摘要:
In a method of forming a pattern structure, a cut-off portion of the node-separated line of a semiconductor device is formed by a double patterning process by using a connection portion of the sacrificial mask pattern and the mask pattern to thereby improve alignment margin. The alignment margin between the mask pattern and the sacrificial mask pattern is increased to an amount of the length of the connection portion of the sacrificial mask pattern. The lines adjacent to the node-separated line include a protrusion portion protruding toward the cut-off portion of the separated line.

The present invention comprises methods and devices for thermal treatment of a barrier to increase the permeability of the barrier. One form of increasing the permeability of the barrier comprises forming micropores which may be used for administration of active agents across the barrier, or may be used for sampling or collecting fluids, or may be used for detecting, measuring or determining analytes, or may be used for monitoring of physiological or other conditions. Devices of the present invention may comprise microheaters that are activated by inductive or ohmic heating power supply components.

摘要:
A method of manufacturing a semiconductor package that includes: forming a first board; forming second boards, in each of which at least one cavity is formed; attaching the second boards to both sides of the first board, such that the second boards are electrically connected with the first board; and connecting at least one component with the first board by a flip chip method by embedding the component in the cavity. The method can prevent damage to the semiconductor chips and lower manufacturing costs, while the connection material may also mitigate stresses, to prevent cracking in the boards and semiconductor chips, while preventing defects such as bending and warpage. Defects caused by temperature changes may also be avoided. Furthermore, it is not necessary to use an underfill in the portions where the semiconductor chips are connected with the printed circuit board, which allows for easier reworking and lower costs.

摘要:
A method of fabricating a semiconductor plastic package can include: providing a core board, which includes at least one pad, and which has a coefficient of thermal expansion of 9 ppm/° C. or lower; stacking a build-up insulation layer over the core board; forming an opening by removing a portion of the build-up insulation layer such that the pad is exposed to the exterior; and placing a semiconductor chip in the opening and electrically connecting the semiconductor chip with the pad. This method can be utilized to provide higher reliability in the connection between the semiconductor chip and the circuit board.
