Abstract:
PURPOSE: A method for inspecting a chip stack semiconductor device and a method for manufacturing the chip stack semiconductor device using the same are provided to manufacture the chip stack memory device using chips without defects of a through silicon via by checking the defects of the through silicon via for connecting chips before an upper chip is bonded to a lower chip. CONSTITUTION: A first chip(50) is formed on a substrate(10) and includes a through silicon via(12), a first pad electrode, a probe pad electrode(18), and a micro bump pad(20). An inspection chip(80) including a second pad electrode(62) is contacted with the upper side of the first pad electrode. A laminate structure is formed to expose a probe pad electrode to the outside. The through silicon via included in the first chip is inspected by applying an electric signal to the exposed probe pad electrodes. The first chip and the inspection chip are separated if the through silicon via is defective.
Abstract:
PURPOSE: A semiconductor chip, a stack module, a memory card, and a manufacturing method thereof are provided to prevent the electrical resistance increase of an electrode by arranging a burying part which has a uniform width. CONSTITUTION: A substrate(105) comprises a first and a second side. A via electrode(150) is arranged in order to bury at least one via hole(135). The via electrode is extended from the first side of the substrate. The via electrode comprises a first burying part(152), a second burying part(154), and/or a protrusion part(156). The via hole comprises a first part(126) and a second part(132). The via hole is vertically extended from the first side of the substrate and the second side.
Abstract:
PURPOSE: A chip stack package and a fabrication method thereof are provided to prevent a fault due to the defect of a PCB by preventing the deterioration of moisture absorption rate of the PCB. CONSTITUTION: In a stacked chip package and a manufacturing method thereof, a base chip(120), a connection terminal, and an outside encapsulating material are included therein. The base chip has a base through via electrode, a base chip pad, and a base encapsulating material(116). The connecting terminal is protruded from the base encapsulating material while being connected to the base through via electrode and the base chip pad. The outside encapsulating material surrounds the outside of the base chip and the stacked chips.
Abstract:
PURPOSE: A method of chip interconnection using a capillary phenomenon is provided to simplify a process by forming a contact electrode through a capillary phenomenon and connecting semiconductor chips each others at the same time. CONSTITUTION: A first semiconductor device includes a first TSV(THROUGH SILICON VIA)(TSV) are formed. Solder balls are located in the first TSV respectively. A back-lap of the first semiconductor device is progressed. A second semiconductor device(110) having a second via hole therein is formed on the first semiconductor device. A reflow process is progressed and the solder balls are fused. The solder balls fills up the first and the second via hole through a capillary phenomenon.
