IPC: H01H85/00
Filed: 1998-06-30
Abstract: PURPOSE: A circuit for programming an anti-fuse is provided to vary a voltage level of an inner voltage generator to program an anti-fuse and cut a current path to reduce a current dissipation CONSTITUTION: A circuit for programming an anti-fuse includes a variable voltage generating portion(10) for a voltage level to vary according to a programming signal, a buffing portion(20), an operation switching portion(30), an anti-fuse, a sense signal inputting portion(40), a breakdown voltage supplying portion(50), an output portion(80), a current cutting portion(60), and a latching portion(70). The buffing portion buffers an output signal of the variable voltage generating portion. The operation switching portion precharges with the power of the variable voltage generating portion. The anti-fuse generates an insulation breakdown when over-current is flowed. The sense signal inputting portion is inputted a sensing signal to confirm the program state of the anti-fuse. The breakdown voltage suppling portion supplies the voltage of the variable voltage generating portion. The output portion outputs the program state of the anti-fuse. The current cutting portion cuts or connects a path of the current being supplied from the breakdown voltage suppling portion to the anti-fuse. The latching portion strongly maintains the voltage of the variable voltage generating portion to the anti-fuse.

Title: Method for forming thin film of semiconductor device using slope
Inventor: YOO BONG YOUNG
IPC: H01L21/31
Filed: 1998-08-27
Abstract: PURPOSE: The method forms a thin film of a semiconductor device using a slope capable of obtaining good step coverage through the desired whole area. CONSTITUTION: A thin film(48) is formed as varying the state between source particles(46) for the thin film formation and a substrate(40) to a vertical state and to a sloped state. The thin film is formed by controlling the vertical state and the sloped state appropriately. In case that the thin film is formed in the vertical state, the thin film is formed by rotating the substrate on the center of an axis vertical to the substrate in he vertical state. By doing so, an equal opportunity to form the thin film is given to the bottom and to the side of a contact hole(44). Thus, the formation of the thin film having a uniform thickness over the whole surface is enabled and the step coverage of the thin film is improved. Thus, the method can suppress the oxide diffusion of a plug material in the process of forming a plug in the contact hole and can proceed more stable plug formation process by making the deposition thickness of a side of a layer deposited in the initial low temperature thick sufficiently in a hot temperature fill process.
