  • Patent number: 10854431
    Abstract: A plasma processing method includes executing an etching process that includes supplying an etching gas into a process container in which a target substrate is supported on a second electrode serving as a lower electrode, and applying an RF power for plasma generation and an RF power for ion attraction to turn the etching gas into plasma and to subject the target substrate to etching. The etching process includes applying a negative DC voltage to a first electrode serving as an upper electrode during the etching to increase an absolute value of self-bias on the first electrode. The etching process includes releasing DC electron current generated by the negative DC voltage to ground through plasma and a conductive member disposed as a ring around the first electrode, by using a first state where the conductive member is connected to a ground potential portion.

  • Publication number: 20190219799
    Abstract: An image-pickup optical system includes: a first lens provided near an aperture stop and configured to correct aberration; and a second lens arranged between the first lens and an image sensor and configured to collect light, the first lens being a gradient index lens. The degree of freedom of design of a gradient index lens is higher than that of a lens having a constant refractive index, and a gradient index lens thus has a high potential as a device for a lens. Because such a gradient index lens is employed, it is possible to correct aberration without performing expensive processing such as polishing for example. In other words, as a result, costs may be reduced and image-forming properties may not be reduced at the same time.
