Patent number: 8891098Abstract: Page-group data indicating many pages is analyzed to acquire the degree of reuse of page components as an analysis result. A set of page data pieces in the page-group data is acquired as a data block, the number of the pieces corresponding to a unit page number that is the number of pages to be processed collectively as a single task when a conversion processor in a system actually converts the page-group data into drawing data. A predetermined conversion processor converts the data block into drawing data to acquire a conversion processing time. A predicted value of a conversion processing time required for the conversion processor in the system to actually convert the page-group data is accurately obtained using the conversion processing time of the data block. An operator is notified of the analysis result and the predicted value and can easily ascertain the appropriateness of the page-group data.Type: GrantFiled: September 25, 2013Date of Patent: November 18, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8891948Abstract: A photodiode excellent in responsivity receives flashes of light emitted from flash lamps in the process of heating a semiconductor wafer by irradiation with flashes of light, and the waveform of the intensity of the flashes of light versus time is acquired using voltage data obtained from an output from the photodiode. Then, a temperature calculating part performs a heat conduction simulation using the acquired data to calculate the temperature of the semiconductor wafer irradiated with the flashes of light from the flash lamps. The temperature of the semiconductor wafer is computed using data corresponding to the intensity of the flashes of light obtained from the output from the photodiode. This allows the determination of the surface temperature of the semiconductor wafer irradiated with the flashes of light, irrespective of the waveform of the emission intensity of the flash lamps.Type: GrantFiled: May 17, 2011Date of Patent: November 18, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8861944Abstract: In light-irradiation heating with a total irradiation time of one second or less, two-stage irradiation is performed, including a first stage of light irradiation of a semiconductor wafer, which irradiation produces an output waveform that reaches a peak at a given emission output; and a second stage of supplemental light irradiation of the semiconductor wafer, which irradiation is started after the peak, producing an emission output smaller than the above given emission output. The emission output in the second stage is two thirds or less than the above given emission output at the peak. The first-stage light-irradiation time is between 0.1 and 10 milliseconds, and the second-stage light-irradiation time is 5 milliseconds or more. This allows the temperature of the semiconductor wafer even at a somewhat greater depth below the surface to be raised to some extent while allowing the surface temperature to be maintained at a generally constant processing temperature.Type: GrantFiled: October 22, 2012Date of Patent: October 14, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8857944Abstract: Web paper is transported by roll with two or more drive rollers. The two adjacent drive rollers each have difference in rotation speed in accordance with a draw ratio. Accordingly, tension is applied to the web paper. Tension of the web paper between the adjacent drive rollers is detected by a tension sensor. A tension controller controls the detected tension value so as to be a target tension value. A predictive control device predicts decrease in tension during an initial printing period where tension control is not stable, and increases rotation speeds of the drive rollers downstream of a print unit to suppress the decrease in tension. Consequently, tension acting on the web paper is appropriately controlled also during the initial printing period, resulting in possible reduction in printing quality.Type: GrantFiled: March 28, 2013Date of Patent: October 14, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8859443Abstract: The first flash irradiation is performed on a semiconductor wafer preheated to 500° C. to heat a front surface of the semiconductor wafer. Thereafter, the second flash irradiation is performed to reheat the front surface of the semiconductor wafer before the temperature of the front surface of the semiconductor wafer becomes equal to the temperature of a back surface of the semiconductor wafer. Thus, the second flash irradiation is performed before the temperature of the front surface of the semiconductor wafer falls. Even if less energy is consumable by the second flash irradiation, the efficiency of heating of the front surface of the semiconductor wafer resulting from each iteration of the flash irradiation is improved.Type: GrantFiled: February 6, 2012Date of Patent: October 14, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8852966Abstract: A semiconductor wafer, on the surface of which a silicon dioxide base material and an amorphous silicon thin film are formed in this order, is carried into a chamber. An insulated gate bipolar transistor (IGBT) is connected with a power supply circuit to a flash lamp, and the IGBT makes an energization period to the flash lamp to be 0.01 millisecond or more and 1 millisecond or less, consequently making a flash light irradiation time to be 0.01 millisecond or more and 1 millisecond or less. Since a flash heat treatment is performed with a remarkably short flash light irradiation time, the excessive heating of the thin film of amorphous silicon is suppressed and harmful influence such as the exfoliation of the film is prevented.Type: GrantFiled: September 11, 2012Date of Patent: October 7, 2014Assignee: Dainippon Screen Mfg.

Patent number: 8848253Abstract: A threshold matrix generation part determines a turn-on order in a matrix area where a threshold matrix is generated and determines a threshold value of each matrix element. In determining the turn-on order, a temporary evaluation value element is obtained based on a distance between each undetermined matrix element whose position in the turn-on order has not been determined and each determined matrix element. If these matrix elements are located in the same position with respect to a row or column direction, the temporary evaluation value element is corrected such that the undetermined matrix element is less evaluated based on the evaluation value. Then, the position of an undetermined matrix element that is most highly evaluated in the turn-on order is determined. Accordingly, a threshold matrix that suppresses the occurrence of a grid-like dot pattern can be provided.Type: GrantFiled: March 28, 2013Date of Patent: September 30, 2014Assignee: Dainippon Screen Mfg.
