摘要:
A negative active material for a lithium secondary battery includes a crystalline graphite core and a carbon shell. The carbon shell includes at least one material selected from a transition metal, an alkali metal, an alkaline earth metal, an element of Group 3B of the Periodic table, an element of Group 4B, an element of Group 5B or a mixture thereof. The carbon shell is a turbostratic carbon layer, or am amorphous or crystalline carbon layer having different physical properties from the core. The negative active material can be used in a lithium secondary battery such that the battery has a large discharge capacity and a high charge/discharge efficiency.

A photoresist stripping composition is provided. The composition includes 10-30 weight % of alkanolamine, 10-35 weight % of dimethylsulfoxide, 30-50 weight % of N-methylpyrrolidone and 10-30 weight % of glycolether. The composition shows good stripping force and strips photoresist by a single-wafer treatment method using the air-knife process or by a dipping method.
摘要:
A color filter having patterns for aligning a mask and a method of manufacturing the same. An align key pattern causes a step difference in height of an overlaid resist layer which, in turn, diffracts a laser beam. The diffracted light is detected to generate an alignment signal to which a mask for exposing the subsequent resist layer is aligned.
