is constituted, in which a quantity of charges stored in the storage capacitor becomes C (Vd1−Vcs1) by supplying simultaneously a pulse signal Vd and a pulse signal Vcs to the storage capacitor from a signal line and a Cs line on a TFT array substrate, and an influence of the disconnection of the Cs line is taken into consideration when the above-described quantity of charges is detected in a reading circuit. Note that the above-described inspection is performed not for all the storage capacitors, but for one storage capacitor in each Cs line. Thus, the inspection for all the Cs lines in liquid crystal panels from 14 inch diagonal to 18 inch diagonal is terminated in about 1 to 2 seconds.
