    摘要: A Si etching method etches a Si wafer held on a susceptor placed in a processing vessel by a plasma-assisted etching process. A mixed etching gas prepared by mixing fluorosulfur gas, such as SF6 gas, or fluorocarbon gas, O2 gas and fluorosilicon gas, such as SiF4 gas is supplied into the processing vessel. RF power of 40 MHz or above is applied to the mixed etching gas to generate a plasma. The Si wafer is etched with radicals and ions contained in the plasma.

    摘要: An etching method for forming a recess (220) having an opening dimension (R) of millimeter order in an object (212) to be etched such as a semiconductor wafer. A mask (214) having an opening corresponding to the recess (220) is formed on the object (212). The object (212) with the mask (214) is placed in a processing vessel for plasma etching and etched in it using a plasma. The material of the portion around the opening of the mask (214) is the same as the material, for example, silicon of the object (212). Hence, the recess (220) can be so formed as not to form a sub-trench shape (a shape formed by etching the periphery of which is deeper than the center) substantially in the bottom (222).

    摘要: This invention provides the following high-rate silicon etching method. An object to be processed W having a silicon region is so set as to be in contact with a process space in a process chamber that can be held in vacuum. An etching gas is introduced into the process space to form a gas atmosphere at a gas pressure of 13 Pa to 1,333 Pa (100 mTorr to 10 Torr). A plasma is generated upon application of RF power. In the plasma, the sum of the number of charged particles such as ions and the number of radicals increases, and etching of the silicon region is performed at a higher rate than in conventional etching.

    摘要: An etching method forms an opening with a substantially vertical profile extending to a stopper layer by performing an etching with a plasma of an etching gas acting on an object to be processed loaded in an evacuable processing vessel, wherein the object has a mask layer of a predetermined pattern, a silicon layer to be etched formed below the mask layer and the stopper layer formed below the silicon layer. The etching method includes a first etching process for forming an opening with a tapered wall surface in the silicon layer by using a first etching gas including a fluorine-containing gas and O2 but not HBr; and a second etching process for etching the opening by using a second etching gas including a fluorine-containing gas, O2 and HBr.
