## Abstract

Modules and methods of assembly are described. A module includes a lid mounted on a module substrate and covering a component. A stiffener structure may optionally be mounted between the lid and module substrate. A recess can be formed in any of an outer wall bottom surface of the lid, and top or bottom surface of the stiffener structure such that an adhesive layer at least partially fills the recess.

## Claims

### Claim 1

A module comprising:
a module substrate;
a component on a top side of the module substrate;
a stiffener structure mounted on the top side of the module substrate, the stiffener including a flat top surface; and
a lid mounted on the flat top surface of the stiffener structure and covering the component, wherein the lid comprises a bottom surface and a lid recess in the bottom surface,
wherein the stiffener structure flat top surface is bonded to the bottom surface of the lid with a first adhesive layer that at least partially fills the lid recess in the bottom surface of the lid.

### Claim 2 (depends on 1)

The module of claim 1, wherein the lid recess is along an outer portion of an outer wall of the lid.

### Claim 3 (depends on 1)

The module of claim 1, wherein the lid recess is along an inner portion of an outer wall of the lid.

### Claim 4 (depends on 1)

The module of claim 1, wherein the lid recess includes a plurality of steps.

### Claim 5 (depends on 1)

The module of claim 1, wherein the lid recess is sloped or curved.

### Claim 6 (depends on 1)

The module of claim 1, further comprising a second adhesive layer bonding the stiffener structure to the top side of the module substrate.

### Claim 7 (depends on 1)

The module of claim 1, wherein the stiffener structure is formed of a material with lower coefficient of thermal expansion (CTE) than the lid.

### Claim 8 (depends on 1)

The module of claim 1, wherein the lid includes a plurality of local peripheral reinforcement structures extending laterally adjacent to the stiffener structure.

### Claim 9 (depends on 8)

The module of claim 8, wherein the plurality of local peripheral reinforcement structures is located at corners of the lid.

### Claim 10 (depends on 8)

The module of claim 8, wherein the plurality of local peripheral reinforcement structures is located along side edges of the lid.

### Claim 11

A module comprising:
a module substrate;
a component on a top side of the module substrate;
a stiffener structure mounted on a flat surface of the top side of the module substrate;
a lid mounted on the stiffener structure and covering the component;
a first adhesive layer bonding a top surface of the stiffener structure to the lid;
a second adhesive layer bonding a bottom surface of the stiffener structure to the module substrate; and
a first stiffener recess formed in the bottom surface of the stiffener structure;
wherein the second adhesive layer at least partially fills the first stiffener recess.

### Claim 12 (depends on 11)

The module of claim 11, further comprising a second stiffener recess formed in a top surface of the stiffener structure.

### Claim 13 (depends on 11)

The module of claim 11, wherein the first stiffener recess includes a plurality of steps.

### Claim 14 (depends on 11)

The module of claim 11, wherein the first stiffener recess is sloped or curved.

### Claim 15 (depends on 11)

The module of claim 11, wherein the lid includes a plurality of local peripheral reinforcement structures extending laterally adjacent to and outside of a lateral periphery of the stiffener structure.

### Claim 16

A module comprising:
a module substrate;
a component on a top side of the module substrate;
a stiffener structure mounted on the top side of the module substrate; and
a lid mounted on the stiffener structure and covering the component;
wherein the lid includes a plurality of local peripheral reinforcement structures extending laterally adjacent to and outside of a lateral periphery of the stiffener structure.

### Claim 17 (depends on 16)

The module of claim 16, wherein the plurality of local peripheral reinforcement structures is located at corners of the lid.

### Claim 18 (depends on 17)

The module of claim 17, wherein the plurality of local peripheral reinforcement structures is located along side edges of the lid.
