Definitions
- the present invention relates to a method of manufacturing a substrate-handle for temporarily bonding a substrate, in particular for applications in the fields of electronics, optics or optoelectronics.
- the invention also relates to a method of temporarily bonding a substrate to the substrate-handle and further aims a substrate-handle for temporary bonding of a substrate, as obtained by this method of manufacture.
- a support substrate which has a non-stick area in the center and a silicon crown (or glass) untreated on a peripheral area is thus obtained.
- This crown then ensures adhesion during bonding with the substrate on which an adhesive has been previously spread.
- a chemical attack at the peripheral portion of the stack weakens the bonding. Combined with the low adhesion obtained by the presence of the release layer, this attack makes possible the mechanical detachment of the substrate from its support.
- the carrier substrate thus obtained has a nonstick area in the center and an adhesive crown on a peripheral area so that it is not necessary to spread an adhesive component on the substrate.
- a second variant of the process can be envisaged with the following steps:
- peripheral part of the anti-adhesive component is removed by etching with a solvent of the anti-adhesive
- a support substrate having a central non-stick area an adhesive crown on a peripheral area is then obtained for bonding with a substrate.
- the present invention aims to remedy at least one of the aforementioned drawbacks. To this end, it proposes a method of manufacturing a substrate-handle intended for the temporary bonding of a substrate, the method comprising the steps of:
- the release layer comprising a central region and a peripheral region
- this method makes it possible to form a non-adhesive central portion on the support substrate and a peripheral cut-off portion, making it possible to receive the excess adhesive during bonding with the substrate so as to improve the flatness of the interface.
- this method is simple to implement and avoids performing a large number of preparation steps.
- the recess formed may have different types of shape, such as a step-shaped profile, a bevel or concave curvilinear shape.
- the term "recess" is distinguished from the typical canting or chamfering performed during the finishing of a substrate to facilitate its handling without generation of particles contaminating the clean rooms. This falling edge is illustrated in particular in a convex curvilinear shape for reasons of simplification and difference in scale between the dimension of the chamfer and the dimensions of the chamfered substrate. Thus it differs from the recess according to the present invention generally made according to angle / direction entering the volume of the substrate.
- the support substrate is solid. It is thus less fragile to handle in comparison with a substrate comprising a stack of layers and it has a volume with homogeneous chemical properties with respect in particular to etching reagents that can be used later.
- the adhesive / non-stickness measurements of a material have been made by inserting a layer of said material between two silicon substrates.
- the adhesion energy between these two silicon substrates assembled via this layer is greater than 1 J / m 2 or even greater than 1 .5 or even greater than 2 J / m 2 then it is a question of a layer of an adhesive material.
- the non-stick nature of a material is measured by inserting a layer of such material into the preceding stack to form a Si / adhesive / non-stick / Si stack.
- the adhesion energy is then measured by the same method.
- the layer in question is considered as nonstick when the measured adhesion energy is less than 900 mJ / m 2 and preferably less than 800 or even less than 500 mJ / m 2 .
- the dismounting of the substrate temporarily bonded to the handle substrate according to the method of the present document is all the easier as the difference in adhesion energy between the adhesive and the non-stick adhesive is greater than 100 mJ / cm 2 and advantageously greater than 500mJ / m 2 , or even greater than 1 J / m 2 .
- the recess formed in step c) consists in removing material from the periphery of the support substrate and the peripheral region of the release layer so that the recess has a width L, measured from the periphery. towards the center support substrate, substantially constant.
- width L varies at most 10 micrometers on the peripheral periphery of the support substrate.
- the recess is made very accurately to meet the expected value of width L to 10 micrometers.
- the recess formed in step c) has a height H of between 1 and 50 micrometers and a width L of between 1 and 50 mm.
- the height H is measured in a direction substantially perpendicular to the plane of the receiving face and the width L is measured in a radial direction.
- This height range H makes it possible to receive the surplus of adhesive and this range of width L ensures optimum bonding energy both for carrying out treatments on the substrate and for ensuring easy and good separation.
- the removal of material is carried out so that the width L varies by at most 1 micrometer (the value of the expected width L is obtained to within 1 micrometer).
- the homogeneity of the width L obtained guarantees a uniform subsequent bonding with the substrate, which then facilitates delamination by chemical etching or application of mechanical stress to the bonding interface between the substrate and the substrate-handle.
- the recess formed in step c) has a bottom whose roughness is between 1 and 500 nanometers RMS (acronym English of Root Mean Square) and preferably between 1 and 100 nanometers RMS. This roughness is particularly favorable for bonding with the substrate. All RMS roughnesses described in this document are determined by AFM atomic force microscopy on a field of 20x20 micrometers.
- the clipping of step c) is carried out by means of machining tools, such as a clipping saw or a ranger.
- This method is inexpensive and provides a high homogeneity in the removal of peripheral material.
- the width L of the trimming is obtained with a variation of only 10 microns and the height H with a variation of only 1 to 2 microns (in other words, the expected value of the height H is obtained to within 1 or 2 microns).
- the trimming of step c) is carried out by a photolithography step followed by an ion etching or chemical etching step.
- This method allows a precision of the homogeneity of the dimensions of the width L and the height H less than 1 micrometer.
- the clipping of step c) is carried out by a step of implanting ionic species, such as hydrogen, through the peripheral region of the nonstick layer followed by a treatment step Thermal exfoliation.
