Contact pin and power module package having the same

A power module package having a contact pin, the power module package comprising:

• a first substrate mounted with first semiconductor chips;
• a second substrate mounted with second semiconductor chips;
• and a contact pin including a deformation part elastically deformed, connection parts coupled to both ends of the deformation part, and contact parts coupled to the connection parts coupled to both ends of the deformation part, respectively, and having one end coupled to the connection part and the other end, wherein:
• the contact pin is disposed between the first and second substrates to electrically connect the first and second substrates to each other while vertically supporting the first and substrates, the first and second substrates have one surface and the other surface, respectively, the first substrate includes chip mounting pads and external connection pads that are formed on one surface thereof, the second substrate includes chip mounting pads formed on one surface thereof and external connection pads formed on the other surface thereof, the first and second semiconductor chips are mounted on the chip mounting pad on one surface of the first substrate and the chip mounting pad on one surface of the second substrate, respectively, and the contact pin has one portion and the other portion and is disposed so that a contact part of one portion contacts the external connection pad on one surface of the first substrate and a contact part of the other portion contacts the external connection pad on the other surface of the second substrate, wherein the first semiconductor chip is a power device, has one surface and the other surface, and is mounted on the first substrate so that one surface contacts the chip mounting pad on one surface of the first substrate and the other surface is exposed upwardly, the other surface of the first semiconductor chip exposed upwardly is provided with an electrode receiving a control signal for driving the first semiconductor chip, and the contact pin is disposed so that the contact parts of one portion and the other portion contact the electrode of the other surface of the first semiconductor chip and the external connection pad of the other surface of the second substrate, respectively.
