A part of the electrode on the stepped portion side surface is arranged on the front surface of the stepped portion upper step (140t).

Provided is a method for manufacturing a dual-step structure gate electrode of a thin film field effect transistor.

The template basically comprises step holes which are arranged in an array formation identical to that of the pattern formed by the balls on the eventual BGA device.

Fuel gas is drawn off above the upper level of the grate on the side opposite the lateral feed of the gasifying agent.

The inner die (1) also is provided with a step, and the step of the inner die (1) is flush with the step of the outer die (2).

In one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights.

The first valve step (20) and the second valve step (20) are connected to the drive gear mechanism (40) in such a way that the first valve step (20) is actuated separately from the second valve step (30).

The reverse step-shape corresponding to the step-shape is filled with cured sealing material for sealing.

The stepped portion is formed around the position where a weld line may be formed without the stepped portion.

The differential valve has a smaller first step (20) and a larger second step (30) in addition to a drive gear mechanism (40).

The gate electrode of the planar gate and the gate electrode of the trench gate are connected on the trench gate.

The grill housing includes a unitary grill that has an integrated warming rack.
