Title: Inspecting method of pattern
Inventor: SAKOU YUTAKA
IPC: H01L21/66
Filed: 1982-05-07
Abstract: PURPOSE:To decide a critical degree of a defect appropriately by calculating distances up to picture elements at specific positions from the boundaries of the patterns about sample and standard patterns according to a specific rule and comparing them. CONSTITUTION:Distance converting value is shown as a position (i, j) in F(i, j) and the sample and standard patterns in f(i, j) and g(i, j) and these value and patterns are processed by a formula F1(i, j)=[F1(i, j-1)+f(i, j)].g(i, j) in the most fundamental case when the sample pattern extends in the longitudinal (i) direction and there is the defect in the orthogonal (j) direction. The patterns are scanned in the (i) direction, and a formula FK(i, j)=FK(i, j-1) is formed in a defect section of f=0 and g=1, but f=1 and g=1 and a formula FK(i, j)=FK(i, j-1)+1 are formed in a normal section, and a formula FK(i, j)=0 is formed when g=0 holds. Accordingly, the value of the lowermost sections of the patterns indicates pattern width by sequential propagation, and compared with a reference value, and the critical degree can be determined. A position to be compared j8 is obtained by a foromula D(i, j)=g(i, j).[1-g(i, j+1)] from the standard pattern (g). When width in the plural directions is measured independently and decided at every direction, the critical degrees can be determined about defects of every kind.

Abstract: PURPOSE:To enable the setting of sample tubes at random in a rotary table, by storing the time whereat the sample tubes are set in the rotary table, and by moving the sample tubes to a sampling position in the sequence wherein the tubes set earlier are moved earlier. CONSTITUTION:When a sample rack 4 holding sample tubes 5 is set at random in a time of stoppage of a rotary table 3, the time of the setting is stored in CPU 12 through a rack detecting sensor 11. When a driving element 2 is operated in this state, a control element 10 controls the driving element 2 so as to forward fast the table 3 so that the rack 4 set earliest be moved to a sampling position on the basis of the data stored in the CPU 12. The rack 4 which is moved to the sampling position and of which sampling is completed is moved to a position off the sampling position by an operation of forwarding fast a rack 4 set earliest secondly. Accordingly, it is possible to take the former rack 4 away from the table 4 at that position in the time of stoppage of the table and to set a rack 4 to be sampled subsequently in said vacant position.

Abstract: PURPOSE:To suppress the noise on a power supply line, and prevent the malfunction of an input buffer circuit, by a method wherein a structure possessing a multilayered conductive layer is employed for a package mounting an IC chip in which I/O buffer circuit power supply lines are separated. CONSTITUTION:The power supply line of output buffer circuits 11-1-11-N are supplied by a power supply line 14-V having power supply potential, and a power supply line 14-G having ground potential.

The power supply line in a chip 10 is supplied in the manner that said power supply line is separated into I/O buffer circuits respectively. Therefore, the voltage fluctuation generated on the power supply line connected with the output buffer circuit in a package 20 does not affect adversely upon the input buffer circuit. Further, by using a multilayer conductor wiring structure, inductance which the power supply line possesses can be remarkably reduced, so that the voltage fluctuation itself generated on the power supply line of the output buffer circuit in the package can be restricted within a small value.
