A semiconductor chip wet transfer method includes: preparing a transfer substrate that includes a plurality of recesses; supplying a liquid that includes semiconductor chips onto the plurality of recesses of the transfer substrate; aligning the semiconductor chips in the plurality of recesses by sweeping, with an align bar, an upper surface of the transfer substrate supplied with the liquid; and performing cleaning by removing semiconductor chips that are not aligned in the plurality of recesses by using a first magnetic force generating device disposed facing a lower surface of the transfer substrate.

Chip wet transfer method and equipment using magnetic force

A high electron mobility transistor (HEMT) includes a channel layer, a plurality of barrier layers, and a p-type semiconductor layer. The barrier layers have an energy band gap greater than that of the channel layer. A gate electrode is arranged on the p-type semiconductor layer. A source electrode and a drain electrode are apart from the p-type semiconductor layer and the gate electrode on the barrier layers. Impurity concentrations of the barrier layers are different from each other in a drift area between the source electrode and the drain electrode.

Disclosed are a fingerprint detection device and a method therefor. A fingerprint detection device includes: a touch panel; at least one amplifier including a first integrator amplifying an electrical signal received from the touch panel to a signal of a first polarity and a second integrator amplifying the electrical signal to a signal of a second polarity; and a processor configured to control the amplifier to perform a first integration process and a second integration process with respect to a plurality of electrical signals received from a plurality of nodes of the touch panel.

Fingerprint detection device and method thereof

Provided are a combined fingerprint recognition touch sensor, an electronic apparatus including the same, and a fingerprint enrollment method to which the same is applied. The combined fingerprint recognition touch sensor includes parallel transmission lines extending in a touch sensing region, and a plurality of parallel reception lines extending in the touch sensing region to intersect the transmission lines. A signal transmitter includes a plurality of transmission groups so as to apply driving signals to the transmission lines. A storage is configured to store an enrolled fingerprint image to be compared with an enrolled fingerprint for fingerprint authentication. In the fingerprint enrollment mode, a fingerprint image of a finger is obtained through one touch operation by applying driving signals to transmission lines belonging to two or more transmission groups and reading a fingerprint image of a sensing zone including an initial touch region and a surrounding region.
