V-GROOVE MOS (VMOS) VMOS Structure . The structure of VMO S is similar to short-channel power FET t hat is constructed as a vertical structure. The operation is same as that of a Double-Diffused MO S (DMOS) device. Take a look at the figure below to know more about the VMOS structure.. BST70A BST70A; N-channel Vertical D-mos Transistor . Product specification File under Discrete Semiconductors, SC13b April 1995. DESCRIPTION N-channel enhancement mode vertical D-MOS transistor in TO-92 variant envelope and intended for use in relay, high-speed and line-transformer drivers.. A Physically Based Analytical Model for Vertical DMOS Transistors · Abstract An approach for a physically based analytical DC- and AC-model for vertical DMOS (double diffused MOS) transistors is presented. It accounts for non-uniform channel doping concentration in.
In a normal MOS device, this leads to low voltage body-to-drain junction breakdown. However, DMOS is a vertical MOS device so it can employ a small length while having a high breakdown voltage (up to hundreds of volts) since most of the depletion region between the body and substrate is lightly doped.. IEEE TRANSACTIONS ON ELECTRON DEVICES, VOL. 43, NO. 8, AUGUST 1996 1243 Noise in DMOS Transistors in a BICMOS-Technology Ronald van Langevelde, Student Member, IEEE, Stefaan Blieck, and L. K. J. Vandamme Abstruct- An experimental and theoretical study of the l/f noise and the thermal noise in double-diffused MOS (DMOS) transistors in a BICMOS-technology has been carried out.. Further, there are a wide variety of power MOSFET structures like Vertical Diffused MOS (VDMOS) or Double-Diffused MOS or DMOS, UMOS or Trench-MOS, VMOS, etc. Figure 1 show an n-substrate VDMOS made of n-substrate and an n-epitaxial layer into which p and n+ regions are embedded into using double diffusion process..

Jun 15, 1993 · A novel double diffused complementary MOS (DCMOS) logic family is disclosed which allows greater tolerance to total dose gamma radiation. The logic family may be fabricated in conventional power BiCMOS IC technology in which complementary power DMOS output devices and Bi-polar transistors are integrated with high performance complementary MOS devices to perform both digital.
invention also relates to double diffused MOS ("DMOS') transistors. A DMOS transistor is a MOS transistor having a channel length defined by the difference in diffusion of sequentially introduced impurities from a common edge or boundary. One example of a prior art process for manufacturing a DMOS transistor is discussed in U.S.. Self-aligned polysilicon gate technology was applied to double-diffused MOS (DMOS) construction in a manner that retains processing simplicity and effectively eliminates parasitic overlap capacitance because of the self-aligning feature. Depletion mode load devices with the same dimensions as the DMOS transistors were integrated..
