Title: Timing generating circuit for semiconductor integrated circuit device
Inventor: KONDO HARUFUSA
IPC: H03K19/00
Filed: 1986-12-01
Abstract: PURPOSE:To prevent the influence of the fluctuation, etc., of a manufacturing process from being received by providing an enable signal output means including a circuit equivalent to a critical path for a signal generating means and have the delay of a prescribed time to an input clock signal and providing a control means to give the signal of a signal generating means to an object circuit only at the time of outputting the enable signal. CONSTITUTION:The circuit is composed of an address signal generating source (PLA) 2, a delaying circuit part 31 and a control circuit part 32. A programmable logic array PLA2 is synchronized and operated to a clock input terminal 3a and a clock phi1 and the output signal is used as the address of a memory 4. The memory 4 is constituted so that the action can be completed until a clock phi2 is given to a resetting input terminal 3b. With the clock phi1, an RS flip-flop 32a of a control circuit 32 is set, and therefore, the delaying circuit 31 also starts an action with the clock phi. Thus, a delaying time td only is delayed from the clock phi1 and the output of the delaying circuit 31 is displayed at an output terminal 3e. By obtaining the AND of the output of the RS flip-flop 32 and the output of the delaying circuit 31, the enable signal of the suitable timing is displayed at an output terminal 3c. For this reason, for example, even when the performance of the transistor is deteriorated, the output of the delaying circuit 31 is also delayed only for the part in which the action speed of the signal generating source 2 is delayed by it and an optimum timing is obtained.

Inventor: KASHIMA HISATO
IPC: H05K1/09
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To securely execute conduction without generating a space between a conductor for via hole and a conductor for wiring. SOLUTION: A through-hole which becomes a via hole is provided for a green sheet, constituted of a ceramic material such as glass ceramic. The through-hole is filled with conductive material for via hole, which is constituted of Pd having a high content in Ag and Pd.

Thus, the conductor for via hole turns into a state where it protrudes from the surface of the ceramic substrate especially by about 20-40μm after burning.  Since the amount ratio of Pd is high and the projection of the conductor for via hole is sufficient, conduction between the conductor for via hole and the conductor for wiring, which is provided for the necessary part of the surface of the ceramic substrate and which is mainly composed of Au, is executed securely, and a highly reliable ceramic circuit substrate can be obtained.
