  • Patent number: 4350991
    Abstract: A method for fabricating an N-channel silicon MOS field effect transistor on a P-type substrate. The structure retains the natural isolation between devices and the consequent higher device density in an integrated circuit structure than conventional double diffused MOS field effect transistor devices. The device is fabricated by using ion implantation to create an N-type surface layer in the channel and then overcompensating this layer to create a P-type region near the source by ion implanting P-type ions into the source junction region. The source to substrate capacitance is considerably less than that of conventional double diffused MOS devices which provides an improved circuit performance.

  • Patent number: 4266283
    Abstract: An electrically alterable read-mostly MOS memory (commonly referred to as E.sup.2 PROM) employing floating gate memory devices is described. Each word stored in memory may be separately accessed for reading and writing. The memory array is arranged with additional lines and selection means to prevent the high-level programming signals from the X-decoders from programming all the floating gate devices along a selected X-line. A high voltage circuit is described which permits the handling of potentials greater than the grounded gate breakdown voltage associated with the shallow junction devices used in the memory. A unique sensing amplifier is also disclosed which detects low currents at high speeds.

  • Patent number: 4189431
    Abstract: Polyenine compounds are provided having the naturally occurring geometry and a group which in the presence of acid initiates a carbocation cyclization to a steroid or A-nor-steroid structure, particularly the pregnane parent structure. The compounds are formed for the most part by condensation of two units prepared from readily available small molecules and are joined to form a polyenine, usually having a substituted carbocyclic ring which upon contact with a Lewis acid catalyst (includes protonic) cyclizes directly to provide the 5-membered D ring as well as substitution at the C-20 position.

  • Patent number: 4117234
    Abstract: Estrogenic steroids are synthesized by combining under conditions favoring the formation of a trans-olefin, a .gamma.-arylpropanal with a 5,5,8,8-tetraalkoxy Wittig reagent. After hydrolysis of the gem-diethers, the resulting dioxo is internally condensed to form a cyclopentenone. The ketone is reduced to an oxy group and the resulting 2-(6'-arylhex-3'-enyl-1)cyclopent-2-en-1-ol or derivative thereof is cyclized to the .DELTA..sup.13,17 -estrene, preferably 17-alkyl-.DELTA..sup.13,17 -estrene with the A ring aromatized. After epoxidation, the 17-alkyl derivative is rearranged to form the 13-alkyl-1,3,5(10)-estratien-17-one. New compounds are provided as intermediates and final products.

  • Patent number: 4064185
    Abstract: Compositions are provided as well as methods for preparing the compositions which serve as cyclization precursors for the preparation of C-11 alkenyl substituted steroids and nor-steroids. The alkenyl group may be converted after cyclization to a variety of heterosubstituents to provide heterofunctionalized C-11 steroids and nor-steroids. The compounds are provided having an initiator group, which has a chalcoxy atom in juxtaposition to a double bond, an olefinically unsaturated linking group and a terminating group which acts to from a carbocation which reacts with a nucleophile to provide a stable product. The C-11 substituent is found to provide upon cyclization the alpha-configuration, so that the subject compounds provide a direct route to the difficultly accessible alpha-C-11 substituted steroids, or, if desired, the alpha-configuration can be inverted to the beta-configuration.

  • Patent number: 4032579
    Abstract: Precursor compounds are provided for use in the synthesis of 11-chalcogensubstituted steroids and nor-steroids, particularly 18-, 19- and A-nor-steroids. The compounds are acyclic or substituted polyenine with the olefinic groups having the proper geometry to provide the natural ring fusions upon cyclization. To initiate cyclization, a chalcogen atom is positioned in relation to a double bond, so that on protonation of the chalcogen atom, the resulting carbocation will interact with the double bond to form a pi bond if the cyclization initiator is carbocyclic and a sigma bond if the cyclization initiator is acyclic. Upon cyclization, it is found that the substituent at C-11 of the resulting steroid is in the alpha position. Various methods are provided for producing the cyclization precursor.

  • Patent number: 3983572
    Abstract: The invention is concerned with methods for producing improved semiconductor devices. The invention is advantageously employable in the fabrication of insulated-gate field-effect transistor devices. The problem of accurately aligning the gate electrode over the channel region, lying between the source region and the drain region of a field effect transistor, is particularly addressed and solved. Accurate and precise field protection of all areas of the field-effect transistor surrounding the channel, source and drain regions is simply and effectively accomplished. The proper alignment of the gate electrode is largely accomplished by utilizing essentially the same mask structure to define the gate, source and drain regions. The same mask structure is utilized to define the area that is field protected.
