Argon plasma used only for the purpose of hardening the photoresist and oxygen plasma used for etching the hardened resist. However, the two-stage alternative is not preferred because the etched photoresist profiles were found to be less vertical that combined O 2 and Ar plasma. 3.2.
WebThe methodology enables the use of optical emission spectroscopy and/or optical interferometry techniques for endpoint monitoring during resist trim etching of photoresist structures. Various types of material layers underlying photoresist structures are employed in order to provide an endpoint signal to enable closed loop control, with resultant … WebGeneral Information. AZ ® BARLi ® - II is a bottom antireflective layer coating for use on highly reflective surfaces in the semiconductor industry. It is designed to work with positive photoresists and is optimized for i-line exposure tools. Upon completion of the lithographic process, AZ ® BARLi ® - II is patterned in a dry-etch process.

Web1. A method for forming a stair-step structure in a substrate, comprising: a) forming an organic mask over the substrate; b) forming a hardmask with a top layer and a sidewall layer over a top and a sidewall of the organic mask; c) removing the sidewall layer of the hardmask while leaving the top layer of the hardmask; d) trimming the organic mask; e) … WebNon-cross-linked AZ® and TI photoresist fi lms generally can be removed without residue after processing using common removers. If this does not work satisfyingly, the following possible reasons should be con-sidered: Positive resists begin to thermally cross-link from about 140°C (e.g. during hardbaking, dry etching or
