Abstract
Techniques for integrating two-phase cooling into a microprocessor chip package lid are provided. In one aspect, a vapor chamber lid device includes: an evaporator plate; a condenser plate attached to the evaporator plate such that a cavity is formed between the evaporator plate and the condenser plate; a thermal insulation layer sandwiched between the evaporator plate and the condenser plate; and a working fluid enclosed within the cavity, wherein the working fluid partially fills the cavity. At least one heat-dissipating device can be placed in thermal contact with the evaporator plate via a thermal interface material. A method is also provided for forming the vapor chamber lid device.
