Abstract

An embodiment of the present invention discloses a chip transfer substrate and a chip transfer method. The chip transfer substrate comprises a first base layer, chip bases arranged on the first base layer, and a stretching film layer disposed between adjacent chip bases, wherein the stretching film layer is used for generating extension deformation in performing a first operation and generating contraction deformation in performing a second operation. According to the embodiment of the invention, the problem that the efficiency, the yield rate and the transfer precision of the mass transfer ofchips are difficult to meet micro component manufacturing requirements in an existing micro component manufacturing process is solved.

Description

technical field [0001] The present application relates to but not limited to the fields of display technology and semiconductor process technology, especially a chip transfer substrate and a chip transfer method. Background technique [0002] With the development of display technology, the manufacturing process of micro-components has become a development trend of the display panel, such as micro-light emitting diode (Light Emitting Diode, referred to as: LED) (ie, Mirco-LED) technology. [0003] In the fabrication process of microcomponents, the microcomponents should be formed on the donor substrate first, and then transferred to the receiving substrate. Based on the current process manufacturing foundation, there are relatively mature process methods for making thin film transistor (Thin film transistor, abbreviated as: TFT) arrays, Mirco-LED chips and driver integrated circuit (abbreviated as: IC) chips; however , The mass transfer of Mirco-LED chips is a difficult poin...
