Title: Forming method of gate of semiconductor device
Inventor: JEONG SEONG HUI
IPC: H01L21/24
Filed: 1998-12-17
Abstract: PURPOSE: A gate forming method in a semiconductor device is provided to effectively prevent reflection by a cobalt silicide layer. CONSTITUTION: In a fabrication of a gate, a gate oxide layer(12), a doped polysilicon layer(13), a first metal layer and a second metal layer are successively formed on a substrate(10) having a field oxide layer(11) locally formed therein. While the first metal layer is preferably a titanium layer, the second metal layer is preferably a cobalt layer. Next, a titanium nitride layer as an anti-reflective coating layer is formed on the cobalt layer. Then, a photoresist layer is formed and patterned, and subsequently the titanium nitride layer, the cobalt layer, the titanium layer, and the doped polysilicon layer(13) are etched through the patterned photoresist layer. Next, a heat treatment process is performed such that a stack of the polysilicon layer, the titanium layer and the cobalt layer is changed into a stack of the polysilicon layer, a cobalt-silicon layer and a cobalt-titanium-silicon layer. After removing the cobalt-titanium-silicon layer and the titanium nitride layer, a second heat treatment process is performed to change the cobalt-silicon layer into a cobalt silicide layer(14B).

Title: Connector for torsion beam axle of vehicle
Inventor: CHOI JAE SEOK
IPC: B60G9/00
Filed: 1998-12-18
Abstract: PURPOSE: A connector is provided to increase durability by dispersing stress with a rounding process that recesses the part connecting the torsion beam axel and a trailing arm from the upside to the downside. CONSTITUTION: Stress is easily generated on a narrow and corner part and a fillet part suddenly changing the size and shape of a section. For dispersing stress, the parts are rounded for removing concentrated stress and expanding the stress applied range. A stress dispersing device(222) rounds a connecting part(210) of a torsion beam axle(200). In other words, complex load through a rear wheel is delivered to a trailing arm through a rear wheel carrier and the stress is delivered to the torsion beam axle. The stress is removed from the connecting part since the part is rounded by the stress dispersing device.

If a view point of the observation person varies without changing an object and opaque degree, the on-the-run step is only performed. If the object and opaque degree are changed, the object and the opaque degree to be displayed in the transient processing step are determined again, and then on-the-run processing is performed.
