IPC: H01L23/522
Filed: 1993-01-04
Abstract: PURPOSE: To provide a new low-RC multi-level interconnected structure for silicon technology by providing steps, such as a step for etching a first dielectric material layer and a step for arranging a pattern-formed metallic layer and repeating the steps a predetermined number of times. CONSTITUTION: This method comprises a step 'a' of etching a first dielectric material layer 6 according to a pattern of a plurality of islands within one plane, and a step 'b' of surrounding the islands with a second dielectric material, and a step 'c' of arranging a metal layer 12, which has been pattern- formed, adjacent to the first dielectric material 6. The steps 'a' to 'c' are repeated a predetermined number of times, while the pattern of the first dielectric material 6 is changed for the subsequent layers. Next, the first dielectric material 6 is etching-removed. Thus, the multi-level metallization structure is formed on an integrated circuit formed on a substrate 4. By this interconnection technology, the electric loss for the entire chip can be reduced with considerable high efficiency.

Abstract: PURPOSE:To easily form a sharp wobbling pit, by constituting the driving circuit of an acoustic and optical modulator by using the eta/4 phase distributor of a high frequency signal, a frequency converter, and a zero phase synthesizer. CONSTITUTION:The frequencies F1 and F2 of oscillators 1 and 2 are converted to signals (k) and (l), and (m) and (n) having the lead and lug of the phase of eta/4, and furthermore, an output (f) whose frequency is either (F1+F2) or (F1-F2) can be obtained by the frequency converters 3-1 and 3-2 and the zero phase synthesizer 9.

Abstract: PURPOSE: To resolve a probability that an arbitrarily short clock pulse occurs in clock switching by preventing the occurrence of a pulse length shorter than the pulse length of an old clock source when switching it to a new clock source by a clock switcher circuit. CONSTITUTION: In a DFA means 31, an input clock switching signal 32 is compared with a DFA means output 34 by an exclusive NOR gate 36. If the clock used by a circuit doesn't coincide with a clock whose use is required, an inequality signal 38 is generated. The signal 38 is transferred to a gate 40 to generate a change request indication 42. A gate means 60 converts the indication 42 to output it to an FF means 80. The means 80 generates proper FF means output signals 86 and 88. Thereafter, the signal 86 is given to a MUX means 100. The output of the means 100 is a timing slave output signal 108, and it functions as a DFA check input signal 110 also. The signal 110 functions as an input to the means 31, and the signal 32 is compared with the signal 110 to complete a loop.
