Title: Method for embedding interlayer connecting hole
Inventor: KONDO HIDEKAZU
IPC: H01L21/768
Filed: 1993-12-14
Abstract: PURPOSE:To deposite aluminum only from the bottom part of an interlayer connecting hole with excellent selectivity by removing the natural oxide film at the exposed surface of a metal wiring, a decomposition layer, contaminant and the like with chlorine by plasma etching, and forming the polymerization film, which is formed by the reaction of carbon and hydrogen in the plasma, only on the inner surface of the interlayer connecting hole. CONSTITUTION:A natural oxide film 2a at the bottom surface of a via-hole 3a is removed by plasma etching, and the surface side of a silicon oxide layer 3 is also removed. Thus, a decomposition layer 3b and contaminant 4 are removed. This is because chlorine has the purification action. A plasma polymerization film 5 is formed on the inner surface of the via-hole 3a by this plasma etching. That is to say, carbon and hydrogen react in the plasma, and the plasma polymerization film 5 that is the organic polymerization film is formed. The polymerization film 5 is deposited on the surface of the silicon oxide layer 3, a lower Al wiring layer, which is exposed at the bottom surface of the via- hole 3a, and the inner surface of the via-hole 3a. The film 5 at the part other than the via-hole 3a is etched with incident ions.

Abstract: PURPOSE:To make the position and width of an output pulse adjustable and to decrease number of externally mounted components to a control terminal by adopting the circuit in which two threshold levels provided with respect to a constant current charging potential to an internal capacitor are adjustable externally. CONSTITUTION:A transistor(TR) (SW) receiving an input trigger pulse 1 is turned on to bring a charging level of an internal capacitor to '0' V. The TR SW is turned off after the trigger pulse 1 is reset and since the internal capacitor C is charged by a constant current from a constant current source 2 fixed in the inside, the terminal level VC of the capacitor increases as time linearly. Only when the level VC crosses threshold levels VH, VL of comparators 9, 10, an output pulse 12 is generated from a logic circuit 11. Since both the potentials VH, VL are controlled by the control terminal 4, a position td of the output pulse 12 from the trigger pulse and an output pulse width tw are adjusted.
