Abstract: Polishing pad and method of manufacturing the same, the method, whereby materials for forming a polishing layer are mixed and solidified by a chemical reaction so as to manufacture the polishing pad, the method including: grinding organic materials by using a physical method so as to form micro-organic particles; mixing the micro-organic particles formed in the operation with the materials for forming the polishing layer; mixing at least one selected from the group consisting of inert gas, a capsule type foaming agent, and a chemical foaming agent that are capable of controlling sizes of pores, with the mixture in the operation so as to form gaseous pores; performing gelling and hardening of the mixture generated in the operation so as to form a polishing layer; and processing the polishing layer so as to distribute open pores defined by opening gaseous pores on a surface of the polishing layer.

Abstract: Polishing pad and method of manufacturing the same, the method including: (a) mixing materials for forming a polishing layer; (b) mixing at least two from among inert gas, a capsule type foaming agent, a chemical foaming agent, and liquid microelements that are capable of controlling sizes of pores, with the mixture in (a) so as to form two or more types of pores; (c) performing gelling and hardening of the mixture generated in (b) so as to form a polishing layer including the two or more types of pores; and (d) processing the polishing layer so as to distribute micropores defined by opening the two or more types of pores on a surface of the polishing layer.

Abstract: An image processing apparatus is provided that includes a main memory; at least one sub-memory that stores data, a cache memory that temporarily stores data, and controller that controls whether to temporarily store the data in the cache memory selectively with respect to each of the at least one sub-memory.

Abstract: An apparatus and method for managing stacks for efficient memory usage. The apparatus includes a fault cause analysis unit to recognize a page fault caused by a marking page; a control unit to set the marking page, to request compression of a first stack page depending on whether a page fault occurs, to release a mapping of a second stack page that becomes empty due to the compression, and to return the second stack page; a memory allocation unit to receive the second stack page and to allocate a new stack page to the control unit upon completion of the compression; and a compression unit to compresses the first stack page at the request of the control unit.
