  • Patent number: 8338872
    Abstract: Transistors (21, 41) employing floating buried layers (BL) (72) may exhibit transient breakdown voltage (BVdss)TR significantly less than (BVdss)DC. It is found that this occurs because the floating BL (72) fails to rapidly follow the applied transient, causing the local electric field within the device to temporarily exceed avalanche conditions. (BVdss)TR of such transistors (69. 69?) can be improved to equal or exceed (BVdss)DC by including a charge pump capacitance (94, 94?) coupling the floating BL (72) to whichever high-side terminal (28, 47) receives the transient. The charge pump capacitance (94, 94?) may be external to the transistor (69, 69?), may be formed on the device surface (71) or, may be formed internally to the transistor (69-3, 69?-3) using a dielectric deep trench isolation wall (100) separating DC isolated sinker regions (86, 88) extending to the BL (72). The improvement is particularly useful for LDMOS devices.

A stress-inducing region is formed along a bottom of the recess, and a stressed layer is formed over the stress-inducing region. By having a stress-inducing region with a larger lattice structure than the stressed layer, a tensile strain may be created in a channel region of the semiconductor device and may be suitable for an NMOS device. By having a stress-inducing region with a smaller lattice structure than the stressed layer, a compressive strain may be created in the channel region of the semiconductor device and may be suitable for a PMOS device. Embodiments may be applied to various types of substrates and semiconductor devices, such as planar transistors and finFETs.

  • Patent number: 8304851
    Abstract: Conventional “on-chip” or monolithically integrated thermocouples are very mechanically sensitive and are expensive to manufacture. Here, however, thermocouples are provided that employ different thicknesses of thermal insulators to help create thermal differentials within an integrated circuit. By using these thermal insulators, standard manufacturing processes can be used to lower cost, and the mechanical sensitivity of the thermocouple is greatly decreased. Additionally, other features (which can be included through the use of standard manufacturing processes) to help trap and dissipate heat appropriately.

  • Patent number: 8257987
    Abstract: Films of III-nitride for semiconductor device growth are planarized using an etch-back method. The method includes coating a III-nitride surface having surface roughness features in the micron range with a sacrificial planarization material such as an appropriately chose photoresist. The sacrificial planarization material is then etched together with the III-nitride roughness features using dry etch methods such as inductively coupled plasma reactive ion etching. By closely matching the etch rates of the sacrificial planarization material and the III-nitride material, a planarized III-nitride surface is achieved. The etch-back process together with a high temperature annealing process yields a planarize III-nitride surface with surface roughness features reduced to the nm range. Planarized III-nitride, e.g., GaN, substrates and devices containing them are also provided.
