Abstract: The present invention relates to an antigen-binding molecule comprising a heavy chain variable region comprising a heavy-chain complementarity-determining region 1 (HCDR1) comprising an amino acid sequence represented by Sequence No. 1, an HCDR2 comprising an amino acid sequence represented by Sequence No. 2, and an HCDR3 comprising an amino acid sequence represented by Sequence No. 3; a light-chain variable region comprising a light-chain complementarity-determining region 1 (LCDR1) comprising an amino acid sequence represented by Sequence No. 4, an LCDR2 comprising an amino acid sequence represented by Sequence No. 5, and an LCDR3 comprising an amino acid sequence represented by Sequence No. 6; wherein the antigen-binding molecule is a T cell receptor (TCR); and to a cell line expressing the same.

Abstract: A semiconductor device including a first source layer including a first part having a first grain size and a second part having a second grain size smaller than the first grain size, a gate structure on the first source layer, and a channel structure passing through the gate structure and the second part of the first source layer.

Abstract: There are provided a memory device and a manufacturing method of the memory device. The memory device includes: a source structure; and a stack structure over the source structure, the stack structure including a plug and a slit, wherein the slit includes a source contact being connected to the source structure.

Abstract: A method of welding a noble metal tip of a spark plug to an electrode is provided. In the method of welding, in a waveform of a power of a laser beam according to a time of the laser welding, a power of a central portion thereof is smaller than those of both end portions thereof. In addition, the waveform of the power of the laser beam according to a time of the laser welding is a trapezoidal waveform which includes: a rising portion in which the power of the laser beam is gradually increased; a power maintaining portion in which the power of the laser beam after the rising portion is maintained uniform; and a falling portion in which the power of the laser beam after the power maintaining portion is gradually decreased.
