Title: Processing method for evaluating semiconductor device
Inventor: KONOGI HIDEKAZU
IPC: H01L21/66
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To delayer a semiconductor device with a good controllability by removing insulating films formed on distributing wires by wet etching, exposing an upper wiring layer, causing a substance having an adhesive property on one plane to adhere to the surface of the upper wiring layer, and peeling off the adhesive substance after that. SOLUTION: Along with removing a silicon dioxide II of the uppermost layer and exposing an upper wiring layer 12, by performing etching for a specified time with an about 1-10% buffer solution of hydrofluoric acid, a silicon dioxide 13 on a lower wiring layer 14 is removed. Next, the adhesive surface of an adhesive substance 10 having an adhesive plane is caused to adhere to the surface of the wiring layer 12. By peeling off the adhesive substance 10 following that, the wiring layer 12 is peeled off simultaneously. And it becomes possible to expose the lower wiring layer 14, and delayering of the upper layer is completed. Consequently, it becomes possible to perform processing of exposing the lower wiring layer efficiently. As the result, it is possible to increase the efficiency of analysis of defective spots by delayering.

IPC: H04L12/42
Filed: 1988-08-18
Abstract: PURPOSE:To easily execute the transmission control of priority data without providing a timer in each station by preventing non-priority data from being transmitted when the length of transmission allowing data in a token frame is not more than a constant value when the non-priority data are transmitted for the respective stations. CONSTITUTION:An item F3 of the transmission allowing data length is provided in a token frame F to express a transmission right and when the non-priority data are transmitted, when the transmission allowing data length F3 is not more than the constant value, the transmission is not executed by the respective stations.

Filed: 1987-08-19
Abstract: PURPOSE:To reduce the capacitance between a gate electrode and a drain area, by forming a first opening between the side edges of adjacent first diffusion areas, and by forming a second opening over the central part of a second diffusion area. CONSTITUTION:A first opening 9 is formed in a square shape between the side edges of adjacent first diffusion areas 3. And, the opening 9 may be approximately throughout the space between adjacent second diffusion areas 7, or either may or may not overlap with the second diffusion areas 7. Therefore, the insulating film between a source electrode 10 and a drain area 11 can be very thick in that position to reduce the capacitance therebetween. Moreover, a second opening 8 is so formed in a gate electrode 5 over the second diffusion area 7 which becomes unnecessary as to reduce further the capacitance between the source electrode 10 and the second diffusion area 7. As a result, the parasitic capacity can be reduced effectively, thereby the device can operate at a high speed.

Filed: 1988-08-19
Abstract: PURPOSE:To evade the deterioration in the S/N0 caused due to overloaded quantizer with respect to an input signal with a large fluctuation by using an adaptive quantizer for a conventional differential coding system. CONSTITUTION:When an input signal Xj at a time (j) is inputted to a DPCM (differential coding system coder from an input terminal 1, a subtractor 2 calculates a prediction error signal Ej of a predicted value Xpj of an input signal and the input signal Xj and the result is inputted to a quantizer 3 as the prediction error signal Ej. An inverse quantizer 5 uses a quantized step widthDELTA to reproduce a prediction error signal Eqj of L-bit from an output code nj and outputted to an adder 6, where the output Xpj of the prediction device 7 is added to recover a decoding signal Yj. Thus, in the case of the comparison of the Xj signal coded by the same bit, an error caused by the quantizer 3 from the Eqj signal because of the small dynamic range than that of the Xj signal and coding with high accuracy is attained.

Abstract: PURPOSE:To sufficiently reduce the lead angle after molding by forming both male sides and the female end obliquely to reduce the dimensional irregularity irrespective of the thickness of a plate. CONSTITUTION:Both sides of a male die 29 for guiding when leads 27 are bent are oblique surfaces 32 inclining in the bending direction of the leads. The end of longitudinally movable female die 33 is projected at the top toward the die 29 from the bottom to form an oblique surface 37 to collide with the oblique surface 32.

Then, when moved down while the sides are pressed, the leads 27 are further inclined to the sealer side. Then, when the dies 29, 30 are separated from the pad 20, the leads 27 are deformed in a direction separating from the sealer 24 to become 0 deg. of bending angle, i.e., vertical state. According to this construction, the dimensional irregularity is reduced irrespective of the thickness of a lead frame plate, and the leads are not damaged.
