Abstract: PURPOSE:To prevent intrusion of impurities into connecting holes easily, in addition to the prevention of overetching of the connecting holes at thin film sections of insulating films along with obtaining good covering, by removing the lower parts of the resist mask holes of an insulating film by etching whose side component in the lateral direction is not zero. CONSTITUTION:An insulating film 13 to be flattened by heat treatment is laminated on an etching stopper insulating film 12. After heat treatment, the lower part of the resist mask holes 20 of the insulating film 13 are removed by etching whose side component in the lateral direction is not zero, using a resist mask 15. In addition, the etching stopper insulating film 12 is removed by anisotropic etching using that resist mask 15, and connecting holes are made in the insulating films 12, 13. For example, isotropic wet etching is performed using the resist mask 15, and the lower parts of the resist mask holes 20 of the BPSG film 13 having been flattened are removed into a tapering shape. Next anisotropic dry etching is performed using the same resist mask 15, and connecting holes are completed by removing the Si3N4 film 12 and an HLD film 11.

Abstract: PROBLEM TO BE SOLVED: To optimally arrange respective blocks etc., in a short processing time by calculating the change of a wiring delay caused by virtually moving a selected block in a predetermined direction, comparing it with a predetermined inter-block delay limitation, and determining and displaying the moving direction of the selected block. SOLUTION: When a function block is specified as an object to be moved, a virtual movement control part 110 for the function block as the object to be moved carries out a virtual movement in two directions, i.e., horizontal and vertical axis directions. At that time, a net delay value calculating part 108 calculates the delay value due to a connected net based on LSI logic connection information 112. A moving direction indicating control part 109 indicates the moving direction whose delay value satisfies the condition given by inter- function-block delay limitation information 115. According to this construction, the movement direction satisfying the delay value limitation is indicated at the time when the function block which is desired to be moved is indicated so that the movement in the optimum movement direction can be realized without repeating trial and error.
