Title: Process for producing a high-density integrated read-only memory
Inventor: FORTINO ANDREAS GUILLERMO
IPC: H01L29/08
Filed: 1980-07-24
Granted: 1986-07-24
Abstract: A method of making a transistor array includes forming a plurality of gate electrodes insulated from a semiconductor substrate having an impurity of a given conductivity, introducing a first impurity having a conductivity opposite to that of the given conductivity into a given region of the substrate which is adjacent to an edge of each of the gate electrodes, introducing a second impurity having the given conductivity into given regions adjacent to selected gate electrodes, the second impurity having a significantly higher diffusivity than that of the first impurity in the semiconductor substrate, and driving the second impurity along the surface of the semiconductor substrate to form in the substrate under each of the selected gate electrodes a region having a concentration of impurity of the given conductivity higher than that of the semiconductor substrate. The transistor array may be used, e.g. to make a read only memory (ROM) by connecting appropriate current sensing means to each of the given regions to indicate the presence or absence of the higher diffusivity impurity when a predetermined voltage is applied to the gate electrodes. In one embodiment, the semiconductor substrate is made of P type conductivity, the first impurity is arsenic which produces N type conductivity regions and the second impurity is boron, which produces P type conductivity. Since boron has a higher diffusivity than arsenic, after they are driven by heating the boron impurity produces a high threshold region under the gate electrode when introduced in sufficiently high concentration.

Title: Improved fluid flow control valve
Inventor: GOLDSMITH DEREK JOHN
IPC: F16K11/00

Granted: 1986-01-02
Abstract: A mixing valve for hot and cold domestic water has a control member (20,22 and 23) movable within a body (12) whereby axial movement of the control member controls opening and closing of communication from hot and cold inlets (13 and 14) to an outlet (32, 2) and rotation of the control member controls the relative proportions of fluid flow from respective inlets to the outlet. A pressure chamber (90) is supplied with pressure fluid from the inlets for assisting closing action of the valve upon closure of a vent (28,30) from the pressure chamber. In order to resist pressure surges at either inlet a restricted aperture (83) is provided to reduce flow from a reducing volume movement damping chamber towards the end of closing movement of the valve control member to prevent the final portion of the valve closing movement being too sudden.
