Patent ID: 10622462

Abstract:
A method of making thin film transistor including: forming a gate electrode, forming a gate insulating layer on the gate electrode; locating a semiconductor layer on the gate insulating layer; placing stripe-shaped masks on the semiconductor layer, wherein the thickness of the stripe-shaped masks is H, the spacing distance between the stripe-shaped masks is L; depositing a first conductive film layer along a first direction, the thickness of the first conductive film layer is D, a first angle between the first direction and a direction along the thickness of the stripe-shaped masks is θ1, θ1<tan−1(L/H); depositing a second conductive film layer along a second direction, a second angle between the second direction and the direction along the thickness of the stripe-shaped masks is θ2, θ2<tan−1[L/(H+D)], 0<Htanθ1+(H+D)tanθ2−L<10 nm, the first conductive film layer forms a source electrode, the second conductive film layer forms a drain electrode.
