Abstract: In some embodiments, the present disclosure relates an integrated chip including a substrate. A conductive interconnect feature is arranged over the substrate. The conductive interconnect feature has a base feature portion with a base feature width and an upper feature portion with an upper feature width. The upper feature width is narrower than the base feature width such that the conductive interconnect feature has tapered outer feature sidewalls. An interconnect via is arranged over the conductive interconnect feature. The interconnect via has a base via portion with a base via width and an upper via portion with an upper via width. The upper via width is wider than the base via width such that the interconnect via has tapered outer via sidewalls.

Abstract: The present disclosure provides an apparatus for a lithography process in accordance with some embodiments. The apparatus includes a pellicle membrane, a pellicle frame including a material selected from the group consisting of boron nitride (BN), boron carbide (BC), and a combination thereof, a mask, a first adhesive layer that secures the pellicle membrane to the pellicle frame, and a second adhesive layer that secures the pellicle frame to the mask.

Abstract: A method for generating a search index, applicable for a database system having a first database and a second database, includes the follow steps: receiving an access instruction corresponding to a first document, analyzing the first document to obtain a plurality of key character strings, writing the first document into the first database or the second database based on the access instruction and generating address information corresponding to the first document accordingly, and generating a search index corresponding to the first document based on the address information and the key character strings.

Abstract: An oral pharmaceutical composition for the treatment of digestive tract cancers contains an effective amount of a camptothecin derivative dissolved in a non-aqueous solvent. The camptothecin derivative is administered at a dose of about 0.05 to about 1 mg/kg body weight/day. The pharmaceutical composition is particularly suitable for use in low-dose-long-term regimens for colorectal cancers.
