A target measurement device is provided. The target measurement device includes a fixing ring, a main body, and a transceiver. The fixing ring has a first surface. The main body is over the first surface of the fixing ring. The transceiver is coupled to the main body. The transceiver is at least movable between a center of the fixing ring to an edge of the fixing ring from a top view perspective. A method for measuring a target is also provided.

Target measurement device and method for measuring a target

A method includes providing a jig including a predetermined center and a magnetron installed on the jig; rotating the magnetron and obtaining a measured first magnetic flux density at the predetermined center of the jig; defining a first area of the magnetron based on the measured first magnetic flux density; rotating the magnetron and measuring a plurality of second magnetic flux densities within the first area of the magnetron; deriving a measured second magnetic flux density among the plurality of second magnetic flux densities; comparing the measured second magnetic flux density with a predetermined threshold; and performing an operation based on the comparison.

Analyzing method

An embodiment is a structure including a first fin over a substrate, a second fin over the substrate, the second fin being adjacent the first fin, an isolation region surrounding the first fin and the second fin, a gate structure along sidewalls and over upper surfaces of the first fin and the second fin, the gate structure defining channel regions in the first fin and the second fin, a source/drain region on the first fin and the second fin adjacent the gate structure, and an air gap separating the source/drain region from a top surface of the substrate.

FETs and methods of forming FETs

A measuring method is provided. A probe and a first sensor are disposed over a jig including a bar protruding from the jig. The probe is moved until a first surface of the probe is laterally aligned with a second surface of the bar facing the jig. A first distance between the second surface of the bar and the first sensor is obtained by the first sensor. The probe and the first sensor are disposed over a magnetron. Magnetic field intensities at different elevations above the magnetron are measured by the probe. A method for forming a semiconductor structure is also provided.
