Leistiko patent notebook (#110)

Describes several experiments on the out-diffusion of aluminum in FET devices. Proposes mask geometry designs for a “pentode replacement” and other FET devices. [Note: A copy of “Project plan for project #189, field effect transistors” prepared by the author in mid-1961 is inserted into page 88 of Moore LN#2.] Notes an experiment to study “the drift problem of the SCT” – C.T. Sah’s surface controlled transistor. (p. 34). This is one of the earliest Fairchild references to the instability issues that would plague MOS devices for the rest of decade. A pasted-in typed page of the draft of TR 236 (below) (p. 39).
