Abstract:
PROBLEM TO BE SOLVED: To provide a compact high-density storage device having a plug and a socket for connecting the other storage device. SOLUTION: The high-density storage device includes a housing and an assembly of memory and controller. The housing includes a plug part and a socket part for receiving a plug part of the other high-density storage device. The assembly of memory and controller is mounted on the housing, and includes a circuit board, a source controller integrated circuit and a memory integrated circuit. The circuit board has an upper surface and a bottom surface. The source controller integrated circuit is mounted on the bottom surface. The memory integrated circuit is mounted on the bottom surface of the circuit board. Since the source controller integrated circuit and the memory integrated circuit are mounted on the same side surface of the circuit board, the high-density storage device has a reduced size. Further, the socket part may be connected with a different high-density storage device. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an integrated circuit packaging process through a non-tape die attaching method that can reinforce die attaching strength to avoid separation of chips from a substrate. SOLUTION: The integrated circuit packaging process includes the steps of providing a substrate having a top surface, a bottom surface, and an aperture (step 1), applying a liquid die attaching material to the top surface of the substrate (step 2), carrying out a defoaming operation to exclude fine bubbles in the liquid die attaching material (step 3), carrying out a first annealing operation to change the liquid die attaching material to be half-cured and form a compact die attaching film (step 4), exposing multiple bonding pads to the aperture that are used for the compact die attaching film to bond the active surface of the chip to the top surface of the substrate, and have multiple bonding pads on the active surface of the chip (step 5), and performing a second annealing operation to cure up the compact die attaching film (step 6).
