Title: Formation of t-shaped pattern
Inventor: NAKANO HIROBUMI
IPC: H01L21/338
Filed: 1991-06-14
Abstract: PURPOSE:To eliminate film exhaustion of lower layer resist at the time of development of upper layer resist, by constituting the lower layer out of two- layered resist as resist having sensitivity to an electron beam, constituting the upper layer as resist having sensitivity to ultraviolet radiation, exposing the upper layer resist to ultraviolet radiation, and writing an image on the lower resist with an electron beam. CONSTITUTION:Out of two-layered resist, the lower layer is EB resist 2 and the upper layer is photo resist 3. The upper layer photo resist 3 is exposed to ultraviolet radiation, and the lower layer EB resist 2 is subjected to image wiring by an electron beam. By exposing the photo resist 3 to ultraviolet radiation, high throughput formation is enabled. At the time of development of the photo resist 3, the film exhaustion of the EB resist 2 is not generated. That is, the resist thickness of the EB resist 2 is stabilized. Since the EB resist 2 is patterned after the development of the photo resist 3, a minute aperture part can be formed. Hence the distance between a T-shaped electrode and a substrate is stabilized, and the irregularity of characteristics of a completed device is not generated.

IPC: B66D3/04
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent the sliding damage of a rope so as to improve durability by forming a groove V-shaped in section in the outside of a winding drum at a pitch larger than the diameter of a rope, and winding the rope to bite in. SOLUTION: Projecting and recessed parts are formed to have a groove V-shaped in section at a pitch larger than the diameter of a rope 3 in the outer periphery of a winding drum 1. The rope 3 is wound on this V-shaped groove 6 to bite in the same. In this way, a wedge effect is generated to increase friction resistance. Also, a plurality of pins 8 are disposed through the centers of the winding drum and a main spindle, and these are firmly connected to each other without any play in a rotational direction. A shearing force between the winding drum 1 and the main spindle is increased, and rotational torque is increased. Holes are bored in both ends of each pin 8, the hole of the inserted pin 8 is expanded by hitting the same with a punch, and the pin 8 bites in the winding drum 1 and then is fixed so as not to be pulled out.  Recessed and projecting parts are formed in a guide roller corresponding to the projecting and recessed parts of the winding drum 1, and placed oppositely thereto. Thus, the sliding and damaging of the rope are prevented.
