    Abstract: Application form of and demand for an IC chip formed with a silicon wafer are expected to increase, and further reduction in cost is required. An object of the invention is to provide a structure of an IC chip and a process capable of producing at a lower cost. In view of the above described object, one feature of the invention is to provide the steps of forming a separation layer over an insulating substrate and forming a thin film integrated circuit having a semiconductor film as an active region over the separation layer, wherein the thin film integrated circuit is not separated. There is less limitation on the shape of a mother substrate in the case of using the insulating substrate, when compared with the case of taking a chip out of a circular silicon wafer. Accordingly, reduction in cost of an IC chip can be achieved.

    Abstract: Four regions (a narrow NMOS region, a wide NMOS region, a wide PMOS region, and a narrow PMOS region) are defined on a semiconductor substrate. Then, after a gate insulating film and a polysilicon film are sequentially formed on the semiconductor substrate, n-type impurities are introduced into the polysilicon film in the wide NMOS region. Next, by patterning the polysilicon film, gate electrodes are formed in the four regions. Then, n-type impurities are introduced into the gate electrodes in the narrow NMOS region and the wide NMOS region. As a result, an impurity concentration of the gate electrode in the narrow NMOS region becomes lower than that of the gate electrode in the wide NMOS region.

    Abstract: A dual channel JFET which can be integrated in an IC without adding process steps is disclosed. Pinch-off voltage is determined by lateral width of a first, vertical, channel near the source contact. Maximum drain voltage is determined by drain to gate separation and length of a second, horizontal, channel under the gate. Pinch-off voltage and maximum drain potential are dependent on lateral dimensions of the drain and gate wells and may be independently optimized. A method of fabricating the dual channel JFET is also disclosed.

    Abstract: A method for fabricating a CMOS-compatible MEMS device is disclosed. In particular, disclosed is a method of ordering the acts in the fabrication process of the two device types such that one device type will not be damaged by the fabrication process of the other device type. One aspect of the method involves first depositing a masking layer over a portion of a substrate layer to isolate areas for the formation of a second device type. The first device type is then fabricated on the unmasked portion of the substrate. A first device is then protected by depositing a masking layer over the first device. Next, a portion of the masking layer over the substrate is removed to expose areas to form a second device type. The second device type is then fabricated on the unmasked portion of the substrate. Finally, the masking layer over the first device type is removed.
