摘要： A cutting apparatus jets, at a high pressure, water containing abrasive grains to cut a workpiece along cutting lines extending in intersecting directions. The cutting apparatus includes: a fixing table fixing the workpiece; groove portions provided in the fixing table at respective positions below the cutting lines; protruded portions provided in regions of the fixing table other than regions where the groove portions are provided, in a manner that the workpiece contacts the protruded portions; support portions provided to connect the protruded portions substantially in parallel with cutting lines extending the Y direction along the groove portions; a frame portion provided to connect the support portions to each other in at least a part of an outer periphery of the fixing table; and protection members attachably and detachably provided to cover the support portions. Thus, in the case where the workpiece is cut along the intersecting cutting lines, replacement of the fixing table fixing the workpiece is unnecessary and wear of the fixing table is prevented.

摘要： A resin-sealing mold for encapsulating a semiconductor device includes upper and lower molds with a first cavity insert forming a cavity side face portion; a first elastic post supporting the first cavity insert; an elastic plate, built in the first cavity insert, forming a cavity bottom portion; a second cavity insert embedded at a position adjacent to the elastic plate on the side opposite to the cavity; a second elastic post supporting the second cavity insert; a retainer including the first cavity insert and the second cavity insert; and a backing plate to which the first elastic post, the second elastic post and the retainer are attached. Generation of thin burrs that tend to appear on the periphery of the package and in the vicinity of the cull section is prevented, and, consequently, a resin-sealing mold with high reliability is produced.
