A method of manufacturing a circuit substrate of the present invention, includes the steps of forming an n-layered (n is an integer of 1 or more) wiring layer connected electrically to a metal plate on the metal plate, forming an electroplating layer on a connection pad portion of an uppermost wiring layer of the n-layered wiring layer by an electroplating utilizing the metal plate and the wiring layer as a plating power-supply path, and removing the metal plate.

Method of manufacturing a circuit substrate and method of manufacturing an electronic parts packaging structure

A graphic processing system for accomplishing high-speed processing of data conversion processing by effectively utilizing file information of input graphic data to improve processing efficiency of data processing inside blocks, and by optimizing block division. This system includes a processing portion for dividing input graphic data in a block unit and executing conversion processing of the graphic data to mask production data, and a storage portion having an optimization condition file for storing the input data information, optimization information of the graphic data to be divided by the processing portion, processing result information, etc, capable of updating and registering the optimization information, and comprises the steps of executing graphic processing by utilizing file data when graphic data existing inside the block is approximate to the graphic data information registered to the optimization condition file; scanning the graphic data inside the block so as to judge whether or not the quantity of the graphic data inside the block exceeds a memory capacity in the processing portion for executing the conversion processing, and to judge the density and the property of the graphic data when the graphic data is not approximate to the graphic data information; and dividing the graphic data into optimum blocks so that the data quantity becomes the quantity that can be processed by the processing portion; and storing the divided information, the input graphic data information and the processing result information.

Parallel graphic processing system using a network

A plurality of data processing units each having a first controller for computing design data assigned in advance so as to generate graphic data and a first storage device for receiving transfer of the design data and storing the design data temporarily, and a second controller, for when a data storage allowable value of the first storage device which has received transfer of the design data is exceeded, recognizing a data excess flag rising on that occasion, and transferring excessive data in the design data assigned to the one data processing unit to another data processing unit, thereby controlling computation share among data processing units. The design data are converted in parallel into graphic data while monitoring is performed of the data processing units. By adopting such a structure, it is no longer required to increase the number of fields for reassigning design data more than necessary, and it is possible to achieve high-speed processing of parallel data, such as mask data, of the LSI within the capacity of the field memory given to the data processing units.

Data processor and method of processing data in parallel
