Title: Colour television signal subcarrier to horizontal sync (SCH) phase error        correction
Inventor: OADES DAVID
IPC: H04N9/44
Filed: 1993-01-18
Abstract: Circuitry is disclosed including detecting means 2, 3, 5, 7, 8, 13 which produces an output which varies in accordance with an SCH phase error, i.e. when a zero crossing point of a colour sub-carrier signal is non-coincident with a 50% amplitude point in the leading edge of a horizontal sync pulse. If the crossing point is out of synchronisation by a phase angle of > -90 DEG  to < +90 DEG  the SCH error occurs in a first frame. If by > -180 DEG  to < -90 DEG or > +90 DEG  and < +180 DEG  the SCH error occurs in a second frame. Correcting means 6, 15, 16 responds to the detecting means for automatically replacing prevalent horizontal sync pulses in the colour video signal with fresh horizontal sync pulses to maintain colour field integrity of the colour video signal. A feedback path 12 between the sampling circuit 8 and a phase shifter 7 introduces some hysteresis which avoids ambiguity in detecting non-coincidence occurring precisely between the first and second frames. <IMAGE>

Title: ROM coding by implant
Inventor: CHEN MIN-LIANG
IPC: H01L27/112
Filed: 1994-07-12
Abstract: A read only memory semiconductor integrated circuit device 100 includes an improved cell region and a method of manufacture therefor. The improved cell region includes a recessed dielectric region 300 overlying a gate electrode 160. Such a recessed dielectric region allows for an implanting or coding step to occur after the dielectric layer is applied to the surface of the device and this shortens product turn-around-time. The improved cell also includes an improved method of manufacture. Such method provides for the dielectric layer 300 to be formed over the gate electrode 160 of a partially completed MOSFET. The method further provides etching the upper portion of the dielectric layer overlying the gate electrode to form the recessed region 300. A step of coding or implanting is then performed to change the device from an enhancement mode MOSFET into depletion mode, thereby providing the ROM code for the designated cell. <IMAGE>
