Title: Etching apparatus
Inventor: SUGIZAKI DAISUKE
IPC: H01L21/306
Filed: 2019-03-01
Abstract: To provide a technique capable of improving etching uniformity for the surface of a semiconductor wafer.SOLUTION: An etching apparatus has a storage tank for storing etching liquid, a support tool, a light source, a counter electrode, and a power supply. The support tool supports a semiconductor wafer rotatably in a state where the first surface of the semiconductor wafer is immersed in the etching liquid. The light source irradiates the first surface of the semiconductor wafer, supported by the support tool, with light. The counter electrode is placed in the storage tank, between the support tool and the light source, at a position separated from the first surface of the semiconductor wafer supported by the support tool. The light source applies a voltage between the semiconductor wafer supported by the support tool and the counter electrode. When the light source emits light, irradiation range of light and electrode shadow are projected on the first surface of the semiconductor wafer supported by the support tool. When the semiconductor wafer is rotated by the support tool, at least a part of the first surface passes through both the irradiation range and the shadow.SELECTED DRAWING: Figure 3
