MIM unit structure and communication mechanism

MIM is a sandwich structure composed of a metal, insulator, and metal three-layer film. The MIM structure for liquid crystal display is shown in Figure 1, mainly

This article refers to the address: http://

There are two types: (1) Figure 1 (a) is a relatively common "T" shape structure. The process of this structure is relatively simple, and the MIM developed in the early stage is basically this form. However, the MIM area of ​​this structure is relatively large and has a large parasitic

Capacitance is detrimental to improving contrast and improving display quality. If you want to reduce the area, you need a large area, high resolution

Lithographic equipment. Not only increases the difficulty of the production process, the yield rate decreases, but also increases the cost, and is not suitable for large scale.

display. (2) Figure 1 (b) shows the lateral MIM structure developed, which is formed laterally on the scan line.


MIM decisive action
The M IM component is characterized by a non-linear change in its volt-ampere characteristics. LCD display is the use of this feature of MIM. When the applied bias voltage is reached

When a certain value V (closed voltage), the conductivity of the MIM changes abruptly and changes from the insulated state to the conductor state. Electricity through MIM

The flow also increases rapidly. MIM is in the "on" state. When the applied bias voltage on the MIM is less than VT, the MIM returns to its original state, MIM.

In the "lizard" state. The insulation properties of the insulation are not damaged throughout the "pass," "lizard" process. Figure 2 shows the Volt of MrM

Sex curve.

MIMI communication mechanism


Therefore, under the action of a strong field, a large amount of electrons on the donor level enter the insulating layer conduction band. And avalanche breakdown occurs under the action of a strong field. The relationship between its volt-ampere characteristics can be expressed by the formula (1). For the MIM whose insulation layer is Ta zO, the 13 PF value of the MIM obtained in actual work does not conform to the PooIe-Frenkel3L~ value and conforms to Schottky's

The theoretical value is s (13 PF = 2 13 s). This abnormal Poole-Frenke1 effect occurs mainly in the Ta zO film.

There is only a neutral trap level, so the Poole-F reakel effect cannot be shown. And the conductivity at this time

Also very low In order to solve this problem, deep donor energy must be formed in the Ta:O film by heat treatment and other processes.

Level to meet the requirements of liquid crystal display. Partially unbalanced defects can also be removed during processing.

Improve the stability of MIM.

 Micro motors Based on Dc Motor, Micro Motor belongs to the small size of dc motor,micro motor rotor, back cover, chassis, rotor winding is mainly copper, back cover most of the use of plastic material, motor shell use galvanized steel plate, the micro motor can be ROHS test.


A  micro motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of micro motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.

Operating temperature range:

Micro motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at  ordinary room temperature catalog specifications re based on use at ordinary room temperature  (approximately20~25℃.

If a micro motor  is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.

 

Storage temperature range:

Micro motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.

 

Service life:

The longevity of micro motor  is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.

 

when it come to volume production,we're a major player as well .each month,we rurn out  600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
