Title: Method for forming metal line using dual damascene
Inventor: JUNG YONG SIK
IPC: H01L21/28
Filed: 2000-12-28
Abstract: PURPOSE: A method for fabricating a metal interconnection by using a dual damascene process is provided to reduce resistance of the metal interconnection by using copper, and to use a dielectric material of a low dielectric constant by obviating the necessity of an additional metal material for filling a gap. CONSTITUTION: A semiconductor substrate(21) is prepared. The first nitride layer, the first oxide layer, the second nitride layer and the second oxide layer are sequentially formed on the semiconductor substrate. The first photoresist layer pattern is formed on the second oxide layer. The second oxide layer, the second nitride layer and the first oxide layer are sequentially patterned to form a contact hole by using the first photoresist layer pattern as a mask. The first photoresist layer pattern is removed. An insulation layer spacer is formed on the sidewall of the contact hole. The second photoresist layer pattern is formed on the second oxide layer. The second oxide layer, the second oxide layer, the insulation layer spacer, the first oxide layer and the first nitride layer are sequentially patterned to expose the semiconductor substrate by using the second photoresist layer pattern as a mask. A barrier metal layer(37) and a copper layer(39) are formed on the resultant structure and are planarized by a chemical mechanical polishing(CMP) process.

An activation layer is formed to enclose the entire surface of the resultant structure except for the photoresist pattern region by activating the surface with Pd grains through an activation bath. Then, the photoresist pattern is removed and a copper layer(15) is then formed to completely enclose the resultant structure by dipping into a bath(18) having an electroless copper plating solution(19). After remaining the copper layer(15) only on the front surface of the resultant structure, copper interconnections are formed by a polishing process.

Abstract: PURPOSE: A door type interception system for a railway crossing is provided to prevent effectively a collision between a vehicle and a train by sensing an approaching state and a traveling speed of a train passing the railway crossing by stages. CONSTITUTION: A plurality of up train sensors(SA1,SA2,SA3) is installed at remote places from an up line of a railway crossing in a predetermined interval, respectively. An up train approach sensor(SA4) is installed at a near place from the railway crossing. A plurality of down train sensors(SB2,SB3,SB4) is installed at remote places from a down line of the railway crossing in a predetermined interval, respectively. A down train approach sensor(SB1) is installed at a near place from the railway crossing. A train speed sensor portion(VR) is installed around a railroad in which the up train sensor(SA1) is installed. The first alarm generation portion(A1), the first cutoff(C1), and the second cutoff(C2) are installed at a vehicle approach road of the railway crossing. The second and the third alarm generation portions(A2,A3) are installed at a remote place from the railway crossing. A signal lamp(TR) is installed at a crossroad.
