Semiconductor apparatus with decoupling capacitor
View Patent ↗A lead frame type of semiconductor apparatus includes a die pad on which a semiconductor chip is mounted; ground terminals which are to be grounded; power supply terminals which are connected to a power supply; inner leads connected to the ground terminals and power supply terminals, in which a pair of adjacent inner leads for power supply terminal and ground terminal are extended inwardly; a chip capacitor mounting pad which is provided at inner ends of the extended inner leads; and a chip capacitor which is mounted on the chip capacitor mounting pad so that a decoupling capacitor is provided.
1. A semiconductor apparatus, comprising:
an organic material substrate;
a die pad formed on the organic material substrate and comprising a chip mounting area on which a semiconductor chip is mounted and ground bonding areas, the ground bonding areas extending from two opposite sides of the die pad;
ground terminals which are to be grounded;
power supply terminals which are supplied with electrical power;
first conductive patterns formed on the organic material substrate and being connected to the ground terminals and to the ground bonding areas;
second conductive patterns formed on the organic material substrate and being connected to the power supply terminals;
power supply bonding areas arranged between the die pad and the first and second conductive patterns and being connected to the second conductive patterns, the power supply bonding areas being arranged at another two opposite sides of the die pad; and
chip capacitors arranged and connected between the die pad and power supply bonding area so that a decoupling capacitor is provided.
2. A semiconductor apparatus according to claim 1 , wherein
the die pad is provided with a projection or ridge to define the chip mounting area and ground bonding areas.
3. A semiconductor apparatus according to claim 1 , wherein
the organic material substrate is provided with cavities in which the chip capacitors are mounted therein.
