Fisiologia Humana Tresguerres 4ta Edicion Pdf 48l. June 26, 2019 . Semiconductor power devices may generate heat as a result of power loss. Typically, heat is removed from the power device with a heat sink, which is typically formed of a metal or metal-ceramic material, for example. In a device such as a power semiconductor, heat generated by the device is conducted through a die or wafer to the backside of the device, and then through a conductive substrate or die mounting substrate to the heat sink. Thermal resistivity is important in the design and construction of power devices. For example, high thermal resistivity can improve the thermal margin of the device, which is a design parameter related to the maximum allowable temperature increase of the device. Lower thermal resistivity can improve the power density of the device, which is a design parameter related to the efficiency of the device. Generally, thermal resistivity increases as a function of decreasing thickness and as a function of increasing material density. In the current state of the art, the thickness of the thermal substrate typically accounts for about 40% of the total thickness of the semiconductor die, and the material density of the thermal substrate is typically about 50% of the material density of the semiconductor die. This presents a trade-off between decreasing thermal resistivity, which typically occurs as a result of increasing material density, and increasing material strength, which typically occurs as a result of increasing thickness. Accordingly, it is desirable to provide a semiconductor die and a method for making the same that reduces thermal resistivity of the semiconductor die, without reducing material strength. It is also desirable to provide a semiconductor die and a method for making the same that reduces the thermal resistivity of the semiconductor die without substantially increasing thickness or material density of the thermal substrate. Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this background of the invention.
