Appeal No. 96-3998 Application No. 08/344,397 d) a single polysilicon layer having a predetermined thickness and resistivity present on said insulative layer, said single polysilicon layer including a polysilicon field plate portion subtended by said first portion of said insulative layer, serving as a field plate, and a gate portion subtended by said second portion of said insulative layer, serving as a gate, whereby said polysilicon field plate portion provides for increased transconductance of said transistor without reducing breakdown voltage to minimize the spacing between said source region and said drain region; e) a drain contact contacting said contact region; and f) a source contact contacting said source region, said source contact spaced from said drain contact, extending laterally towards said drain contact no further than said polysilicon field plate portion; a plurality of heater elements, each of said heater elements connected to one of said plurality of MOS transistors; and a plurality of orifices for expelling ink droplets, each of said orifices operatively associated with one of said plurality of heater elements.
