    Abstract: The word conductors of a semiconductor integrated ROM are foreshortened where permitted by the organization of data in the memory. The space made available by the eliminated portions of the word conductors is used for electrical connection to the bit conductors from the sides of the array rather than at the ends. A space reduction of about thirty percent is achieved.

    Abstract: A method for making a MOSFET device (20) in a semiconductor body (10) includes the step of forming source and drain contact electrodes (12.1, 12.2) prior to growth of the gate oxide (10.3) and after formation of a high conductivity surface region (10.5). The exposed mutually opposing sidewall edges of each of the contact electrodes (12.1, 12.2) are coated with a sidewall silicon dioxide layer (15.1, 15.2), and the then exposed surface of the semiconductor body (10) between these sidewalls is etched to depth beneath the high conductivity surface region (10.5) in order to separate it into the source and drain regions (10.1, 10.2).Formation of the high conductivity region may be omitted by using Schottky barrier or impurity doped material for the contact electrodes (12.1, 12.2).

    Abstract: A random access memory (RAM) cell in 6H-SiC having storage times when all bias is removed long enough to be considered nonvolatile. The nonvolatile random access memory (NVRAM) cell comprises a bit line, a charge storage device in silicon carbide, and a transistor in silicon carbide connecting the charge storage device to the bit line. The bipolar NVRAM cell has a bipolar transistor with a base region, an emitter region, and a floating collector region, wherein the charge storage device in the bipolar NVRAM is a p-n junction adjacent the floating collector region of the cell. The metal-oxide-semiconductor (MOS) NVRAM has a MOS field effect transistor (MOSFET) with a channel region, a source region, and a drain region, wherein the charge storage device in the MOS NVRAM is a MOS capacitor adjacent the drain region of the MOSFET.

    Abstract: A dual-metal-trench silicon carbide Schottky pinch rectifier having a plurality of trenches formed in an n-type SiC substrate, with a Schottky contact having a relatively low barrier height on a mesa defined between adjacent ones of the trenches, and a Schottky contact having a relatively high barrier height at the bottom of each trench. The same metal used for the Schottky contact in each trench is deposited over the Schottky contact on the mesa. A simplified fabrication process is disclosed in which the high barrier height metal is deposited over the low barrier height metal and then used as an etch mask for reactive ion etching of the trenches to produce a self-aligned low barrier contact.

    Abstract: The decoder portion of a programable logic array (PLA) includes logic devices at crosspoints defined between the word (x) lines and the address (y) lines characteristic of a decoder portion. The devices are operative to combine two or more word lines to activate a single word line in the associated read only memory (ROM) in response to one of two or more possible inputs. The technique is effective even in cases where "don't care" conditions relating the two or more possible inputs cannot be found. A substantial reduction in chip area is achieved.
