摘要: A photoresist pattern is formed on a quartz substrate. The quartz substrate is dipped into a silicon oxide supersaturated solution of hydrofluoric acid, and a silicon oxide is precipitated out of the supersaturated solution, thereby forming an SiO.sub.2 film on that exposed surface of the quartz substrate which is not covered with the photoresist pattern. After that, the photoresist pattern is ashed by oxygen plasma, and the ashed pattern is removed. The SiO.sub.2 film remaining on the quartz substrate serves as a phase shifter.

摘要: Disclosed is a method of forming a silicon oxide film on a silicon wafer, comprises the steps of keeping a supersaturated hydrofluoric acid solution of silicon oxide on the surface of a silicon wafer in a thickness of not more than 20 mm, the solution having a predetermined temperature, heating the supersaturated solution until the solution reaches a thermal equilibrium, and maintaining for a predetermined period of time the temperature at which a thermal equilibrium is established in the supersaturated solution so as to form a silicon oxide film on the surface of the silicon wafer.

摘要: A photoresist layer having a prescribed pattern is formed on a substrate to be etched. The substrate is immersed into a predetermined solution to form a layer on the substrate except on those portions where the photoresist layer is formed. The photoresist layer is removed, and the substrate is etched using the remaining layer as a mask.

摘要: A process for manufacturing a copper-clad laminate which includes a rolled copper foil as a circuit conductive material comprising, introducing a rolled copper foil through a power supply/guide roller into an electrolyte so as to pass between two parallel electrodes which are disposed in the electrolyte. An AC, DC or a combination thereof is supplied to the power supply/guide roller and the electrodes to form an etched layer on either one or both sides of the rolled copper foil. An adhesive is applied to the etched layer and the resultant rolled copper foil is pressed with a substrate made of a synthetic resin put together to form a laminate.
