Title: Manufacture of semiconductor device
Inventor: CHISHIMA KENJI
IPC: H01L21/78
Filed: 1992-07-24
Abstract: PURPOSE:To protect a wiring layer from peeling-off starting from a gap between a semiconductor chip and an alignment mark and provide a highly reliable semiconductor device. CONSTITUTION:When an Al film 16 which is a wiring layer is patterned, the Al film 16 is left not only on the wiring and pad pattern parts but also on the whole surface of a gap 14 between a semiconductor chip 13 and an alignment mark 15 in a scribe line 12. Further, when an overcoat film 21 is patterned so as to expose pads, the overcoat film 21 is left on the whole surface of the gap 14. With this constitution, the Al film 16 is protected from peeling-off starting from the gap 14 and the scattering and adhesion of the peeled Al film 16 onto the semiconductor chip 13 can be avoided.

Title: Adaptive notch filter
Inventor: MAEDA YOSHIO
IPC: H04N9/68
Filed: 1989-08-24
Abstract: PURPOSE:To eliminate the crosstalk component of an edge part without lowering resolution by detecting an edge component included in an image from an input ted luminance signal, and increasing/decreasing the attenuation quantity of a bond blocking filter corresponding to the quantity of detected signal components. CONSTITUTION:Sampling values inputted to coefficient circuits 15-17 are shown as three points S1, S3, and S5 arranging in a vertical direction. Therefore, the output of the band blocking filter 3 goes to S3+(k/4) (S1-2S3+S5). It is pro vided with band blocking characteristic centering a vertical frequency 525/4(c/ph), and the attenuation quantity is increased as making a multiplication coefficient (k) approach to 1. Meanwhile, the correlation energy DYH and DYV of the image in horizontal and vertical directions are outputted from an edge detection circuit 4. A ROM table 34 decides the value of the multiplication coefficient (k) from the values DYV and DYH, and when the value DYV is small and the value DYH is large, the coefficient (k) is made approached to 1, and it is decreased when it is not. Therefore, the crosstalk component can be elimi nated as keeping the resolution of the luminance signal.
