    • Decoupling capacitors are frequently used in computer systems in order to control noise. In general, decoupling capacitors are placed as close as possible to the devices they protect in order to minimize the amount of line inductance and series resistance between the devices and the capacitors. An integrated circuit package includes a substrate (110, 210) having a first surface (111, 211) and an opposing second surface (112, 212), and a die platform (130, 230) adjacent to the first surface of the substrate. The substrate has a recess (120, 220) therein. The integrated circuit package further includes a capacitor (140, 240) in the recess of the substrate. The presence of a recess in the substrate provides an opportunity to reduce the separation distance between a die supported by the die platform and the decoupling capacitors. A further advantage of embodiments of the invention lies in its ability to maintain socket compatibility.
    • 去耦电容器经常用于计算机系统中以控制噪声。 通常,去耦电容器尽可能靠近其保护的器件,以便最小化器件与电容器之间的线路电感和串联电阻的数量。 集成电路封装包括具有第一表面(111,211)和相对的第二表面(112,212)的基板(110,210)以及与基板的第一表面相邻的模具平台(130,230)。 基板在其中具有凹部(120,220)。 集成电路封装还包括在衬底的凹部中的电容器(140,240)。 在衬底中存在凹陷提供了降低由模具平台支撑的模具与去耦电容器之间的间隔距离的机会。 本发明的实施例的另一优点在于其维持套接字兼容性的能力。
