Abstract:
A semiconductor device according to an embodiment is a semiconductor device in which a semiconductor chip mounted on a chip mounting part is sealed by resin and a first member is fixed to a chip mounting surface side between a peripheral portion of the semiconductor chip and a peripheral portion of the chip mounting part. Also, the first member is sealed by the resin. Also, a length of the first part of the chip mounting part in the first direction is larger than a length of the semiconductor chip in the first direction, in a plan view.
Abstract:
A semiconductor device has a base material (BS) comprised of insulating material having a through hole (SH), a terminal (TE) formed on a lower surface of the base material (BS), and a semiconductor chip mounted on an upper surface of the base material in a face-up manner. Further, the semiconductor device has a conductive member (BW) such as a wire, which electrically connects a pad of the semiconductor chip with an exposed surface of the terminal which is exposed from the through hole (SH) of the base material (BS), and has a sealing body (MR) for sealing the conductive member (BW), inside of the through hole (SH) of the base material (BS), and the semiconductor chip. An anchor (SB) means is provided in a region of the exposed surface (EX(TEa)) of the terminal (TE) which is exposed from the through hole (SH) of the base material (BS) except for a joint portion (BL) joined with the conductive member (BW) such as the wire. In this way the adhesiveness between the exposed surface (EX(TEa) of the terminal (TE) is increased so that the reliability of the semiconductor device may be improved.
Abstract:
The invention relates to a method for manufacturing a card connector or a card comprising the step of depositing layers (31,32,33,34,35) of connector materials onto a substrate (10) so as to form a pattern of contacts (30) for a connector. It also comprises the step of removing the substrate (10) from the pattern of contacts (30) so as to expose the contacts (30). The substrate to be removed (10) is made of conductive material. The method comprises the step of depositing at least one layer (31,32,33,34,35) of the pattern of contacts (30) by electro-deposition by making use of the substrate to be removed (10) as a conductor for electric current used in the electro-deposition. The invention may also comprise the step of overmolding the card body compound, after having mounted and connected a chip to the connector, and before peeling off the substrate.
Abstract:
A lead frame includes a plurality of leads (10) defined by an opening (11) extending in a thickness direction. An insulating resin layer (20) fills the opening to entirely cover side surfaces (10C) of each lead and to support the leads. A first surface (10A) of each lead is exposed from a first surface (20A) of the insulating resin layer (20).
Abstract:
A semi-conductor device (100) comprises an exposed leadframe (10) with a die pad (11) and a plurality of leads (12). The die pad (11) has a substantially flat bottom surface (14) and a top surface (15). A semi-conductor die (2) is attached to a die attachment portion (31) of the top surface (15). Downbonds (5) connect the die (2) to a downbond attachment portion (32). Standard bonds (4) connect the die (2) to the leads (12). A plastic package (6) encapsulates the die (2), the standard bonds (4) and the downbonds (5). The top surface of the die pad has portions located at different levels, and step-shaped transitions between two adjacent ones of such portions. At least one of such step-shaped transition (36) is located between the die (2) and the downbonds (5). It has been found that such step-shaped transition provides good protection against downbond failure.
