    • A wafer demounting receptacle comprises a substantially circular plate member and an upstanding rim structure provided around a periphery of the plate member. The rim structure is stepped and includes a first step defining a first diameter, and a second step defining a second diameter grater than the first diameter. The riser of the first step has a very low height so that a gap between the plate member and a fragile semiconductor wafer bonded to a carrier having a peripheral abutment surface resting on the run of the first step, limits the bending of an edge portion of the wafer in a direction towards the plate member while the wafer is partially demounted from a wafer carrier. The plate member is further provided with a pattern of holes that generates eddy currents in a solvent that flows over the wafer, carrier, and receptacle so as to soften and dissolve the mounting adhesive between the wafer and carrier such that the wafer is separated from the carrier. The wafer demount receptacle can be used in conjunction with a wafer demount tool comprising a chamber defined between a backing plate and a contact plate. The chamber is provided with a gas inlet for introducing a pressurized gas, while the contact plate is provided with a plurality of through-holes. The wafer demount tool is mated to the wafer demount receptacle such that the contact plate is juxtaposed against the back side of a wafer carrier resting in the wafer demount receptacle. Pressurized gas flowing through the wafer demount tool displaces solvent from the wafer-carrier interface to further promote separation of the wafer from the carrier.
    • 晶片拆卸容器包括基本上圆形的板构件和围绕板构件的周边设置的直立边缘结构。 轮辋结构是阶梯式的并且包括限定第一直径的第一步骤和限定比第一直径的第二直径磨浆机的第二步骤。 第一步骤的立管具有非常低的高度,使得板构件和结合到具有搁置在第一台阶的行程上的外围邻接表面的载体的脆弱的半导体晶片之间的间隙限制了第一台阶的边缘部分的弯曲 所述晶片朝向所述板构件的方向,同时所述晶片从晶片载体部分地拆卸。 板构件还设置有孔,其形式在流过晶片,载体和插座的溶剂中产生涡流,以便将安装粘合剂软化并溶解在晶片和载体之间,使得晶片与 载体 晶片卸载插座可以与包括限定在背板和接触板之间的室的晶片拆卸工具结合使用。 该室设置有用于引入加压气体的气体入口,而接触板设置有多个通孔。 晶片拆卸工具与晶片卸载插座相配合,使得接触板与搁置在晶片卸载插座中的晶片载体的背面并置。 流经晶片拆卸工具的加压气体从晶片 - 载体界面排出溶剂,以进一步促进晶片与载体的分离。
