    摘要: A method of etching a semiconductor device having multi-layered wiring by an ion beam is disclosed which method comprises the steps of: extracting a high-intensity ion beam from a high-density ion source; focusing the extracted ion beam; causing the focused ion beam to perform a scanning operation by a voltage applied to a deflection electrode; forming a first hole in the semiconductor device by the focused ion beam to a depth capable of reaching an insulating film formed between upper and lower wiring conductors so that the first hole has a curved bottom corresponding to the undulation of the upper wiring conductor, and the upper wiring conductor is absent at the bottom of the first hole; and scanning a portion of the bottom of the first hole with the focused ion beam to form a second hole in the insulating film to a depth capable of reaching the lower wiring conductor, thereby preventing the shorting between the upper and lower wiring conductors. Further, a method of forming a hole of a predetermined shape at a surface area having a step-like portion of a semiconductor device by an ion beam is disclosed which method comprises a pre-etching step of scanning the high-level region of the step-like portion with the ion beam so that the high-level region becomes equal in level to the low-level region of the step-like portion, and a main step of scanning the whole of the surface area with the ion beam till the hole of the predetermined shape is formed in the semiconductor device.

    摘要: A semiconductor IC device having a substrate, a patterned conductor layer for interconnection of regions in the substrate and a passivation layer covering the device is provided with an additional conduction path of a pattern and/or part of the patterned conductor layer is removed for disconnection for the purpose of evaluation of the characteristics of the device. The additional conduction path is formed by forming a hole in the passivation layer to expose a part of the conductor layer, directing, in an atmosphere containing a metal compound gas, an ion beam onto the hole and onto a predetermined portion of the passivation layer on which the additional conduction path of a pattern is to be formed to thereby form a patterned film of the metal decomposed from the metal compound gas and forming an additional conductor on the patterned film. The provision of the additional conduction path and/or the removal of part of the patterned conductor layer is preformed in a chemical vapor deposition apparatus which includes a vacuum chamber and an ion beam radiation unit having a housing partitioned into, for example, first, second and third compartments. The ion beam radiation unit has an ion source placed in the first compartment, an ion beam focusing and deflecting device placed in the second compartment and pressure buffer constituted by the third compartment. The third compartment is coupled to and pneumatically isolated from the vacuum chamber for conducting an ion beam emitted from the ion source, passing the second compartment and ejected from the second compartment to the vacuum chamber.

    摘要: A processing method and apparatus using a focused energy beam for conducting local energy beam processing in a focused energy beam irradiating area by irradiating a sample with a focused energy beam such as an ion beam or an electron beam in an etching gas atmosphere. As the etching gas, a mixed gas different in composition from any conventional one is employed and the gas is uniformly supplied to an etching area and at least one of the components of such a mixed gas is a spontaneous reactive gas for use in etching the sample spontaneously and isotropically. With this arrangement, it is possible to subject to local etching a material for which the local etching has been impossible to provide since a single etching gas causes a reaction too fierce or causes almost nearly no reaction.

    摘要: The present invention relates to a semiconductor integrated circuit device and a process for producing the same. A hole is bored in an insulating film above a portion of a wiring which is to be connected to another wiring by means of a focused ion beam. The inside of the hole and a predetermined region on the insulating film are irradiated with either a laser beam or an ion beam in a metal compound gas to deposit metal in the hole and on said region and a connecting wiring is formed by means of optically pumped CVD. To electrically connect upper- and lower-level wirings in a multilayer wiring structure by a connecting wiring, the connecting wiring is electrically isolated from an intermediate-level wiring through which it extends. The above-described arrangement enables provision of a hole with a focused ion beam and formation of a metal wiring on a selective region by means, for example, optically pumped CVD. Accordingly, it is possible to effect fine machining and electrically connect together wirings inside an LSI after the completion thereof. It is therefore possible to carry out debugging, repair and a defect analysis of the LSI.
