Critical dimension uniformity

The present disclosure describes a method for improving post-photolithography critical dimension (CD) uniformity for features printed on a photoresist. A layer can be formed on one or more printed features and subsequently etched to improve overall CD uniformity across the features. For example the method includes a material layer disposed over a substrate and a photoresist over the material layer. The photoresist is patterned to form a first feature with a first critical dimension (CD) and a second feature with a second CD that is larger than the first CD. Further, a layer is formed with one or more deposition/etch cycles in the second feature to form a modified second CD that is nominally equal to the first CD.

Methods for manufacturing high-density neural probes having various forms

Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.

20200401051 · 2020-12-24 ·

A method for figure correction of an optical element includes forming a masking layer on a surface of the optical element. The optical element has thinning regions and non-thinning regions. The masking layer is patterned to form masking regions and non-masking regions, and the masking layer is positioned relative to the optical element in such a manner that the masking regions corresponds to the non-thinning regions of the optical element and the non-masking regions corresponds to the thinning regions of the optical element. The method further includes performing reactive ion etching on the optical element provided with the masking layer so as to etch the thinning regions of the optical element to reduce a thickness of the thinning region.
