Claim Text:
1. An integrated chip with a micro-electro-mechanical system (MEMS) and an integrated circuit mounted therein, comprising: a first chip, which comprises a first substrate defining a top-to-bottom direction, an electrical connection portion disposed in the first substrate and extending from the top face to the bottom face, an oxide layer disposed on a top face of the first substrate, an MEMS component layer disposed on the substrate and comprising a movable sensitive portion movable in a horizontal plane perpendicular to the top-to-bottom direction and a fixing portion with portions thereof penetrating the oxide layer to electrically connect with the electrical connection portion, a first lead layer formed on the oxide layer and below the movable sensitive portion with a portion thereof electrically connecting with the MEMS component layer, a first electrical bonding point disposed on the fixing portion of the MEMS component layer, an electrical connection layer disposed on an bottom face of the first substrate, wherein the first electrical bonding point and the electrical connection layer are electrically connected via the electrical connection portion and the MEMS component layer; and a second chip, which comprises a second substrate with a bottom surface toward the top face of the first substrate, the second chip being disposed on the first chip, the second chip comprising a second lead layer disposed on the bottom surface of the second substrate and a second electrical bonding point disposed on and below the bottom surface of the second substrate, the second electrical bonding point electrically connecting with the second lead layer and bonded with the first electrical bonding point, the second lead layer and the first lead layer being symmetrically disposed on two sides of the movable sensitive portion.
