摘要:
An electrolytic etching method for etching treating an object to be etched by an electrochemical reaction through an electrolyte between the object to be etched and an etching electrode, where the contact angle of the electrolyte to the object to be etched is not more than 70°. This electrolytic etching method can etch the object in a non-contact manner, can reduce the cost, number of steps, and processing time, and can enhance the patterning accuracy.
摘要:
Provided is a method of manufacturing an optical element having a structure, which is represented by a one-dimensional lattice, with high yield with the use of a sol-gel material. A titanium based sol-gel material is applied onto a substrate (1), and then is subjected to vacuum drying to form a titania sol layer (2) corresponding to a dried sol-gel film. Onto the titania sol layer (2), a line-and-space structure is transferred by embossing using a mold (3), and then the mold (3) is separated. Thus, a titania sol layer (4) having the structure is formed. Next, heating is performed to accelerate the dehydration condensation reaction of the sol-gel material to cure the sol-gel material, and thus a titanium oxide structure portion (5) having the line-and-space structure is formed.
摘要:
An electrode structure is constituted by a first electrode, and at least one second electrode providing a pair of opposite portions with a prescribed spacing therebetween at which the first electrode is disposed. The electrode structure is suitably used for electrolytic etching and is effective in providing an accurate etching pattern without damaging the surface of an etching object.
摘要:
A method for etching an object having a portion to be etched on the surface thereof, comprising a step of immersing said object in an electrolyte solution such that said object serves as a negative electrode; a step of arranging a counter electrode having a pattern corresponding to a desired etching pattern to be formed at said portion to be etched of said object in said electrolyte solution so as to maintain a predetermined interval between said counter electrode and said object, and a step of applying a direct current or a pulse current between said object and said counter electrode to etch said portion to be etched of said object into a pattern corresponding to said pattern of said counter electrode.
摘要:
An etching apparatus is described comprising a substrate holding segment for holding a substrate with a portion to be etched, an electrolytic bath for maintaining an electrolyte solution therein, a locomotive mechanism for moving the substrate holding segment in order to immerse the substrate held on the substrate holding segment in the electrolyte solution maintained in the electrolytic bath, and a counter electrode holding segment for holding a counter electrode having a pattern corresponding a desired etching pattern to be formed at the portion to be etched of the substrate. The counter electrode is positioned to oppose the substrate held on the substrate holding segment.
