Abstract: In a method of manufacturing a photo mask, a resist layer is formed over a mask blank, which includes a mask substrate, a phase shift layer disposed on the mask substrate and a light blocking layer disposed on the phase shift layer. A resist pattern is formed by using a lithographic operation. The light blocking layer is patterned by using the resist pattern as an etching mask. The phase shift layer is patterned by using the patterned light blocking layer as an etching mask. A border region of the mask substrate is covered with an etching hard cover, while a pattern region of the mask substrate is opened. The patterned light blocking layer in the pattern region is patterned through the opening of the etching hard cover. A photo-etching operation is performed on the pattern region to remove residues of the light blocking layer.

Abstract: This disclosure presents a composition for tissue staining and 3D specimen optical clearing, along with a method of making biological material transparent and labeling it simultaneously. The composition includes an amide dye adjuvant, a RI-matching material, a permeating agent, a labeling material, a mixture homogeneity excipient, and a solvent with DMSO. The RI-matching material includes a contrast agent and sugar. The composition has a neutral or acidic pH. The method involves fixing a specimen with a fixative solution and immersing and incubating the specimen in the composition for permeation. This disclosure also presents a kit for rendering biological material transparent. The kit is helpful for experimental animal/human histological studies and cancer staging/tumor differentiation determination.

Abstract: A ferroelectric memory device and a semiconductor die are provided. The ferroelectric memory device includes a gate electrode; a channel layer, overlapped with the gate electrode; source/drain contacts, in contact with separate ends of the channel layer; a ferroelectric layer, lying between the gate electrode and the channel layer; and a first insertion layer, extending in between the ferroelectric layer and the channel layer, and comprising a metal carbonitride or a metal nitride.

Abstract: An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.

Abstract: A conductive pad structure, configured in a peripheral circuit area of a device substrate, is provided. The conductive pad structure includes a conductive pad and a plurality of conductive spacers. The conductive spacers are configured on the conductive pad and arranged as a non-closed pattern on the conductive pad.
