Title: Method for forming thin filmtransistor
Inventor: HU GUO-REN
IPC: H01L29/786
Filed: 2002-05-23
Granted: 2003-06-21
Abstract: A method for forming a thin film transistor (TFT) is disclosed. The invention uses metal electroless plating or chemical displacement processes to form metal clusters adjacent the sidewall of amorphous silicon active region pattern so as to crystallize the amorphous silicon amid the subsequently performed metal induced lateral crystallization (MILC) process. The amorphous silicon is crystallized to form polysilicon having parallel grains. Since the amorphous silicon will crystallize with a specific angle which is measured between the grain orientation and the side wall of the amorphous silicon, a tilt channel connecting the source and drain region of the TFT is utilized to upgrade the electron mobility across the tilt channel, wherein the grain orientation of polysilicon in the tilt channel perpendicular to a gate electrode which is subsequently formed above the tilt channel.

Title: Method and apparatus for a clock circuit
Inventor: MOSHE DAVID
IPC: G06F1/10
Filed: 2002-05-24
Granted: 2003-12-21
Abstract: An additional clock is delayed from a master clock by 90 degrees to provide needed additional clock edges during a cycle. The need for the additional clock edges arises from the desire to perform a read and a write in the same clock cycle. The precise delay is achieved through a clock programmable delay that can be updated as the frequency of the master clock may change. The amount of delay is conveniently detected by using two other programmable delays to achieve a 180 degree delay. The 180 degree delay is easily detected using a flip-flop. The programming signal that caused the total of 180 degrees of delay caused 90 degrees per programmable delay. The same programming signal is then coupled to the clock programmable delay to achieve the desired 90 degrees of delay for the additional clock.

Title: Image display device and display driving method
Inventor: WASHIO HAJIME
IPC: G02F1/133
Filed: 2002-09-16
Granted: 2003-10-21
Abstract: A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.

Abstract: An optical system of an optical disk recording apparatus irradiates a disk with a main beam for use in writing a data signal onto a disk and a sub-beam succeeding the main beam. When writing a data signal onto the disk, a site on the disk at which a data signal is written by the main beam is subsequently irradiated with the succeeding sub-beam. Light of the succeeding sub-beam reflected from the disk is received by a succeeding light receiving sub-region. A sampling circuit samples a signal at periods when the emission power of the main beam is at the recording level, among output signals from the succeeding light receiving sub-region. Based on the sampled signal at the recording level, a beta value detection circuit and a jitter amount detection circuit obtain a beta value and a jitter amount indicative of the recording state of the data signal recorded on the disk, respectively.
