Then, the first masking layer and a portion of the second masking layer which includes a portion which covers the first masking layer is removed, a third metal layer is formed on portions of the first and second metal layers which are exposed by the step of removing the first masking layer and the portion of the second masking layer. Finally, the second masking layer, the second metal layer; and the first metal layer except a portion which the third metal layer covers are removed. In this way, the area for integrating various passive elements can be saved and the overall area for the semiconductor device including the integrated circuit and the passive elements may be reduced.

    摘要: There are disclosed methods for the prevention of misfit dislocation in a silicon wafer and the silicon wafer structure manufactured thereby. A method according to an embodiment comprises the steps of: depositing a blanket silicon oxide or silicon nitride on silicon wafer in a chemical vapor deposition process; selectively etching the silicon oxide or silicon nitride, to form a silicon oxide or silicon nitride pattern which is of close shape; and injecting the silicon wafer with impurities at a high density with the CVD silicon oxide or silicon nitride pattern serving as a mask, so as to form an impurity-blocked region is formed under the CVD silicon oxide or silicon nitride through the action of the mask. The misfit dislocation is propagated mainly from the edge of wafer and an impurity-blocked region can prevent the propagation. The propagation energy is virtually based on the tensile stress attributable to the implantation of impurity. Formation of an impurity-blocked region in the wafer barricades the propagation of misfit dislocation because the propagation energy is not supplied in this region. Thus, the area of the silicon wafer enclosed by the impurity-blocked region has no misfit dislocation. By such conception, a silicon wafer free of misfit dislocation can be manufactured. Therefore, there are improved in electrical and mechanical properties in electrical devices, X-ray masks and micromachines as well as in surface roughness.

A first switch and a third switch connect and disconnect a first reference voltage and a second reference voltage such that the same current flows in the sources of the first and second transistors. A first capacitor charges the voltage between the gate and the source of the first transistor, and a second capacitor charges the voltage between the gate and the source of the second transistor. A second switch switches an application of the input voltage to the input stage of the push-pull circuit, and a fourth switch switches a charge of voltages between the gates and the sources of the first and second transistors in the first and second capacitors.

    摘要: A digital driving circuit for a liquid crystal display which sequentially receives and displays n-bit digital video information from a data bus on a bit basis. The digital driving circuit comprises a first data latch for sequentially storing the digital video information from the data bus on a bit basis, a shift register for synchronizing a latching operation of the first data latch with bit positions of the digital video information from the data bus, a second data latch for storing the digital video information stored in the first data latch temporarily before digital/analog conversion, and a digital/analog converter for sequentially converting the digital video information stored in the second data latch into analog signals on a bit basis. The digital driving circuit is able to sequentially process bit information of digital video information to reduce the number of data bus lines for loading the bit information thereon and the number of data catches arranged vertically to a column direction. Therefore, the driving circuit can be significantly reduced in its occupying width, thereby making it possible to make the display higher in density.

    摘要: The present invention relates to a method of forming a small gap using CMP and a method for manufacturing a lateral FED. In the present invention, a small gap is determined by the thickness of an oxide film, and so uniform small gaps of about 100 Å that have been impossible to attain with the art of prior lithography can be formed with repeatability. Prior lateral field emission devices have the problem of repeatability in forming a gap for field emission because they are fabricated by means of a thermal stress method or an electrical stress method. But if the method of forming a small gap according to the present invention is used to fabricate a lateral FED, a FED can be made that has low voltage drive and high current drive characteristics and uniform field emission characteristics.

According to a first embodiment of the present invention, in the steps for forming an improved metal barrier layer, which is comprised of the conventional barrier layer and the conventional nozzle plate combined together, the metal barrier layer can be formed on a wetting layer by using electrolytic plating or electroless plating of Ni. As a result, an upper surface of a first photoresist mold is completely covered with the overflowing Ni. Further, an upper portion of a second photoresist mold is partially covered with the overplating Ni and is partially opened at a proper size and a desired shape. Thereby, an ink ejecting orifice is created at the upper portion of the second photoresist mold. Alternatively, according to a second embodiment of the present invention, by forming a third photoresist mold at a predetermined position in which the ink ejecting orifice will be formed, the overflowing Ni is formed around the third photoresist mold, and thereby the ink ejecting orifice is created. The ink ejecting orifice has a desired shape, a uniform size and a high sectional height, which are adapted to provide an optimum ejection of the ink.

    摘要: A method of fabricating a refractive silicon microlens by using micro-machining technology. The method of fabricating a refractive silicon microlens according to the present invention comprises the steps of forming a boron-doped region on a silicon substrate, and selectively removing regions of the substrate except for the boron-doped region to form a lens comprised of only the boron-doped region. With the method of the present invention, it is possible to fabricate a two-dimensional infrared silicon microlens array. By using such a two-dimensional infrared silicon microlens array in an infrared sensor, the detectivity of the infrared sensor can be increased by 3.4 times, which is the refraction index of silicon. In addition, the two-dimensional infrared silicon microlens array of the present invention can be used with commercial infrared telecommunication devices.
